Sleep Advisor’s Testing Methodology

At Sleep Advisor, our mattress reviews are based on findings from in-person tests that allow us to have a genuine understanding of how the mattress feels and performs. We look at features that are valuable to consumers, such as temperature control, bounce, edge support, and motion isolation.

We also evaluate mattress performance for back, side, and stomach sleeping. Lying in different positions lets us know how supportive the bed is and if it’s good at relieving pressure.

For this roundup, we prioritized features that are especially important for king sized mattresses. We paid special attention to components such as mattress thickness, support elements for couples, weight capacity, and cooling.

Why the Emma Hybrid Comfort Earned Editor’s Pick

If you’re in search of a highly durable, firm-feeling king-size bed, the Emma Hybrid Comfort was created with you in mind. This mattress caters to a variety of sleepers, including couples, with its extra-strong hybrid construction.

Underneath its moisture-wicking cover, you’ll find three foam layers that provide cooling, pressure relief, and motion isolation. The mattress’s spring unit boasts seven zones of sturdy coils and rests on top of an extra-dense foam base. On top of that, it’s got a nice price–under $2,000 dollars. That’s why we’ve given it top spot.

What’s the Emma Hybrid Comfort Made Of?

The Emma Hybrid Comfort is 13 inches tall and features six layers. Its breathable cover protects the first comfort layer of Airgocell® Foam—a material rife with air pockets that help with temperature regulation.

Next is a layer of memory foam that assists with motion isolation and pressure relief, and after that is a layer of HRX (High Resiliency Xtra) Foam for bracing support.

The spring unit beneath is divided into seven zones that give specialized amounts of pushback to different body parts. The coils are individually wrapped and sit atop a dense base of foundational foam.

Looking at the Emma Hybrid Construction in the lab
Looking at the Emma Hybrid Comfort construction while mattress testing

My Take: The Emma Hybrid Comfort is an exceptionally firm mattress that nevertheless relieves pressure from key areas. Its sturdy construction should be a good fit for plus-sized and stomach sleepers, and the affordable price sure doesn’t hurt.

What I Liked

  • Lots of lift – This mattress takes spinal alignment very seriously. I felt buoyed in all sleeping positions, with no worries at all about too much sinkage.
  • Affordability – This is a durable hybrid bed priced at less than $2,000 for a king. It may not be as fancy as other tricked-out models, but it delivers lots of support for less money.

Potential Drawbacks

  • Quite firm – Although our tests found that the Emma Hybrid Comfort was good at preventing pressure buildup, it still feels very firm. Lightweight people and side sleepers will probably want a softer bed.
  • A little noisy – When I moved around on this bed, I could hear a somewhat crinkly noise from one of the foam layers. It didn’t prevent me from getting comfortable, but it warrants mentioning.

Customer Reviews of the Emma Hybrid Comfort

This is a fairly new mattress, so Emma’s site doesn’t have many reviews yet, but early customers already rate it an impressive 5 out of 5 stars. So far customers appreciate the Emma Hybrid Comfort mattress for its excellent motion isolation, but some have reported that it may have a slight initial off-gassing odor upon unboxing.

Why the Helix Midnight Earned Best King-Size Mattress for Side Sleepers

Side sleepers in search of a king-size bed need to prioritize two things: pressure relief and versatility. Pressure relief because their hips and shoulders will bear the brunt of their body weight when they’re lying down, and versatility because a king-size mattress should be able to accommodate more than one person.

The Helix Midnight was built to satisfy both requirements. My fellow tester Emma liked how her pressure points felt like they “have a little cushion around them” on this bed. She also praised its responsiveness and its medium-firm feel, features which make it suitable for a few different sleep styles.

What’s the Helix Midnight Made Of?

The Helix Midnight is 11.5 inches tall and has six layers, including its top cover.

That cover is made of soft, breathable fabric, but can be swapped for a GlacioTex™ Cooling Cover for an additional fee if you’re looking for added heat resistance. You can also order an extra pillow top layer to accompany the GlacioTex™ cover.

Underneath is a layer of Memory Plus Foam, Helix’s proprietary material that offers pressure relief and a soothing amount of give.

A closer look at the Helix Midnight mattress construction
A closer look at the Helix Midnight construction

It segues into two distinct layers of Helix Response Foam: one that cradles, and one that’s more supportive.

The Midnight’s coil unit consists of pocketed coils that are stronger on the long edges of the bed. They’re backed up by a sturdy base of DuraDense foam.

Our Take: “I like how the foams feel soft, but not too soft, like I’m sinking in and getting stuck.” Emma Mattei, Sleep Advisor Mattress Tester

What We Liked

  • Bouncy springs, motion-dampening foams – “This bed is a hybrid with decent bounce, so we were actually really surprised by how well it isolated motion,” said Emma. If you’re going to share your king-size bed with a partner, this balance should come in handy.
  • Great for back sleepers, too – Helix engineered this mattress for side sleepers in particular, but Emma thought its mix of cushioning and support was also “just right” for back sleepers. If you shift between your side and back as you snooze, even better!

Potential Drawbacks

  • Too firm for some, too soft for others – The Midnight is best for back and side sleepers, or people who switch back and forth between those two positions. Per Emma, it’s a bit too soft for exclusive stomach sleepers, and might even be too firm for lighter people who only doze on their sides.
  • Helix’s most basic model – This bed is part of Helix’s “Core Collection,” and doesn’t have the bonus features of their more expensive beds. You’ll have to pay extra for a cooling cover, for example, and there’s increased edge support only on the long sides rather than lining the full perimeter.

Customer Reviews of the Helix Midnight Mattress

The Helix Midnight rates 4.5 stars out of 5 on Helix’s website. The main negative is that reviewers tend to find it too soft for their liking and feel as though they’re sinking. But overall, users say they’re getting a great nights’ sleep and some pain relief.

Why the WinkBed Earned Best King-Size Hybrid Mattress

Hybrid mattresses are all the rage these days, bypassing all-foam and traditional innerspring beds in popularity. The combination of cozy foams and responsive coils is tough to beat, and if you’re shopping for a king bed, you’ll want a hybrid that plays to the advantages of this larger size.

For my money, I nominate the WinkBed. It’s a mattress with handcrafted touches and an especially durable zoned coil unit beneath its softer foams. Testers Sean and Mark both loved how customizable it is, and also complimented its superior craftsmanship.

What’s the WinkBed Made Of?

The WinkBed has four firmness options you can choose from: Softer, Luxury Firm, Firmer, and Plus, the last of which is designed for heavier sleepers. Regardless of the feel you pick, it’ll stand around 13.5 inches tall.

At the top of the bed is a Tencel™ cover with breathable fabric made from Eucalyptus wood pulp.

It protects the plush foam of the Euro pillow top beneath. Additional foam layers—including a LumbarLayer™ that support the lower back—eventually lead into the innerspring unit.

WinkBeds Mattress Construction
Construction of the WinkBed mattress

The coils in the WinkBed are split into zones that offer increased pressure relief or pushback, depending on where they’re located. They’re also reinforced along the edges to maximize your usable sleep space.

Our Take: “I’ve had the opportunity to try out the WinkBed mattress a number of times … I really like that these are handmade, that they’re tufted, and that you lay down on it and you can really feel that pressure relief.” Mark Mattei, Sleep Advisor Mattress Tester

What We Liked

  • Durability you can feel – According to Sean, the WinkBed is “literally a strong and sturdy bed.” The coils feel robust and the foams should resist sagging over time. The brand boasts that they achieve this longevity by testing their mattresses in a third-party facility, subjecting them to compressions that mimic the effects of decades of use.
  • Multiple firmness options – Mark gave the WinkBed points for its four available models, which enable you to “choose what style is going to best fit your body.” An exclusive side sleeper, he enjoyed the Luxury Firm’s mix of softness and support.

Potential Drawbacks

  • It won’t hug you – Sean said that resting on top of the WinkBed felt lovely, but didn’t have that signature memory-foam feel. If you want to really sink into your mattress, you probably don’t want a hybrid.
  • It’s not cheap – Hybrids tend to cost more than their all-foam counterparts, and this mattress is no exception. If you’re on a tight budget, you’ll want to wait for a sale before purchasing a king-size WinkBed.

Customer Reviews of the WinkBed

On the WinkBeds site, the WinkBed earns a 4.8 out of 5 stars. One drawback of the WinkBed mattress is that it might be too expensive for budget-conscious shoppers, but overall it offers excellent durability and customizable firmness options.

Why the Saatva Classic Earned Best King-Size Mattress for Back Pain

The Saatva Classic has more back-friendly features than most other beds I’ve reviewed—even the quilting in its cover is designed to help support your lumbar spine. It’s backed up by a specially positioned strip of memory foam, zoned pocketed coils, and a Lumbar Zone® Active Spinal Wire that bolsters the same lumbar region.

So, if you’re looking for a king-size bed that can help relieve back pain, this is the one I like to recommend first.

What’s the Saatva Classic Made Of?

You can order your Saatva Classic in one of two heights: 11.5 or 14.5 inches. You’ll also be able to choose between Plush Soft, Luxury Firm, and Firm models.

At the surface of the bed is a 3-inch Euro pillow top that gives the Classic its hotel-quality feel. It’s made of soft foam dressed in an organic cotton cover, with firmer quilting in the middle to lift your lumbar spine.

A memory foam “crown” stretches across the middle of the bed beneath the pillow top, further boosting the lumbar region. It leads into the first of two innerspring units.

This one has individually wrapped coils that are stronger in the middle, where you’re likely putting the most pressure on the bed.

The inside of the Saatva Classic Mattress
Saatva mattress construction

The second innerspring unit consists of interconnected coils that permit lots of airflow and should stand up to years of use. A Lumbar Zone® Active Spinal Wire stretched amongst the springs also prevents sagging and helps keep your back properly aligned.

Around the edges of the bed, a frame of high-density foam buttresses the sides and keeps them from dipping too low, even when you’re lying or sitting on them.

My Take: Every body type and sleeping position can get what they need from this bed, which is very rare in the mattress landscape.

What I Liked

  • More customization than most – Lots of mattresses offer different firmness options, but the Saatva Classic also lets you pick between two heights. The dual innerspring model really does grant enough underlying support for any sleeping position, so most people should be able to make this bed work for them.
  • White glove delivery – When it comes to setting up your new mattress, Saatva is all about easing your stress. Their team brings the bed into the room you designate, sets it up, and will even take away your old mattress as part of their delivery package.

Potential Drawbacks

  • It cradles but doesn’t hug – Remember, the Classic has two innerspring systems inside it. Even with a soft pillow top, it’s not going to feel as hug-like as an all-foam bed. Some people like that “on top of the mattress” feeling, and others would rather sink a bit deeper.
  • Not the coolest – The Saatva Classic stayed comfortably cool while I was testing it, but it didn’t go above and beyond with its temperature regulation. If you’re a particularly hot sleeper, I’d advise you to look into beds with phase change materials and other fancy cooling mechanisms.

Customer Reviews of the Saatva Classic

The Classic has garnered more than 3,000 online reviews on Saatva’s website, and sits at 4.8 out of 5 stars. Negative reviews tend to highlight the fact that it can take a bit of time to get your made-to-order bed delivered. But one-star reviews make up about 1% of the review pool, and most customers love the easy delivery process as well as the mattress’s effectiveness at helping with back pain.

Why the Nolah Evolution Earned Best King-Size Mattress for Couples

At 15 inches tall, a king-size Nolah Evolution cuts a striking figure in any bedroom. Its opulent construction includes seven total layers, plus an upper gusset that encourages heat to leave the mattress. With all of that material, it’s no surprise that it stands up well to the challenges of partnered sleeping.

“This is an excellent mattress for couples,” said our tester Stuart. “You could build your house on Nolah’s edge support.” Another one of our reviewers, Liz, added that these sturdy edges made getting in and out of bed a breeze, even though the mattress is so tall. Stuart also complimented the Evolution’s motion isolation, which should prove advantageous to light sleepers who snooze alongside a loved one.

What’s the Nolah Evolution Made Of?

Listing the materials inside the Nolah Evolution is no easy feat, as this mattress has seven layers (including its top cover) and is 15 inches thick. You can order this mattress in one of three firmness levels: Plush, Luxury Firm, or Firm.

At the top of the mattress, cooling is the name of the game. An organic cotton cover with heat-transferring fibers protects a 2-inch Euro topper quilted with breathable foam.

Even the quilting in this topper is “high thermal conductivity,” meaning it can attract excess heat away from the body. The topper is also encased by a gusset that further dispels unwanted warmth.

Taking a look at the Nolah Evolution mattress construction
Deep Dive into the Nolah Evolution construction

Next is a 2-inch layer of Nolah’s proprietary AirFoamICE™ material. This graphite-infused foam reputedly beats memory foam with its capacity for pressure relief, cooling, and standing up to wear and tear. It’s followed by 2 inches of a supportive, high-resilience foam and an inch of transition foam that adds some bounce and responsiveness to the mix.

Beneath the foam comfort layers is an 8-inch coil unit. Crucially, these coils are zoned into three regions that provide specialized amounts of pushback to different parts of the body—you’ll feel a bit more bolstered under your lower back, and more cushioned elsewhere. Thicker coils around the bed’s perimeter lend the mattress its memorable edge support.

All of these layers rest on a robust foundation made from recycled plant fiber.

Our Take: “[The Nolah Evolution] also has great motion isolation, so you shouldn’t have to crawl around like you’re stuck in slow-motion so you don’t wake up your partner.” Stuart Petty, Sleep Advisor Mattress Tester

What We Liked

  • Targeted support – Stuart said he could actually feel the support zones in this bed buoying different portions of his body, giving each place the right amount of pushback. At the same time, he felt “gently cradle[d]” by the plush comfort layers in the upper half of the bed.
  • It prevents pressure buildup – Liz, a back and side sleeper who often experiences joint pain, admired the Evolution’s pressure-relieving powers. “I really love the relief I get from the pressure in my hips,” she said.

Potential Drawbacks

  • Too soft for stomach sleeping – “Stomach sleepers may find that their hips and lower back sink pretty deep into this mattress,” said Stuart. “It may not be the most comfortable for long-term sleep.”
  • Large and hefty – With a king-size mattress this luxurious, transport can be a pain. “It’s thicker than most of the mattresses we work with,” Stuart commented. Thankfully, the Nolah Evolution arrives at your home in a box, so it’ll be much easier to move on its first trip to your bedroom.

Customer Reviews of the Nolah Evolution

The Nolah Evolution has netted an average of 4.9 out of 5 stars on Nolah’s website across hundreds of customer reviews. Buyers seem to value the brand’s dedicated customer service and the pressure-relieving feel of the bed, though some say it doesn’t run quite as cool as they’d hoped.

Why the DreamCloud Premier Earned Best Soft King-Size Mattress

The DreamCloud Premier is an extra-luxurious version of one of my favorite mattress, the DreamCloud. It has some additional padding up top that give it a memorably plush feel, though it doesn’t lose any of the stalwart support from its innerspring unit.

In my opinion, a king-sized version of this bed is bound to make you feel like pampered royalty—though stomach sleepers should probably look for a firmer model.

What’s the DreamCloud Premier Made Of?

The DreamCloud Premier is 14 inches high with six total layers, including its top cover. That cover is made with a soft cashmere-blend and quilted to 2 inches of pressure-relieving foams: 1 inch of gel-infused memory foam, and 1 inch of plush foam.

Next up is a 2.5-inch layer of transitional foam with a slightly firmer feel to assist with spinal alignment.

It leads into the innerspring unit, where pocketed coils allow for cooling airflow. The springs are also reinforced along the edges.

Finally, a layer of thick, stable foam forms the bottom layer of the bed. All of the inner layers are contained within a lower cover, which also features handles for intuitive transport.

DreamCloud Premier Mattress Construction
Look inside at the DreamCloud Premier mattress construction

My Take: Let’s talk about pressure relief: The memory foam and soft foam at the mattress surface really cradle the body’s key areas.

What I Liked

  • Heaven for side sleepers – I heartily recommend this bed to all my side sleepers out there, because it’s soft enough to really cushion the hips and shoulders without sacrificing base support.
  • Fairly priced luxury – DreamCloud prices their beds very attractively for what you’re getting. The cashmere-blend cover and multiple inner foam layers elevate this mattress above many other hybrids, but you can nab a king-size version for less than $2,000 when sales are active.

Potential Drawbacks

  • Motion isolation isn’t awesome – Bigger movements will definitely shake this bed, though the foam layers in the upper portion absorb smaller ripples.
  • Lacking in edge support – DreamCloud doesn’t have the best track record when it comes to edge support. The sides felt fine when I was lying down, but when I sat on them, there was a lot of sagging. This may not be a big concern if you’re getting a king-size mattress, though!

Customer Reviews of the DreamCloud Premier

Coming in at 4.5 out of 5 stars on DreamCloud’s site, the DreamCloud Premier receives a majority of positive reviews. Customers praise the DreamCloud Premier mattress for its luxury feel, but some have noted that it may not be the best choice for those on a tighter budget.

Why the Helix Dawn Earned Best Firm King-Size Mattress

The spring unit and the proprietary foams in the Helix Dawn give it a firmer feel that’s perfect for people who prefer minimal sinkage. Instead of classic memory foam, this king-size bed features Helix Dynamic Foam—a material that emulates the airy feel of latex—as its first foam layer. Back and stomach sleepers should appreciate the even, stable support that it offers.

What’s the Helix Dawn Made Of?

The Helix Dawn is 11.5 inches tall and has five total layers. It comes standard with a soft cover, but for an extra fee you can exchange it for a GlacioTex™ Cooling Cover with fibers that help redirect excess heat.

Underneath is a layer of Helix Dynamic Foam that emulates the responsive feel of latex. It’s backed by two layers of Helix Responsive Foam, one that cradles pressure points, and one that provides a firmer feel.

The Dawn’s coil unit has individually wrapped springs that have been reinforced along its long edges. The coils sit on top of a sturdy later of DuraDense foam.

Our Take: The Dawn balances comfort with palpable support. Our reviewers felt that they were resting “on top of” rather than “inside” the mattress.

What We Liked

  • Bouncy as well as firm – Just because this bed is firm doesn’t mean it lacks responsiveness or has no give. Its upper foams lend it a nice amount of bounce.
  • Multiple cooling strategies – The Dawn cools down sleepers with a breathable cover, the airflow around its coils, and foams that avoid heat retention. (If you want extra cooling power, you can upgrade the cover to a GlacioTex™ version.)

Potential Drawbacks

  • Too hard for side sleepers – Side sleepers probably won’t feel cushioned enough by this bed, which was designed with back and stomach sleepers in mind. Lightweight sleepers may also wish for a more pillowy feel.
  • Limited edge support – There’s no added edge support on the top and bottom sides of this bed. You’ll have to upgrade to a Luxe or Elite Helix model for the reinforced coils to encircle the whole perimeter.

Customer Reviews of the Helix Dawn Mattress

The Helix Dawn has an average of 4.4 out of 5 stars on the Helix website. Negative reviews say that the mattress seems to get softer over time, but the majority positive reviews claim the bed is comfortable and has helped with aches and pains.

Why the Nectar Earned Best Memory Foam King-Size Mattress

Years after its launch, Nectar’s original memory foam bed remains one of the reigning champions of the online mattress world. Therefore it’s no surprise that we recommend it if you’re looking for an all-foam, king-sized bed.

It’s an affordable option that, despite its lack of springs, finds a rare harmony between softness and support. Its cushiony surface is a special treat for achy joints even as its denser base foam pushes for proper spine alignment.

What’s the Nectar Mattress Made Of?

The Nectar is 12 inches high and has a top and lower cover with three CertiPUR-US® certified foam layers in between.

The soft upper cover features polyethylene fibers that should help prevent overheating. Underneath is a 2-inch layer of gel memory foam that conforms to your silhouette and cradles sensitive pressure points.

Next is a 3-inch layer of transitional foam that’s a bit bouncier than the foam above, reducing the risk of a “stuck” feeling as you move around in bed.

testing the layers and construction of the nectar mattress
Take a closer look at the Nectar mattress construction

After that is the 7-inch layer of ActiveSupport foam that serves as a firm base.

My Take: If you’re a side or back sleeper with an average build, the Nectar should be a lovely fit for you. It’s priced more affordably than many other king-sized beds on this list, with awesome policies to match.

What I Liked

  • Sensitive sleepers rest easy – The Nectar’s all-foam design gives it exceptional motion isolation. Sharing this king bed with a partner should be a relatively disturbance-free experience.
  • Dreamy policies – Nectar offers a generous 365-night sleep trial and lifetime warranty with your purchase. If the bed doesn’t meet your needs, you can return it without jumping through multiple hoops.

Potential Drawbacks

  • Some sleepers need more support – The Nectar’s positive qualities don’t eclipse the fact that it’s not built for heavier folks or stomach sleepers. Both of these demographics need more lift than this all-foam mattress can give.
  • Cooling doesn’t stand out – I felt perfectly pleasant as I tested the Nectar, but I didn’t notice any active cooling taking place. If you sleep very hot, its temperature-regulating features probably won’t make much of a difference.

Customer Reviews of the Nectar Mattress

With thousands of reviews on Nectar’s website, the Nectar mattress has an average 4.8 out of 5 stars. One common customer complaint about the Nectar mattress is its longer-than-average break-in period, while many customers praise its excellent value and comfort once fully settled.

Why the Bear Star Hybrid Earned Best Cooling King-Size Mattress

The Bear Star Hybrid is often marketed to athletes, but its cooling components don’t discriminate—they should help anyone who tends to sleep hot. At the top of this king-size bed is a cover that boasts temperature-regulating HydroCool® technology, as well as Celliant® fibers that allegedly transform body heat into infrared energy.

In the body of the mattress, cooling foams and individually wrapped coils also help to prevent overheating.

What’s the Bear Star Hybrid Made Of?

The Bear Star Hybrid is a 13-inch mattress equipped with five layers.

The cover of the bed incorporates two high-tech touches: HydroCool® technology for temperature regulation, and Celliant® fibers that may speed up muscle recovery after strenuous activity.

The first comfort layer is Serene Gel Foam that should provide plushness and temperature regulation. Below is a layer of comfort foam that adapts to different body types and sleep positions—a benefit for couples sharing a king-size bed. This layer also serves as a transitional unit between the upper portion of the mattress and the coils below.

Take a closer look at the Bear Star Hybrid mattress construction
The Bear Star Hybrid construction built on 5 layers

The coil unit’s primary purpose is support. This 8-inch innerspring layer should ensure your spine remains well-aligned throughout the night, and stronger coils along the perimeter reinforce the edges of the bed.

Underneath, the base of this bed is a highly-dense foam for added durability.

Our Take: This hybrid has some signature features—most notably its Celliant® cover—that add up to a unique package. Its medium-firm feel should accommodate most couples, even if they have different sleeping preferences, so we dig it as a modern and cool king-size mattress.

What We Liked

  • Noticeably cool – My colleague Stuart found the cover of the Bear Star Hybrid to be “refreshing” and palpably cool-to-the-touch. Combine it with the airflow from the coils and the gel in the first layer of foam, and you’ve got a mattress that really resists the heat.
  • The Celliant® factor – Celliant® is still being studied, but its manufacturers claim that it can hasten muscle recovery after a workout. Ostensibly, it does this by upping bloodflow to the area of your body in contact with the fibers.

Potential Drawbacks

  • A bit firm – The Bear Star Hybrid was given a 6 on our firmness scale, which means it’s medium-firm, but perhaps slightly too hard for lightweight side sleepers. As a hybrid, it has a responsive rather than a “hugging” surface.
  • Iffy edge support – Stuart was unimpressed with the edge support while testing this bed. If you’re ordering a king, though, you may have enough space to negate this as a big concern.

Customer Reviews of the Bear Star Hybrid

Coming in at approximately 4.5 out of 5 stars on Bear’s site, the Bear Star Hybrid has generally positive reviews. Customers praise the Bear Star Hybrid mattress for its excellent cooling properties, however some have found it to be on the firmer side, which might not be suitable for those seeking a softer feel.

Why the Brooklyn Bedding Signature Hybrid Earned Best Cheap King-Size Mattress

As my fellow tester Emma remarked, “the Signature Hybrid mattress is where affordability meets quality.” This king-sized bed can be had for hundreds less than $2,000, making it one of the most affordable king-size mattresses on this list. Our team typifies it as an eminently sensible (if not overly fancy) option.

What’s the Brooklyn Bedding Signature Hybrid Made Of?

The Brooklyn Bedding Signature Hybrid is 11.5 inches tall with five inner layers underneath its cover. You can order it in a Soft, Medium, or Firm feel—the firmness you choose will determine how thick each layer is.

The first layer is a quilted top that allows for some cushion while also preventing long-term sagging or body impressions. It’s followed by a layer of comfort foam that’s designed for both pressure-relief and springy responsiveness.

Next is a layer of VariFlex™ foam that adds support and transitions into the bed’s innerspring unit.

Brooklyn Bedding Signature Hybrid Construction from the lab

There, 8-inch coils flex individually in fabric pockets, and reinforced springs along the sides help the edges stay strong.

Finally, a base layer of high-density foam acts as a long-lasting foundation.

Our Take: “This has all the luxury features that you’re looking for in a hybrid mattress … nice pressure-relieving foams on top, supported by the coils beneath. It doesn’t sacrifice support or pressure relief.” – Mark, Sleep Advisor Mattress Tester

What We Liked

  • Great for combo sleepers – Emma, a joint side and stomach sleeper, complimented this mattress’s springiness: “It’s really bouncy and responsive, which makes it easy for me to flip from my stomach to my side.”
  • Edge support frees up space – If you’re planning on sharing your king-size bed with others, the Brooklyn Bedding Signature Hybrid’s edge support should give you plenty of room. “You can maximize every inch of the surface,” said Emma, “which is ideal if you share a mattress with a partner, kids, pets, whomever.”

Potential Drawbacks

  • Not very soft – Side sleepers may have trouble getting comfortable on this hybrid, as it’s not particularly plush. “If I exclusively slept on my side, I’d probably choose a softer bed,” Emma concluded. However, you can also pay extra to add a pillow top and cooling cover to your mattress.
  • No frills – The Brooklyn Bedding Signature Hybrid is a simple bed, built well. It won’t have lots of fancy bonus features—just everything you need for a supportive, comfy sleeping surface.

Customer Reviews of the Brooklyn Bedding Signature Hybrid

On Brooklyn Bedding’s website, the Signature Hybrid has 4.7 out of 5 stars. This mattress receives praise from customers for its versatility with different firmness options, but some have mentioned that it may produce slight noise when bearing weight.

What is a King-Size Mattress? 

A standard King-size mattress is 76 inches wide and 80 inches long. These dimensions make king beds a full 16 inches wider than Queen beds — they give you more than a foot of added lateral space.

Although these are the typical dimensions of a King-size mattress, there are nuances when it comes to the type of King bed you buy.

What to Look for in a King-Size Mattress 

As the name suggests, King mattresses are large, and they will take up a good bit of space. Therefore, you will want to make sure that your bedroom can accommodate it and any other furniture that you may want to add. 

Once you have established that you have a room that can house this substantial piece of furniture, you will want to decide what type of King bed you want. Although there are now a host of super-sized Kings, such as the Texas King and the Alaska King, we are going to concentrate on three of the most popular: King, California King, and Split King. After you have that narrowed down, you’ll want to consider other important preference-based features.

Types of King Beds

Standard King

A standard King-size mattress measures 76 inches wide and 80 inches long. You may also hear it referred to as an Eastern King. This is the most common incarnation of a King-size bed.

California King

A California King mattress is slightly narrower and longer than a standard King, measuring 72 inches wide and 84 inches long. It’s also known as a Western king, Cali king, or Cal king.

What’s the Difference Between a King and a California King?

A standard King-size mattress is wider than a Californa King, whereas a California King is slightly longer. 

So, why you might buy a California King over a King? Certain sleepers — especially tall ones — appreciate the extra length. Its dimensions may also work better with your bedroom setup. The King vs. California King debate is long and storied, with good arguments on either side.

Split King

A Split King mattress is exactly what it sounds like: a King-size bed, split down the middle into two separate sides.

Split Kings are ideal for couples who want to sleep beside one another but have notably different preferences in terms of comfort. For example, maybe you like a soft mattress, but your partner prefers an extremely firm bed. With a split king, you wouldn’t need to compromise.

Often, a split king will be two Twin XL mattresses lined up side by side. This setup works well with a split adjustable base — sleepers not only get the feel they want from their bed, but they can also manipulate the position of each mattress independently. You can also find some Split California Kings, though they’re a bit tougher to find than standard Split Kings.

Type of Mattress 

From our mattress studio, images of our tested mattresses in different materials

Innerspring Mattresses 

Traditional innerspring beds can use an interconnected coil system, though more recently, many bed-in-a-box brands now use a pocket coil that keeps the bounce while isolating motion. 

Innerspring beds can offer great support, bounce, airflow, and affordability. However, they’re not as great for pressure because they don’t have substantial comfort layers.

Hybrid Mattresses

Hybrid mattresses are a mashup of foam and coils. With upper layers made of foam or latex, sleepers can receive contouring pressure relief, and the durable base layer of coils can allow for better support and easier repositioning. 

The coils also provide airflow, which helps keep the mattress cool. Many hybrid bed manufacturers also use gel-infused foam, aeration, and other cooling technologies to provide additional temperature-regulating properties. The construction and materials used in hybrid mattresses can often make them more expensive than other models.  

Memory Foam Mattresses 

There are a lot of different types of memory foam mattresses out there. Often, these beds have memory foam at the top with firmer poly foam toward the bottom. 

Memory foam mattresses can be excellent for pressure relief, support, and motion isolation. They are also a more affordable option. While memory foam has a reputation for trapping heat, many manufacturers now add cooling features to help offset this.

Latex Mattresses 

Latex mattresses are made out of latex, which is a type of rubber foam. There are typically two types – Talalay and Dunlop latex. These differ in construction but have a very similar feel and quick responsiveness, gently contouring to sleepers’ bodies and cradling their curves.

Latex is temperature-neutral, durable, and great for pressure relief. In the case of naturally-made latex, it’s also eco-friendly. The main downside to latex, though, is its high price point.

Other Considerations When Shopping for a King-Size Mattress 

Sleeping Position 

Julia Forbes testing a mattress for back sleeping
Testing a mattress in the back sleepers position.

Side sleepers typically like a soft bed that can relieve pressure from their hips and shoulders, as these areas put more pressure into a bed over a smaller surface area. 

Back sleepers, on the other hand, usually enjoy something that can help distribute their weight evenly over the surface of the bed. A medium feel often works for these folks as this will fill in the gap between their hips and shoulders without throwing off their alignment.

Stomach sleepers often drift towards a firmer bed. These types of mattresses keep their hips elevated and level with their shoulders. An overly soft bed could cause their hips to dip too low into the mattress.

Combination sleepers need a bed that targets at least several sleeping positions, usually, something with a medium feel and more responsiveness to help them move around.

For more information, see our article on the Best Sleeping Positions.

Weight/Body Type of Sleepers

The dimensions of a King-size bed should work for most body types, but you’ll also need to take your weight and how it will interact with the materials, firmness, and other features into consideration. Many people sleep comfortably on a bed with a medium firmness, but those who are on the lighter side are often more comfortable on softer mattresses as this helps pressure from building up. Meanwhile, heavyweight sleepers will require something with additional support and firmness to help keep their spines aligned.   

Firmness

The firmness of your mattress is going to affect how you sleep. Something overly soft can leave you feeling stuck in bed, while something too firm can feel like concrete.

Beds are usually categorized as Soft, Medium, or Firm, with some variance in between. Certain brands may use different firmness titles, so reach out if you are unsure. For more info, check out our complete mattress firmness guide.

Cooling 

The size of a mattress doesn’t necessarily affect its ability to keep you cool, but before making a major purchase like a King-size bed, you will want to consider its temperature-regulating capabilities. This is because staying cool throughout the night is one of the most important factors when it comes to getting restful and restorative sleep. 

Memory foam is a popular choice for many consumers because of how it cradles your body, but it has a tendency to sleep hot. Fortunately, many manufacturers have taken note of this issue by infusing gel into the foam. Latex is a cooling material and it can be a good choice when it comes to drawing heat away from your body. Additionally, innerspring and hybrid mattresses’ coil units allow air to flow freely.

Motion Isolation 

Co-sleepers have to not only be concerned about their sleeping preferences but also the movements of their partners. If the nocturnal movements of your spouse, child, or pet are transferred from their sleeping area to yours, it can disturb your sleep. 

King-size beds should give you plenty of room to move around, but if your bed doesn’t isolate motion well, the size won’t matter as much. Memory foam and hybrid mattresses both do well at keeping motion from one side of the bed to the other.

Sex 

Sexually active people will have an expanse of real estate to utilize during their intimate moments when sleeping on a King-size bed. However, to make the most out of your space, you will want to consider how the mattress’s materials will support your endeavors. 

Traditional innerspring mattresses are durable and provide great bounce. However, they may not provide enough cushioning, and they can be noisy. Latex is an excellent choice for sexually active folks as it is extremely responsive and allows for ease of movement, but these beds can be expensive. Hybrids are also helpful for this.

Pressure Relief 

Beds that make the aches and pains of the day melt away can bring restorative sleep. That is why pressure relief is important to consider when purchasing your King-size bed. 

The contouring yet supportive nature of memory foam and latex offers incredible pressure relief because the foam cradles around your body and keeps pressure from building up. However, if you’re a fan of the durability of innerspring mattresses, you may want to consider a hybrid model. Hybrids provide more cushioning between you and the metal coils than traditional innerspring beds.  

Edge Support 

How well-supported you are around the perimeter of your bed may not be a major consideration when choosing your new King-size mattress. However, even in a large bed, good edge support is beneficial, particularly to co-sleepers and those with mobility issues. 

Co-sleepers will be able to use the entire bed without feeling that they are falling out of it. Reinforced edges can give those with mobility issues a solid base to get in and out of bed. Memory foam and latex mattresses can be designed with sturdier foams around the edges, whereas innerspring and hybrid beds typically have exemplary edge support by extending their coils or putting stronger ones around the outside of the bed.

Budget 

King beds are one of the largest and most expensive mattresses on the market. Therefore, if you are shopping on a budget you may want to consider smaller sizes. However, if you are set on a King-size mattress, there are more affordable options that can still provide you with a high-quality product. Shopping online can also help you save money on a King-size bed by purchasing directly from the manufacturer.

King-Size Mattress FAQs

How big is a King-size mattress?

A standard King-size mattress is 76 inches in width by 80 inches in length. This means that while many people should fit comfortably on this bed, those who are over 6 feet tall may want to ensure that this bed will give them enough room to stretch out if they choose. California King-size beds provide 4 more inches in length, but their width is 4 inches shorter.

How much does a King-size bed cost?

When purchasing a King-size mattress, you can expect to pay at least around 1,500 to 2,000 dollars for a quality product. That said, there’s a lot of variability in price depending on what you’re looking for in your bed.

When considering the cost of a King-size mattress, you’ll want to weigh your budget against what features are most important to you. Certain luxury models can cost more than 5,000 dollars  Hybrids and latex beds also tend to be more expensive than foam and innerspring beds.

Are there any cheap King-size beds?

King-size mattresses are typically more expensive, so a less expensive model could present huge savings. There are cheaper models out there, but be careful that you are not confusing “cheap” with “affordable.” So you can get the most out of your money, research different brands and materials. That way, you’re sure to find the best budget mattress.

Is a King-size mattress worth the money?

Yes and no; some beds are going to be far more expensive than other brands that sell similar or identical beds. Again, this is where it is important to compare brands to make sure you are getting a fair deal. There are plenty of good King-size mattresses out there that are worth the price tag.

Should I use a King-size mattress topper?

If you are buying a new bed, you may as well buy it right the first time and get what you are looking for in a mattress and not spend additional money on a topper. If you currently have a King mattress and think it needs just a slight adjustment, a quality mattress topper could be a good way to get the feel you want.
