Best King Size Mattress

Searching for the best king-size mattress? At 76″ wide by 80″ long, these beds are great for sleepers wanting extra space. Maybe you sleep with a partner and want to spread out, or maybe you’re looking for a larger mattress to balance out a master bedroom. To help you find a bed that makes sense for your lifestyle and preferences, I’ve listed the best king mattresses below. At the bottom of the page, I’ve included the mattresses in a chart so you can compare prices.

Best King Size Mattresses

Our Methodology

We’ve reviewed more than 220 products in our mattress lab, running each one through tests such as pressure-mapping and measuring motion transfer with a seismometer. From there, we give every bed an overall score based on materials, comfort, support, cooling, and edge support. We also factor in brand performance with categories such as value and warranty.

Since mattress size isn’t one of our categories, we looked at how much each of these beds costs for a king, then weighed that against its overall score. In an effort to recommend the highest-quality mattresses, we chose products with a score of 4 out of 5 or higher. Click here to learn more about our methodology.

Helix is known for its line of customizable mattresses, and we’re especially drawn to the hybrid Midnight Luxe. This bed starts with a breathable Tencel cover and includes two more inches of comfort foam than the standard Helix Midnight.  This mattress has zoned construction, so it should be extra soft around the shoulders to prevent stiffness. A medium-firm product, its blend of comfort and support makes it a solid option for back sleepers, side sleepers, and combination sleepers. For those eco-friendly shoppers and hot sleepers out there, the Midnight Luxe uses recycled and breathable materials

Stomach sleepers and heavier sleepers over 250 lb probably won’t find proper support on the Midnight Luxe. These sleepers should check out the firmer Helix Dawn or our roundup of the best mattresses for stomach sleepers.

The DreamCloud Premier has a gel foam comfort layer below a quilted cover and Euro pillow-top, resulting in a super-soft feel, but its pocketed coil support layer and high-density foam base layer mean there’s adequate support. At 15″ tall, the DreamCloud Premier is fit for side and back sleepers wanting extra cushion around their pressure points. Those struggling with back pain should find a lot to love; the bed’s foam fills in the lumbar region and promotes proper spinal alignment. In addition, the DreamCloud Premier offers great motion isolation and edge support, making it a match for couples. Your restless partner shouldn’t disturb you, and you should be able to spread out over the entire mattress.

Strict stomach sleepers probably need a firmer, more supportive bed.

This pillow-top hybrid mattress by WinkBeds is a match made in heaven for couples. It has great edge support, so you can use the entire surface without feeling like its sides might collapse. The WinkBed is also bouncy and supportive, which are nice perks for sex, and the bed’s comfort foams are infused with cooling gels that work to prevent the trapping of body heat. A versatile brand, the WinkBed is available in Softer, Luxury Firm, Firmer, and Plus versions. Back sleepers should feel supported on the Luxury Firm and Firmer models while side sleepers should get the contouring they need from the Softer model. 

The hybrid construction makes the WinkBed a fairly responsive mattress, so it may not be the best fit for those who want the slow-moving feel of memory foam.

A great option for hot sleepers, the Casper uses aerated, open-cell foam in its construction. With breathable materials, the Casper sleeps cooler than most all-foam mattresses. It’s also great for lower back pain; Casper uses a zoned support system, meaning it lifts the hips and aligns them with the lower back. Our favorite part is that its foam layers are CertiPUR-US® Certified, so they’re free of harmful chemicals or heavy metals. 

While back sleepers and combination sleepers should be comfortable on the Casper, strict side sleepers may need something softer and strict stomach sleepers may need something firmer.

The Saatva’s bouncy innerspring construction offers firm support, keeping your spine aligned. Its durable steel coils in the support layer prevent sagging, a factor that can contribute to back pain. Hot sleepers should especially like the breathable innerspring construction. We also love how the Saatva offers three firmness levels (Plush Soft, Firm, and Luxury Firm), so it should work for most sleepers. Those with back pain should opt for the Firm or Luxury Firm.

If you sleep with a partner or pet and are easily disturbed by their movements, consider a mattress with better motion isolation.

With thick layers of gel memory foam, the Nectar offers tons of plush sinkage side sleepers should love. This mattress scored 6 out of 10 on the firmness scale, making it a little softer than medium-firm. So, side sleepers should have lots of pressure relief around the shoulders and hips. If you share the bed with a partner or pet, you’re unlikely to feel their movements because Nectar has excellent motion isolation. Best of all, the Nectar is a great value mattress.

Some reviews say it’s difficult to switch positions on the Nectar, so combination sleepers may need a better match.

This medium-firm mattress combines pressure relief and support for back sleepers. It should keep their spines neutrally aligned, thanks to a foam comfort layer and a support layer with individually encased coils. Quilted with memory foam, this bed is extremely comfy and should give sleepers pressure relief as soon as they lie down. Combination sleepers should also like the bed’s “on top of” feel; the Signature’s comfort layer blends contouring memory foam with responsive latex foam.

The Brooklyn Bedding Signature doesn’t have many lavish features. If you prefer a luxury bed, you may want to look at other options.

A 6 out of 10 on the firmness scale, the Nolah Evolution is a soft mattress with lots of contouring and pressure relief. The plushness comes from the brand’s proprietary AirFoamICE, letting you comfortably sink in the mattress. With breathable foam and airflow-promoting coils at the bottom, the Nolah Evolution is great for hot sleepers. The Nolah Evolution is also adept at relieving hip and shoulder pain, making it an excellent fit for side sleepers. Back sleepers preferring a softer mattress should love the 8” layer of support coils.

Heavy stomach sleepers over 250 lb need a more supportive mattress than the Nolah.

The Layla is a versatile memory foam mattress; it’s flippable, with a soft and a firm side. The soft side is great for side sleepers looking for pressure-relieving sinkage and contouring. The firm side is a nice option for back sleeping memory foam lovers. Also, the Layla is a good choice for couples. Its foam layers cut down on motion transfer, so you shouldn’t feel disturbed by a restless partner. The best part is this mattress costs $1,249 before sales and discounts. 

There isn’t a ton of bounce to the Layla, so heavier folks and anyone who prefers a more responsive mattress will want a different bed.

If you’re a Leesa fan, you’ll love the brand’s Original Hybrid (not to be confused with the Leesa Sapira Hybrid). You’ll be most impressed if you’re a combination sleeper; it has a balanced, “on top of” feel. This means you should easily switch sleeping positions at night without feeling stuck in the material. The balanced hybrid construction helps back and side sleepers feel supported. Also, the Leesa Original Hybrid offers solid motion isolation, so it’s a great pick for couples. 

This mattress is too soft for most stomach sleepers, who need something firmer to achieve adequate support and proper spinal alignment.

Is a King Mattress Worth it?

Take a look at some pros and cons to decide!

King Mattress Pros

  • King mattresses offer more sleeping space, which is especially nice for couples.
  • If you’re a restless sleeper, you’ll have room to toss and turn without disturbing a partner or falling off the bed.
  • Taller or heavier sleepers should appreciate the extra space offered.

King Mattress Cons

  • King size mattresses are more expensive than other mattress sizes. Sheets, bed frames, and other accessories will also be pricier.
  • A king mattress could be too large for a smaller bedroom. For smaller beds, see our top picks for the best queen mattresses.
  • King mattresses are heavier than other sizes, so it may be harder to move around or set up.

King vs California King Mattresses

A standard king size mattress is 76″ wide x 80″ long, so you’re sacrificing some width for extra height on a California king, which is 72″ wide x 84″ long

A California king is one of the longest mattress sizes available, so if your main priority is length, this is the size you’ll want. You can look for a mattress with great edge support (like the Saatva) to compensate for the loss of width. If you prefer extra width or like a more square mattress look, you’ll probably prefer a standard king size mattress.

King vs Split King Mattresses

A look at a split king setup.

If your partner has different sleep preferences, you should consider a split king mattress. A split king is the same size as a traditional king mattress, but it’s made of two twin XL beds. Split kings are great options for couples with different sleep preferences or weights. Each side can be customized to meet your individual sleep needs, so a light side sleeper and a heavy stomach sleeper can share a bed and still get the desired support and pressure relief.

Another reason to consider split kings is they’re compatible with adjustable bases. These beds match with other bed frames too, so they’re still a nice choice even if you prefer a less high-tech frame.

Picking a King Mattress: Buying Considerations

While you can’t go wrong with any of the king mattresses on this list, I’ve included a few tips that could help you choose the best type of mattress for your body type and sleep needs. You can check out our mattress buying guide for more in-depth information.

Mattress Materials

Take a look at my list below to learn about the main mattress types and who they might be best for.

  • Foam mattresses: Foam mattresses can incorporate a variety of foam materials, including memory foam and polyfoam. They include a support layer of dense foam, rather than a layer of coils found in hybrid mattresses. Foam beds can vary in feel, so most sleepers can find a foam mattress that works for them. I’d steer heavier sleepers or those wanting a firmer feel toward hybrid or innerspring beds.
  • Hybrid mattresses: Hybrid mattresses combine foam comfort layers and coil support layers. These mattresses often feel bouncy and responsive. Many different sleepers should find a suitable hybrid mattress, as these beds differ in feel.
  • Latex mattresses: Latex mattresses are made with latex foams. They’re bouncy, naturally cooling, and very durable. Latex is often used in organic mattresses, like the Avocado Green mattress.
  • Innerspring mattresses: This traditional mattress type, often found in brick-and-mortar stores, relies on a steel coil support system. These beds feel bouncy and supportive, and are great for heavy people, combination sleepers, and seniors.

Firmness and Feel

A bed’s feel is one of the most important buying considerations. Beds can range from firm to soft, but depending on your sleeping position and body type you’ll have different firmness needs. Read the list below to learn which is best for you, and see our mattress firmness guide for more in-depth information.

  • Side Sleepers: Side sleepers often prefer a soft mattress with plenty of pressure relief at pain points like the shoulders and hips. Because of this, side sleepers should check out pillow-top and memory foam mattresses.
  • Back Sleepers: These sleepers do best on medium-firm to firm mattresses. They need enough support to keep their hips neutrally aligned with their shoulders, but also benefit from body-contouring around the lower back.
  • Stomach Sleepers: These sleepers need a firm to extra-firm mattress that prevents their hips from sinking into the bed. Bowing at the back can lead to pain over time, so stomach sleepers should find firm support from innerspring and latex mattresses.
  • Combination Sleepers: Combination sleepers do best on medium-firm mattresses offering appropriate support in multiple sleeping positions. These sleepers should consider a responsive mattress to easily change positions throughout the night.
  • Heavy Sleepers (over 250 lb): These folks should find mattresses softer than lightweight or average-weight sleepers. So, they should find firmer mattresses offering lots of support. Our best mattresses for heavy people roundup provides some great options.

Warranty, Shipping, and Sleep Trial

A few other things to consider when buying a new mattress are its warranty, sleep trial period, and shipping costs. Many online mattress brands provide free shipping, and often arrive compressed in a box. Other brands, like Saatva, may offer free white glove delivery, transporting the mattress to your room of choice.

Warranty and trial-period length also weigh into a buying decision. Opt for a mattress with at least a 10-year warranty and a 100-night trial. Some companies include lifetime warranties and year-long sleep trials, so take a look at company policies before deciding on a new bed. To make sure you’ve got the best deal possible, see my picks for the best mattresses for the money.

FAQ

Are king mattresses square?

No, king mattresses are rectangular at 76" x 80".

Are king mattresses better for couples?

It depends on your preferences! King mattresses are larger, so heavier couples or couples who like to spread out may prefer the additional space.

Do all king mattresses have a ridge in the middle?

A ridge, or hump, commonly develops in the middle of king mattresses because it’s uncommon for solo sleepers or couples to sleep in the center of these large beds. To avoid a “king’s ridge,” you can make it a point to spend time in the center of your mattress while awake, add a topper, or choose a solid foundation or box spring with a center support beam.

Is there a bed size bigger than a king?

Yes, there are a few larger bed sizes. Alaskan king mattresses and Texan king mattresses are 8" to 32" wider than a standard, or Eastern, king mattress. And Emperor size mattresses are 80" x 80", making them the mattresses with the largest surface area on the market today.
