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; this is just one of the reasons why the WinkBed is one of the best firm mattresses. The added pillow top layer ensures that there’s plenty of cushion to compliment the structure of its 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.

If you’re looking for a king size mattress that’s both supportive and responsive, the DreamCloud Premier pillow top mattress is an excellent choice. This 14-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. The DreamCloud Premier 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 can support most 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). As a bonus, the company provides a full 365-day sleep trial.

King mattresses can really get up there in price, costing anywhere from $2,000 to well over $3,000. The original Nectar mattress, on the other hand, costs just $1,199 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 as or better than many of its more expensive competitors. Couples should enjoy the motion isolation that this mattress provides, thanks to its 8.5/10 motion transfer score. Side sleepers can rest more comfortably thanks to the Nectar’s pressure-relieving abilities. Multiple layers of memory foam help the Nectar earn an 8.5/10 score for pressure relief.

The only performance categories where the Nectar disappoints are spine alignment and cooling, where it receives identical 7.5/10 scores (potential red flags for people with back pain and people who sleep hot). Balance those against its many positive attributes, which also include a generous 365-night sleep trial and lifetime warranty.

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.

Anyone who’s ever woken up feeling drained after a night of tossing and turning can appreciate the value of a highly responsive mattress like the Nolah Signature 12″. Responsiveness is the quality that prevents a mattress from feeling stiff, and an unresponsive bed can be particularly troublesome for restless sleepers.

Fortunately for them, the Nolah Signature 12″ offers an answer. This AirFoam bed scores an outstanding 9.5/10 for responsiveness in the Mattress Advisor sleep lab, where reviewers put mattresses to the test in a wide range of performance categories. That score means the Nolah Signature 12″ responds unusually well to the sleeper’s movements.

Many combination sleepers will benefit from the Nolah’s responsiveness as they change positions in the night, although side sleepers might see the best results thanks to a 9.25/10 pressure relief score. The Nolah Signature 12″ also has appeals for hot sleepers (8/10 cooling score). Seniors, however, might be disappointed with its edge support (6.6/10 score).

A king-size Nolah Signature 12″ has a regular price close to $1,800, not counting promotions or holiday sale discounts. Still, it does come with a lifetime limited warranty and free delivery. You also get a 120-night sleep trial.

Finding a king-sized mattress that can keep you cool is a must for those who sleep hot or live in a humid location. The Bear Original incorporates several cooling properties in an effort to give you the optimal sleep environment. It starts with an open-cell response foam that promotes breathability and is cool to the touch. Bear also infuses its foam with graphite and uses a Celliant cover to absorb body heat.

The Bear Original scored high (9/10) for responsiveness, making it an easy mattress to change positions on. Seniors or those who use the edge of their bed a lot will appreciate its 8.5/10 score for edge support. Plus, it also scored 8.5/10 for spine alignment, meaning you’re less likely to wake up with an aching back.

A king-size model for the Bear Original starts at just under $1,250. Bear also offers financing through Affirm and monthly payment options with Splitit. Every mattress comes with a 120-night sleep trial, free shipping, and a lifetime warranty.

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 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.

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.

Thanks to a lifetime warranty and 365-night sleep trial, there’s little risk in trying the Saatva out for yourself.

For those who suffer from back pain, the Casper Hybrid deserves serious consideration. 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.

Medium-Firm - 6/10

trial period

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 back, hips and shoulders can’t maintain a healthy alignment as they sleep. The Puffy Lux Hybrid is just such a mattress, thanks in large part to its 6/10 firmness rating and 8/10 Mattress Advisor score for spine alignment. The Contour-Adapt Coil Base makes up its core layer, topped by three layers of cooling and body-contouring foam.

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 sharing the mattress with your sleep partner, your kids, or even your pets. The king-sized Puffy Lux Hybrid can handle it.

Puffy provides a generous lifetime warranty with all mattress purchases, as well as a 101-night sleep trial for you to see if the Puffy Lux Hybrid is the mattress for you.

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:

Who Should Get a King Mattress?

Although queen is the most popular mattress size, you might benefit more from king-size instead. While standard queen and king sizes are both 80 inches in length, a king is 16 inches wider (76″ vs. 60″). People who should consider a king mattress include:

  • Heavy people (more width for people with larger frames)
  • People or couples who are taller than average (more room to extend your arms and legs)
  • Families with children, pets, or both who sleep in the same bed (more room on chilly and stormy nights)
  • Combination sleepers (more room to change sleeping positions)
  • Couples with one or more restless sleepers (more room for tossing and turning)

A king mattress might cost $100 to $200 more than a queen, depending on the brand and model, but certain people might find the extra 1 foot and 4 inches of width well worth the cost.

King vs California King vs Split King

Once you’ve 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.

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 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 breathability.
    They are also good for couples who may sleep near the edge of the bed. Innerspring mattresses are not ideal for pressure relief.
  • 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 great for providing pressure relief, and limiting motion transfer. 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 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 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 support and durability of coils. Hybrid mattresses are good for those seeking a cooler mattress, as they are generally more breathable than all-foam mattresses. They 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 (and least healthy) 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.

Price

King mattresses are more expensive due to their larger size. Doing your own research can allow you to find a quality mattress in your budget that suits your sleeping needs. Knowing how much you’re willing to spend can help you frame you research around certain brands or particular features.

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 typically last 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 15-year, 20-year, or lifetime warranties. They generally cover the repair or replacement of the mattress if it has manufacturer’s defects and only apply to the original owner.
