Why You Can Trust Mattress Advisor

We hold ourselves to the highest standards of integrity in our product reviews and other content by incorporating real customer feedback, empirical testing and objective evaluations. Our results and recommendations are never influenced by the commission we may receive from brands, and products we receive are never guaranteed a positive review.

Each mattress we test gets a Mattress Advisor Score, based upon a calculation of human performance testing, material evaluation, ease of purchase/return, customer service and brand integrity. Mattresses undergo a 6-point testing procedure and an 8-point evaluation in our Mattress Lab.

While all mattresses are subjected to the same rigorous, scientific testing process, the heart of our reviews boil down to one question: Would we recommend this mattress to someone we love?

Available in four firmnesses, this mattress has something for just about every kind of sleeper. For the purposes of this article, however, we’ll be focusing on the luxury firm version of the WinkBed, which has a feel that does really well for back sleepers, folks with back pain, and some stomach sleepers.

Made with coils and foam, the hybrid construction of the WinkBed does wonders when it comes to supportiveness, no matter if you have one or two people on your king-size mattress. The added pillow top layer ensures that there’s plenty of cushion to compliment the structure of the base layers.

On top of the wonderful qualities of the WinkBed, each purchase comes with a lifetime warranty. So if you love your WinkBed (and we’re sure you will) you never need to worry about losing it to manufacturing related issues.

The Helix Midnight Luxe is built for durability from the bottom up, starting with the DuraDense Foam Base Layer topped by a layer of 1,000 individually wrapped pocket coils. This foundation helps provide support and stability while the top four layers focus on comfort, pressure relief, and cooling.

This premium hybrid mattress earned high marks for pressure relief and spine alignment in our testing process, helping make it one of our best mattresses for side sleepers. Despite its mostly foam construction, the Midnight Luxe scored 9.5 out of 10 for cooling. Much of the credit goes to the Ultra-cool Premium Pillow Top. 

Still, this mattress isn’t the ideal choice for everyone. Back sleepers and stomach sleepers who are on the heavier side might find its firmness lacking, and couples or people who share their bed with pets should probably consider a mattress with better motion isolation. The price of the king-size model could be a deal-breaker for budget-conscious shoppers.

The 100-night sleep trial puts the Luxe fairly close to the industry average. The limited warranty is good for 15 years and delivery time is 6-10 business days via FedEx.

A luxurious sleeping experience starts with a great mattress, and you’d be hard-pressed to find a better option than the Saatva. A quilted pillow-top, high-density memory foam, tempered steel coils work together to form a mattress that has all the comfort and support that a sleeper could need.

Since you’re shopping for a king-size bed, you may be looking to share it with a partner. Thankfully, the Saatva happens to be one of the most durable mattresses we’ve ever tested. So you can sleep soundly knowing that this mattress has both of your backs.

Another great feature from Saatva is customizability. That is, this mattress comes in three different firmness options: plush, luxury firm, and firm. Whether you’re a larger-than-average person who sleeps on your back or a petite person who switches positions frequently, one of these firmness levels should work for you.

With a better-than-industry-standard 15-year warranty and 180-night sleep trial, there’s little risk in trying the Saatva out for yourself.

Innerspring mattresses provide increased support and durability over the long haul, making them a great option for sleepers of all sizes. The Brooklyn Bedding Signature Hybrid (aka the #bestmattressever) ranks as our top pick in this category. The Brooklyn Signature bed is offered in three levels on the firmness scale, allowing you to customize the feel according to your preference.

The top layer of the Brooklyn Hybrid mattress uses a gel memory foam topper. This cooling gel foam keeps you from overheating while also resisting body impressions, making sure your mattress will last.

Inside the Brooklyn Signature Hybrid are 952 individually encased Ascension coils, designed to minimize sleep disturbance. This makes the mattress an excellent choice for couples, as it will minimize the motion transfer that happens when one person switches positions or gets up in the middle of the night. 

This hybrid mattress also features a layer of TitanFlex memory foam for enhanced responsiveness. This ensures you can easily switch positions throughout the night. With little risk to the shopper and a lot to be gained, it is not hard to guess why the Brooklyn Bedding Signature Hybrid mattress earned a top spot on our list of the best king size mattresses

GhostBed calls its Luxe model “The Coolest Bed in the World” with enough confidence to trademark the phrase. Our testing and review process doesn’t reveal much evidence to contradict their claim. In fact, it scores 9 out of a possible 10 for cooling. 

We’ve honored the GhostBed Luxe as the Mattress Advisor Top-Rated Cooling Mattress of 2021, and it’s earned a regular spot on our list of best mattresses for hot sleepers. The Luxe uses proprietary cooling technology in most of its seven layers, from the surface (Ghost Ice Fabric) to the core (3″ of gel-infused memory foam designed to draw away body heat). 

Coolness isn’t the only area where this mattress stands out. It also tested well for spine alignment and pressure relief, which makes the Luxe a solid choice for people with back pain and most sleep positions. Couples should also take note of its high scores for motion transfer and responsiveness.

Although the king-size GhostBed Luxe is on the pricey side, you should factor in the sleep trial and warranty. You get a 101-night sleep trial with free returns, and the 25-year warranty is more than twice as long as those of many comparable mattresses.

If you are looking for a king size mattress that is both supportive and responsive, the DreamCloud Premier pillow top mattress is an excellent choice. This 15 inch mattress features five durable hybrid layers, including a cashmere-blend EuroTop and a pocketed coil system. 

Rated at a 6.5/10 on the firmness scale, the DreamCloud Premier mattress is a great option for all sleeping positions, as it excels at providing responsive comfort. As an added bonus, the company provides a full 365-day sleep trial.

The DreamCloud Premier mattress is rated at an almost perfect 10/10 in edge support, spinal alignment, and responsiveness. If you sleep as part of a couple, edge support is an important factor as you may find yourself snoozing near the edge of the bed. Responsiveness refers to how easily you can shift positions, and a high rating in this category ensures you won’t feel stuck. Spinal alignment is an important factor for people with back pain as a straight spine keeps away aches and pains. 

This pillow-top mattress is uniquely suited for all body types, including petite sleepers (who may find that mattresses feel firmer to them) as well as heavier sleepers (who may need the added durability of pocketed coils). The DreamCloud Premier king size mattress is a durable, responsive, and supportive option.

King mattresses can really get up there in price, costing anywhere from $2,000 to well over $3,000. The Nectar mattress, on the other hand, costs just $1,099 for a king mattress, but you wouldn’t know it based on the quality.

Scoring an 8.5/10 or above on 10 out of our 14 mattress tests, the Nectar performs as well or better than many of its more expensive competitors. Couples should enjoy the motion isolation that this mattress provides, while side sleepers can sleep more comfortably thanks to the Nectar’s pressure relieving abilities.

All of these wonderful attributes are topped off by the generous 365-night sleep trial and very generous lifetime warranty that Nectar provides their customers.

Stomach sleepers generally have a more difficult time finding a suitable mattress than back or side sleepers. They need something firm, but not too firm; a mattress that will allow their hips and shoulders to sink in just enough, but not so much that their spine gets thrown out of alignment. The Puffy Lux Hybrid is just such a mattress, thanks in large part to its great spine alignment score.

Good scores in cooling and durability mean that the Puffy Lux Hybrid can also help keep you from overheating and hold up under a good deal of stress. So, don’t worry about having too many people on your mattress, the king-sized Puffy Lux Hybrid can handle it.

Puffy provides a generous lifetime warranty with all purchases of the Lux Hybrid.

For those who suffer from back pain, the Casper Hybrid deserves serious consideration in your hunt for a new mattress – it’s one of the best mattresses for back pain that we tested. One of our highest rated hybrid mattresses, the Casper Hybrid was developed after five years of design and testing. This bed features a combination of open-cell foam that contours to your body’s curves, and pocketed coils that provide exceptional bounce. 

This Casper mattress stands out with a special Zoned Support layer that provides targeted support to different areas of the body. It features softer foam around your shoulders to cradle pressure points, and firmer foam around the hips to help with spinal alignment. 

The Casper Hybrid king size mattress is a great choice for side sleepers because of how it cradles your pressure points. It also has an excellent rating in spinal alignment which also makes it a great choice for back and side sleepers

The Casper Hybrid does a terrific job of providing edge support and preventing motion transfer, two important considerations for couples buying a new mattress. Plus, the solid base of pocketed coils ensure durability and responsiveness throughout the night.

There’s more to a mattress than the middle areas that do most of the work. Sleepers who want to feel supported across the entire mattress surface should find a lot to like about the Cocoon Chill Hybrid. As the name suggests, the Chill Hybrid also performs well for cooling, thanks in large part to its Cooling Mattress Cover.

In Mattress Advisor’s testing process, the Chill Hybrid received a score of 8.25 out of 10 for edge support. That level of support bodes well for people who move around in their sleep, or those who just like to spread out. Couples should also appreciate the edge support, in addition to the motion-isolating properties. 

The Chill Hybrid should provide enough pressure relief and spine alignment to support all sleeping types, although combination sleepers might want a mattress with more responsiveness.

The price of a king-size mattress is on the higher side, although not unreasonable for a luxury hybrid. You get a 100-night sleep trial, with free returns, along with a 10-year warranty and free delivery to all 50 states.

King Mattress Buyer’s Guide

When buying a new king mattress, take the time to consider your individual preferences and needs. Do you want a longer bed, or one with more width? What is your primary sleeping position? Are you looking for a cleaner, healthier option? Read on to discover how to find the best king bed for you and your family (pets included).

In this guide, we will cover

Benefits of a King Size Bed

There are many reasons to upgrade to a king size bed. Maybe you and your spouse have been crammed into a full size or a queen size bed for far too long, and you simply need more space. A king size bed provides the luxury of spreading out with ease. 

It is also possible that one partner moves frequently or gets up a lot, disturbing the other partner. A bed with more space allows greater motion isolation, which prevents one partner’s movements from disturbing the other. 

Motion isolation is also important when you share the bed with your children or pets. With the greater size and reduced motion transfer that a king bed offers, you may not even awaken when your little one jumps in bed or when your pup adjusts. A king bed also ensures every member of the family (canine or otherwise) has their own space while sleeping. Whatever your reasons for buying a king bed, the result is likely to be sounder, happier nights of sleep for all. 

King vs California King vs Split King

Once you have decided to upgrade to a king bed, there are several variations you will want to consider. You can purchase a king, a California king or a split king. While most shoppers believe the California king is larger than the king, this is incorrect. 

The king bed is wider than the California king bed, while the California king bed is longer than the king bed. A king bed measures 76” wide by 80” long, and a California king measures 72” wide by 84” long. If you are tall and find that your feet hang off most beds, a California king could be the right option for you. If you frequently have pets or kids sharing your space, the greater width of a king bed may be a better option for your family. 

A split king is another option to consider. If you sleep as part of a couple and find that motion transfer is a big issue, a split king could be the answer to your woes. This type of bed is essentially two twin XL mattresses combined on separate foundations. 

You will experience little to no motion transfer with this bed. This type of mattress is also much easier to move than a king or a California king bed. Some drawbacks to consider when buying a split king are that special bedding may be required, and there is a valley in the middle of the bed which some may not like.

What to Consider When Shopping

Type of Mattress

Innerspring Mattress

Innerspring mattresses are the traditional option that most people are familiar with. They contain an inner coil system that delivers a springy, bouncy feel. They often come with a pillow or euro top for extra comfort. Innerspring mattresses are a good option for those who sleep hot, as they provide great temperature regulation and breathability.
They are also good for couples who may sleep near the edge of the bed. Innerspring mattresses are not ideal for couples who need motion isolation, or side sleepers who need pressure relief.

Memory Foam Mattress

Memory foam mattresses are made of polyurethane and other materials that bolster density and viscosity. They earned their name from the way they contour and “remember” your shape. Memory foam mattresses are ideal for those who want a bed to contour to their body, as well as couples who need motion isolation.
These beds may not work well for those who tend to sleep hot, as they have the potential to hold in heat, or for heavier people, who may require the support of pocketed coils.

Latex Mattress

Latex mattresses can be made entirely of latex or combined with other materials, like memory foam or pocketed coils. Latex mattresses are great for people who want an eco-friendly mattress, as they have the potential to be green (depending on the manufacturing process).
Latex mattresses are also ideal for those who want a long-lasting bed (they can last up to 15 years, which is longer than any other type of mattress). If you prefer to sink into a mattress, latex is not your best bet. These mattresses can also be on the pricey side, so those on a budget may want to look elsewhere.

Hybrid Mattress

Hybrid mattresses are a combination of two materials, typically foam and coils. Their feel and firmness can vary greatly based upon the materials used, but they generally offer the contouring of memory foam with the responsiveness and durability of coils.
Hybrid mattresses are good for those seeking a cooler mattress, as they are generally more breathable than all-foam mattresses, as well as those who want a combination of foam and coils. Hybrid mattresses tend to have a higher price tag so they are not great for those on a budget.

Sleeping Position and Firmness

  • Side sleepers: If you sleep primarily on your side, you put a lot of pressure on your shoulders and hips. When searching for a new mattress, look for one that provides pressure point relief and contours to your body. Side sleepers should also seek a mattress that keeps their spine in alignment and strikes a balance between soft and firm.
  • Stomach sleepers: The rarest sleep position, sleeping on your stomach requires a mattress that keeps the spine in alignment while reducing pressure on the lower back. Stomach sleepers should look for a mattress that is slightly soft on the top, but does not allow sinking. This sleep position should also invest in a durable mattress that will not sag over time. A medium-firmness level is usually the best option for stomach sleepers.
  • Back sleepers: Those who sleep on their backs need a mattress that offers body contouring as well as the support to keep the spine in alignment. How much contouring back sleepers need comes down to personal preference. A medium-firm mattress on the firmness scale is the best option for back sleepers as it provides significant support without being too firm.

Bed Frame

When purchasing a king mattress, it is important to have a foundation that will properly support your new bed. While you should check the requirements of the particular bed you choose, a bed frame can include box springs (that do not sag), a slatted platform, a bunkie board with a box spring, a slatted foundation, or an adjustable base. You can also place your bed on the floor if desired.

Mattress Accessories

When investing in the purchase of a high-quality king mattress, it is important to protect your investment. A mattress protector is an inexpensive way to shield your mattress from damage.
If you want to add more contouring or a pillow top feel, a mattress topper can transform the feel of your mattress without the expense of buying a whole new bed.
If you are looking for a less expensive alternative to a mattress topper, a mattress pad can provide an upgraded feel while protecting your mattress from damage.

Trial Period and Warranty

Almost all of the bed-in-a-box companies include a risk-free trial period. They last an average of 100 nights, and allow you to test out the mattress in your own home. Some companies require you to keep the mattress for at least 30 days. After that, simply contact the company for a free return.
The majority of online mattresses also include a warranty. A 10-year warranty is typical, though some companies offer a lifetime warranty. They generally cover the repair or replacement of the mattress if it has manufacturer’s defects and only apply to the original owner.
