Helix is known for its line of customizable mattresses, and we’re especially drawn to the hybrid Midnight Luxe. It’s zoned for pressure relief, which means it will be extra soft around the shoulders to prevent stiffness. 

Pros

  • The Midnight Luxe starts off with a breathable Tencel cover. This recycled material is a nice perk for both eco-friendly shoppers and hot sleepers.
  • It also includes two extra inches of comfort foam, which makes it even better than the standard Helix Midnight for anyone looking for plush pressure relief.
  • The mattress is medium firm, making it a great choice for combination sleepers. It’s contouring should also be appealing to side sleepers.

Cons

  • It’s unlikely that heavier sleepers over 250 pounds will find the support they need on the Midnight Luxe.
  • Likewise, stomach sleepers will probably find the bed to be too soft. They’re better off checking out the firmer Helix Dawn or maybe taking a look at our roundup of best mattresses for stomach sleepers.

If you struggle with back pain, the Saatva’s bouncy innerspring construction offers firm support, which could help keep your spine in a straight line. The durable steel coils in the support layer also prevent sagging, a factor that can contribute to back pain.

Pros

  • Saatva offers its classic mattress in three firmness levels (Plush Soft, Firm, and Luxury Firm), so most sleepers should be able to find a model that works for them. Folks with back pain should opt for either the Firm or Luxury Firm.
  • Stomach sleepers should be comfortable on the Saatva, as it has plenty of support from the coils. Combination sleepers should also find the bed responsive enough for them to change positions at night. 
  • The coils of the Saatva allow for plenty of airflow, so the mattress should sleep cool.

Cons

  • The Saatva doesn’t have the best motion transfer, so if you sleep with a partner or pet and are easily disturbed by their movements, this might not be the mattress for you.
  • Side sleepers will probably be uncomfortable on the Firm and Luxury Firm models. However, they might enjoy the Plush Soft, which has a lot more contouring for their joints.

This high-quality king mattress is worth the investment. You can learn more about it in our full Saatva mattress review.

The Layla’s bed-in-a-box mattress stands out for being flippable, with both a soft and a firm side. The soft side is a great option for side sleepers looking for pressure-relieving sinkage and body contouring. The firm side, on the other hand, could be a nice option for back sleepers who also enjoy the body-contouring feel of memory foam.

Pros

  • The Layla is also a good choice for couples. Its memory foam layers cut down on motion transfer, meaning you won’t feel disturbed by a restless partner on this bed.
  • Price is something to keep in mind when purchasing any king size bed, as they tend to be more expensive because of their size. The Layla is currently priced at $1,099, making it fairly affordable. 
  • Anyone suffering from hip pain will probably need a softer bed, and the Layla should fit the bill.

Cons

  • There isn’t a ton of bounce to the Layla, which shouldn’t be a problem for anyone who enjoys the soft, slow-moving sensation of memory foam. But heavier folks and anyone who prefers a more responsive mattress will probably need a different bed.

WinkBeds’ pillow-top hybrid mattress has great edge support, meaning that couples can use the entire surface area of this mattress without feeling like its sides might collapse. It’s also bouncy and supportive, which are nice perks for sex.

Pros

  • The bed’s comfort foams are infused with cooling gels that work to prevent the trapping of body heat. This helps to dissipate the added body heat you get from having two sleepers on a mattress.
  • The WinkBed is available in a Softer, Luxury Firm, Firmer, and Plus model for heavier folks.
  • 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. 

Cons

  • The hybrid construction makes the WinkBed a fairly responsive bed, so it might not be the best fit for anyone who wants the slow-moving feel of memory foam.

Built with thick layers of gel memory foam, the Nectar offers tons of plush sinkage that side sleepers should appreciate. They should get all of the pressure relief they need from this bed.

Pros

  • The Nectar is a great value bed. Like most foam beds, it’s one of the less pricey options on this list.
  • It scored a 6/10 on the firmness scale, making this a fairly soft mattress.
  • Being an all-foam bed, the Nectar has excellent motion isolation. If you share the bed with a partner or pet, you’re unlikely to feel their movements.

Cons

  • Some reviews have said that it’s very difficult to switch positions on the Nectar, so it might not be the best match for combination sleepers.

This medium-firm mattress offers a nice mix of pressure relief and support for back sleepers. It should keep their spines neutrally aligned (read: straight) while they’re lying down.

Pros

  • The all-foam Leesa uses a breathable foam in its top layer, which means the bed should sleep nice and cool.
  • At a 7/10 on the firmness scale, the Leesa is just a hair above medium firm, so it should be responsive enough for combination sleepers.
  • The bed’s foundation layer is built from six inches of high-density poly foam, contributing to its overall firmness.  

Cons

  • The Leesa doesn’t have great edge support, which tends to be the case with many foam beds.

Combination sleepers usually need a responsive bed that makes it easy to change positions. The Bear fits this bill with a double polyfoam construction that still offers a bit of nice body-contouring for light- and average-weight back sleepers.

Pros

  • The bed is topped with a cover made of Celliant, a material that some people believe promotes blood flow. This makes the Bear popular among athletes and other folks dealing with recovery.
  • There’s a considerable amount of support here for back and stomach sleepers, who often need a bed that keeps their hips lifted and in line with their shoulders.
  • The Bear is built with temperature regulation in mind. Its cooling cover and graphite-infused foams should keep you sleeping cool throughout the night. 

Cons

  • Side sleepers may not be comfortable on the Bear’s medium firmness and should seek out a softer bed.
  • On the other side of the coin, stomach sleepers may find the bed to be too soft and might need something more supportive.

The DreamCloud Premier has a gel foam comfort layer below a quilted cover and euro top, so it has a super soft feel. But its pocketed coil support layer and high-density foam base layer mean there’s still a good amount of support. 

Pros

  • At 15 inches tall, I’d recommend the DreamCloud Premier to side and back sleepers looking for extra cushion around their pressure points.
  • The bed’s foam fills in the lumbar region, which should appeal to folks struggling with back pain.
  • The DreamCloud also offers great motion isolation and edge support, so it could be a nice option for couples. You won’t feel overly disturbed by a restless partner, and you’ll be able to spread out over the entire mattress.

Cons

  • Strict stomach sleepers are probably going to need a bed with more firmness and support.

If you’re looking to score king mattress benefits without the king mattress price tag, Sealy’s Cocoon Chill mattress might be the perfect fit for you. Sleepopolis has tested the firm version of the Cocoon Chill, which treats sleepers to a two-inch memory foam layer. 

Pros

  • The firm version of the Cocoon Chill could be a nice match for back sleepers looking for a bit of body-contouring.
  • Sealy also offers a soft version of this mattress that might be a nice fit for side sleepers.
  • Like the name suggests, the Cocoon Chill sleeps cool. It has a breathable cover that works to diffuse any trapped body heat.

Cons

  • Stomach sleepers who need a thicker type of support will probably need a firmer bed.
  • Heavier sleepers should also look elsewhere and might find a better fit on our list of best mattresses for heavy people.

For anyone who sleeps hot, the Casper uses aerated, open-cell foam in its construction to encourage breathability. You should be cool and comfortable while resting on this bed.

Pros

  • The Casper uses a zoned support system, which means it offers a little extra lift around the hips and lower back. This might be a nice way to help alleviate lower back pain for some sleepers.
  • Another perk of the Casper is that its layers of foam are all CertiPUR-US® Certified, meaning they’re free of any harmful chemicals or heavy metals.
  • The Casper has sold edge support, which is a pleasant surprise for an all-foam bed. 

Cons

  • 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.

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 below that could help you choose the best type of mattress for your body type and sleep needs. You can also check out our mattress buying guide for more in-depth information.

Mattress Materials

Latex mattress construction

You should choose your mattress type based on your body type and preferred sleeping position. Take a look at my list below to learn a little about the main mattress types and who they might be best for.

  • Foam mattresses  Foam mattresses can be made out of a variety of foam materials, including memory foam and polyfoam. These beds are made with a layer of support foam that supports the sleeper (rather than a layer of support coils). These beds can vary in feel, so most sleepers can find a foam mattress that works for them. However, I’d steer heavier sleepers or folks looking for a lot of durability towards hybrid or innerspring beds.
  • Hybrid mattresses Hybrid mattresses are made with a combination of foam comfort layers and coil support layers. These mattresses often feel bouncy and responsive. Many different sleepers should be able to find a hybrid mattress that works for them, as these beds vary quite a bit 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. I’d recommend latex mattresses to hot sleepers who enjoy springy support.
  • Innerspring mattresses This traditional mattress type relies on a steel coil support system. Most classic brands you’d find in brick-and-mortar stores make innerspring beds. These beds feel bouncy and supportive, and are great options for heavy people, combination sleepers, and seniors.

Firmness and Feel

How a bed feels is one of the most important buying considerations for any new mattress. Beds can range from firm to soft, but depending on your sleeping position and body type you’ll have different firmness needs. Take a look at the list below to learn which feel is best for you. And check out our mattress firmness guide for more in-depth information about choosing a mattress firmness level.

  • Side Sleepers — Side sleepers normally do best on a soft mattress that offers plenty of pressure relief around their shoulders and hips. It’s common for these folks to feel sore in these areas when they sleep on a firmer bed. I’d recommend these folks 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 can also benefit from some 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 pay special attention to finding firm support. I’d recommend these folks check out latex and innerspring mattresses.
  • Combination Sleepers — Combination sleepers often do best on medium-firm mattresses that offer appropriate support in multiple sleeping positions. These sleepers’ primary concern should be finding a responsive mattress that makes it easy to change positions throughout the night.
  • Heavy Sleepers (over 250 lbs) — I wanted to include a special note about heavier sleepers here, because these folks will often find mattresses softer than light or average-weight sleepers. Because of that, I’d recommend they look for firmer mattresses that offer a lot of durable support. Our best mattresses for heavy people roundup might help these folks find a good fit for their needs.

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. A lot of online mattress brands offer free shipping, and mattresses will often arrive compressed in a box. Other brands, like Saatva, may offer free white glove delivery, which means they’ll deliver the mattress to your room of choice.

Warranty and trial-period length can also weigh into a buying decision. I’d recommend opting for a mattress with at least a 10-year warranty and a 100-night trial, if not longer. Some companies offer lifetime warranties and year-long sleep trials, so definitely take a look at company policies before deciding on a new bed. If you want to make sure you are getting the most band for your buck check out my picks for the best mattresses for the money.

King vs California King Mattresses

We get a lot of questions here at Sleepopolis about the difference between a king and California king bed. A standard king size mattress is 76 inches wide x 80 inches long, while a California king is 72 inches wide x 84 inches long. So you’re sacrificing some width for extra height on a California king. If you’re especially tall, you might prefer these dimensions.

A California king is the longest mattress size available, so if your main priority is mattress length, this is definitely the size you’ll want to opt for. Additionally, you can look for a mattress with great edge support (like the Saatva), to compensate a little for the loss of width. On the other hand, 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

Loom & Leaf foundation - King size (split Twin XL's)
A look at a split king setup.

If you sleep with a partner who has very different sleep preferences from you, you may want to 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 mattresses placed side by side. Split kings are great options for couples with different sleep preferences, or couples of different 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 support and pressure relief they each need.

Split kings are also compatible with adjustable bases, which could be another reason to consider this mattress option. These beds are compatible with other bed frames too, so are still a nice choice even if you prefer a less high-tech frame.

Is a King Mattress Worth it?

So is a King mattress a sound investment? Take a look at some of the pros and cons of these beds to decide!

King Mattress Pros

  • King mattresses offer more sleeping space, which can be especially nice for couples.
  • If you’re a restless sleeper, you’ll have plenty of room to toss and turn on a king without disturbing a partner or falling off the bed.
  • Taller or heavier sleepers might really appreciate the extra space a king mattress offers, especially if they often wake up with their feet hanging off the side of the bed.

King Mattress Cons

  • King size mattresses are significantly more expensive than other mattress sizes. Sheets, bed frames, and other accessories will also be pricier, so cost could be a deterrent for many people.
  • If you have a smaller bedroom, a king mattress could be too large for your space.
  • King mattresses are heavier than other mattress sizes, so may be harder to move, especially if you don’t have help.

FAQ

Are king mattresses square?

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

Are king mattresses better for couples?

It depends on your preferences! King mattresses are larger, so couples who like to spread out may prefer the additional space. Heavier couples might also appreciate the additional space and support a king size bed offers.

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 for your mattress.

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 inches wider than a standard, or Eastern, king mattress. And Emperor size mattresses are 80 x 80 inches, making them the mattresses with the largest surface area on the market today.
