The 10 Best King Mattresses of 2022

How We Chose Our Products

Our team of sleep specialists have reviewed more than 150 mattresses, using proprietary analysis and hands-on testing to establish easy-to-understand scores. In addition to an overall score, we measure subscores for support, edge support, cooling, motion transfer, durability, trial period, and warranty.

Because mattress size isn’t exactly a scientific category, we considered how much each of these products costs for a King, then compared that to the overall score. To ensure that we only included high-quality mattresses, we stuck with beds that scored at least a 3.5 out of 5, with six of them scoring a 4 or higher.

Nectar

The Nectar is an all-foam, memory foam mattress that really offers that classic memory foam experience. Lying down, you should feel yourself slowly sink into this King-size bed. The memory foam will take the shape of your body and make you feel oh so comfortable. Also, while it is a memory foam mattress, the Nectar shouldn’t sleep too hot! The mattress features a breathable cover and cooling gel infusions to help with heat dissipation.

What Makes the Nectar Stand Out?

  • When side sleepers lie down, they should sink into the thick comfort layers and feel the pressure melt away.
  • If you need something even softer and more pressure-relieving, consider the Nectar Premier mattress.
  • If you sleep super-hot, take a look at the Nectar Premier Copper, their mattress with more advanced cooling features.

DreamCloud Premier

When you’re shopping for a new King-size mattress, it’s always a good idea to think about your size and weight. For instance, a lightweight sleeper may not need as much support as an average-weight sleeper. If you’re a heavier person and need a King-size mattress to support you, the DreamCloud Premier could be a great choice. It’s a hybrid mattress that features 8.5″ of individually-wrapped coils, as well as multiple layers of high-density foam.

What Makes the DreamCloud Premier Stand Out?

  • The top foam layers and a cashmere cover help create a plush pillowy experience.
  • There’s a comfortable Euro-top that gives the sleeper a lot of pressure relief and also provides breathability for hot sleepers.
  • We’ve ranked the DreamCloud Premier as one of the best mattresses for heavy people, especially for heavier back and side sleepers. Stomach sleepers, however, might need an even more supportive bed.

Helix Midnight

Hybrid mattresses promise the support of coils at the bottom and the soft comfort of foam right on top. And out of the numerous King-size hybrids we’ve tried, Helix has some of our favorites! The brand offers models of all different firmnesses and feels so, no matter what position you sleep in, Helix should be able to set you up. Our personal favorite King-size hybrid has to be the Helix Midnight.

What Makes the Helix Midnight Stand Out?

  • The Midnight is Helix’s most popular model and should provide just the right balance of comfort and support.
  • Back sleepers, side sleepers, and lovers of memory foam should all be comfortable on this bed.
  • Helix offers Luxe models if you want something more luxurious and cooling.

Saatva

If you want an all-around great King-size mattress with a firmer feel, we have to recommend the Saatva Classic. It’s an innerspring bed that features two sets of coils, as well as a plush pillow-top. You can select from Soft, Luxury Firm, and Firm models (all with a different plushness of pillow-top), but the Luxury Firm is going to have the best balance of comfort and support.

What Makes the Saatva Stand Out?

  • The Luxury Firm Saatva Classic should be an excellent fit for all three sleeping positions.
  • This innerspring mattress has the feel of a nice hotel mattress, and its coils leave plenty of room for airflow.
  • Saatva offers numerous models, including the Saatva Latex Hybrid and Loom & Leaf.

WinkBed

The WinkBed — especially the King-size — is a luxurious hybrid mattress with a traditional innerspring feel. Among its many notable features are tall, supportive coils, zoning, and a plush pillow-top. It’s also available in multiple firmnesses, so you can select from a Softer, Luxury Firm, Firm, or Plus model. The Luxury Firm is their most popular and is a great mattress for combination sleepers — comfortable for back sleepers, side sleepers, stomach sleepers, and anyone who switches between all of these positions.

What Makes the WinkBed Stand Out?

  • We’ve placed the WinkBed on our list of best innerspring mattresses.
  • The Plus is WinkBeds’ mattress that was built with heavy people in mind.
  • Being an innerspring mattress, the WinkBed is good for hot sleepers. It boasts a breathable cover, and the tall coils leave a great deal of room for airflow.

Bear Hybrid

Bear designs its beds for athletes who deal with aches and pains, so it’s no surprise that their hybrid mattress is extremely comfortable. When stretching out on a King-size, sleepers should get a lot of slow-relieving pressure relief from comfort layer of graphite-gel memory foam. The mattress then gets firmer toward the bottom, thanks to an 8″ support layer of quantum edge coils. This balance of comfort and support makes the Bear Hybrid a medium-firm mattress that should especially appeal to back sleepers and combination sleepers.

What Makes the Bear Hybrid Stand Out?

  • A King-size is currently under $2,000.
  • Like other Bear mattresses, the Hybrid has a cover made of Celliant — a material that may assist with blood flow and recovery.
  • Between the Celliant, graphite infusion, and airflow-promoting coils, the Bear Hybrid sleeps cool.

Puffy Royal Hybrid

Side sleepers who are on the hunt for a new King-size mattress want to choose something that will relieve pressure on their shoulders and hips. The Puffy Royal Hybrid accomplishes this with multiple memory foam comfort layers that also have some great cooling features, including gel beads to help dissipate heat.

What Makes the Puffy Royal Hybrid Stand Out?

  • We’ve included the Puffy Royal Hybrid on our roundups of the best mattresses for side sleepers.
  • Even though there’s a coil support layer, the bed shouldn’t feel super bouncy.
  • The Puffy Royal Hybrid also has enough comfort and support for back sleepers.

Casper Original

If you struggle with back pain, you want a mattress that will help keep you in neutral spinal alignment. The Casper helps you do just that with something called Zoned Support in its second layer. It’s a layer of memory foam that’s firmer toward the center and softer at the head and foot of the mattress. The firmer zone provides great lumbar support, while the softer zones provide more comfort. This design is intended to keep you well-aligned in all three sleeping positions.

What Makes the Casper Stand Out?

  • Casper’s AirScape foam helps with heat dissipation.
  • Casper also offers other models with more advanced Zoned Support. If you want something a bit plusher with solid lumbar support, the Casper Nova Hybrid could be a better fit.
  •  If you want the highest-end mattress possible, the Casper Wave Hybrid will be the way to go.

Brooklyn Bedding Signature Hybrid

King mattresses are pricier than other sizes, and if you’re on a tighter budget, Brooklyn Bedding is always a good place to start. The company owns its own factory, so they’re able to cut out the middleman and price their beds lower than competitors. The Brooklyn Bedding Signature Hybrid — outfitted with supportive coils and proprietary foams — is the brand’s most popular mattress, and is priced at just a little over $1,000 after discounts. You can select from Soft, Medium, and Firm models.

What Makes the Brooklyn Bedding Stand Out?

  • The Medium model is our personal favorite and offers comfort and support for all three sleeping positions.
  • The coils promote airflow through the mattress, keeping it breathable.
  • Brooklyn Bedding also offers many other mattress models. Hot sleepers should take a look at the Brooklyn Bedding Aurora, and fans of extra-firm mattresses should consider the Plank mattress.

Leesa Sapira

When you’re overheating, chances are you’re not sleeping much. The Leesa Sapira Hybrid mattress is a great choice for hot sleepers looking to get a king size bed. This mattress has many components to it that will keep you cool.

Starting on the outside, you’ll find a soft, breathable cover that should allow for some airflow. And underneath that, you’ll find a layer of responsive polyfoam that has been ventilated. Foam has been known to trap heat in the past, but because this layer is ventilated, it will promote airflow and keep you from overheating.

Another opportunity for airflow is the sturdy, individually wrapped coils in its support layer. Hybrid mattresses are always great for airflow because the coils are spaced, and have plenty of room between them.

What Makes the Leesa Sapira Hybrid Mattress Stand Out?

  • Hot sleepers who love some foam in their mattress, but worry about it trapping heat, will stay cool on this mattress. The top layer of foam is ventilated for airflow.
  • The presence of coils also gives air an opportunity to easily flow through them, which will cool you off.
  • And if you’re sharing this king-size mattress with a partner, both of you should have enough room and space to stay cool at night.

What Are the Benefits of a King-Size Mattress?

As luxurious as King-size mattresses are, the heftier price tag is enough to make you ask if it’s really worth the cost. Here’s a quick run-down of some of the benefits.

  • They offer loads of space. This won’t come as a surprise: King-size mattresses are big. A standard King-size mattress measures 76 by 80 inches, or approximately 6.3 by 6.6 feet. This means there’s tons of room for sleepers to stretch out and get comfy in every sleep position.
  • There’s room for larger people. Taller and/or heavier people sometimes feel cramped on smaller mattresses. A King-size bed should provide more room for them to sleep comfortably.Best Mattresses for Couples
  • There’s room for couples. If you share your bed with a partner, a King offers more space for both of you to stretch out and find the sleep position that feels most comfortable — without kicking, pushing, pulling away blankets, or otherwise disturbing each other. See our best mattresses for couples for some great options.
  • There’s room for the whole family. If you have kids or pets who like to climb into bed with you, then a King-size mattress can accommodate more people much more comfortably than a smaller bed.
  • They create spatial balance. If you have a large bedroom, a King-size mattress can help fill the space so the room feels more balanced. In contrast, placing a small bed in an enormous room can make the room feel imbalanced and sparse.
  • They create a grand look. Many people love the grand look of a King-size mattress and choose a larger bed for aesthetic reasons.

What Are the Downsides to a King-Size Mattress?

While King-size beds offer a lot of benefits, they can also come with some downsides. Here’s a quick overview of the cons of a King.

  • They take up a lot of space. While bigness is one of the primary benefits of a King-size mattress, it can also be a disadvantage if you have a small bedroom. A King bed can overtake the space — or it may not fit at all.
  • They’re hard to move. Because King-size beds are so large, they’re also extra-heavy. This means it can be difficult to transport them to your home and between rooms.Price Graphic
  • They’re costly. No matter the mattress brand, Kings are more costly than smaller sizes. For some people, buying a King-size bed could stretch their budget or be out of reach financially.
  • They may not look good in certain spaces. Cramming a King-size mattress into a space that’s too small to adequately accommodate it can throw off the visual balance of a room and make it feel more cramped. This is purely a matter of design preferences, of course, but it’s something to consider.

How to Choose the Best King-Size Mattress

Alright, so you’ve decided that a King-size mattress is right for you. You’ve ruled out a Queen-size bed. (If you haven’t, read on below!) You’ve determined which type of mattress and which mattress materials best suits your needs. (More on that below, too!) But before you make a purchase, there are still a few more elements to consider. Here are some important factors to think about as you choose the best King-size mattress for you.

  • Sleeping position: If you’re a back sleeper, a blend of pressure relief and spinal support is usually best (think medium-firm). Side sleepers require softer, more pressure-relieving beds; stomach sleepers require extra-supportive beds; and combination sleepers need a mattress that helps them feel comfortable and supported in multiple positions.
  • Body type: Your body weight and height can have a big influence on the type of mattress that best suits your needs. For instance, extra-tall people might prefer the extra length of a California King, heavier-weight people will probably require a more supportive king mattress in the form of an innerspring or hybrid, and so on.
  • Firmness and pressure relief: If you’re thinking about your preferred sleeping position(s) and body type, this will prompt you to think about the appropriate firmness and the level of pressure relief that you need from a mattress. As noted above, back sleepers tend to require a medium-firm mattress. Side sleepers, on the other hand, usually feel best on a pressure-relieving, softer mattress, and stomach sleepers generally need a firmer mattress.mattress cooling features
  • Temperature regulation: If you tend to sleep hot, make sure to prioritize a mattress that sleeps cool. As a general rule, all-foam beds sleep hotter than innerspring, latex, and hybrid mattresses. Some mattresses include design features for the express purpose of sleeping cool, while others don’t. Learn more in our roundup of best cooling mattresses.
  • Number of sleepers: If you sleep alone, then skip this step. But if you plan to share your King-size mattress with a partner, it’s important to consider how they’ll feel on the bed, too. Think about their preferred sleeping position, their body type, whether they’re prone to sleeping hot, and so on. Make sure you find a mattress that suits both of your needs to ensure you’re both able to sleep soundly for years to come.
  • Durability: Since King-size mattresses are usually a big financial investment, most people want to ensure that investment will last for a long time. This is why it’s important to look for a mattress that’s made with high-quality, long-lasting materials, such as sturdy coils, durable latex, and/or high-density foams. See our best mattresses that won’t sag for some durable options.
  • Edge support: If you share your mattress with a sleeping partner, then edge support is especially important. Strong edge support enables you both to utilize the full surface of the mattress, so you can enjoy all the extra space that you’re paying for with a King-size bed. As a general rule, innerspring, latex, and hybrid mattresses tend to offer stronger edge support than all-foam beds.
  • Company policies: If you’re buying a new mattress, it’s a good idea to purchase from a company that offers a sleep trial. This way, you can test out the mattress at home before committing to it long-term. Also consider the brand’s return, exchange, and refund policies so you don’t encounter any unpleasant surprises down the road.
  • Budget: This is an important factor to consider no matter which size mattress you’re buying. Know your budget before you start shopping so you don’t find the mattress of your dreams only to discover that it’s beyond your price point. Many mattresses list their prices based on smaller sizes first, so make sure you select “King” when you’re price shopping.

The 4 Different Types of King-Size Mattresses

When people picture a King-size bed, they typically imagine a…big bed. But there are actually several varieties under the “King mattress” umbrella. Here’s a quick overview of the different types of King mattresses.

King Mattress

In the mattress world, this term refers to a standard King-size mattress, which gives sleepers an extra 16″ of width compared to a Queen-size bed. It measures 76″ wide by 80″ long. That’s the same width and length that you’d get if you pushed two twin XL mattresses together.

California King

A California King is even longer than a standard King. It’s also a little narrower. It clocks in at 72″ wide and 84″ long. The extra length means California King mattresses are especially well-suited to tall people.

Eastern King Mattress

This term is used interchangeably with “King mattress.” It refers to a mattress that’s the same size as a standard King, or 76″ by 80″.

Split King Mattress

As the name suggests, a split king is a mattress that’s divided into two pieces. Each piece is approximately the size of a twin mattress. Many couples enjoy sleeping on a split king because they’re able to customize each side to their personal preferences. Split king mattresses are sometimes referred to as dual King beds.

How to Decide Between a King vs Queen Mattress

If you’re considering a King-size mattress, then odds are good that you’ve also taken a gander at Queen-size beds. Many people find themselves trying to decide between these two sizes. Here are some factors that can help influence your decision.

  • Bedroom size: This is the quickest way to determine whether a King or a Queen-size mattress might be right for you. When you take measurements, don’t just think about the mattress. It’s also important to consider how much room you’ll have for a bed frame, side tables, dog beds, dressers, general floor space, and so on. If you or your partner use a wheelchair or other mobility device, make sure there’s plenty of room to maneuver.
  • Sleeping situation: If you share a bed with a partner, pet, and/or child, it could be a good idea to upgrade from a Queen-size mattress to a King. If you sleep alone, then you might find ample space on a Queen.
  • Body type: Taller and/or larger people often prefer having a more spacious mattress in the form of a King-size bed. The same goes for couples wherein both partners are on the taller and/or larger side.
  • Design preferences: Finally, it’s helpful to consider your aesthetic preferences. Do you like the grand impression made by a King-size bed? Do you prefer your bed to take up less space in the bedroom? Do you have your eye on a specific bed frame that’s only available in one size? The answers to these and other design questions will inform your decision between a King and Queen mattress.

Top 5 Best Mattress Types for a King-Size Bed

Once you’ve decided that a King is the best mattress size for you, you might be eager to go out and purchase a big mattress. But there’s still one key decision to make: Which mattress type is best? There’s no singular best King mattress type, but there will be a mattress type that best suits your needs. Here’s a quick overview of the different types of mattresses you’ll encounter while hunting for a King bed, plus some of their pros and cons.

Memory Foam

Memory foam is a popular material because it generally offers a lot of pressure relief, contours the body in ways that promote comfort, and has a slow-moving response to pressure. Often, memory foam mattresses layer this material over a base made of high-density polyfoam or (in the case of memory foam hybrids) supportive coils.Memory Foam

Because memory foam tends to be very pressure-relieving, it’s especially popular among side sleepers. It also appeals to folks who enjoy sinking into their mattress (as opposed to sleeping on top of it), and it’s a great option for couples who don’t want to be disturbed by each other’s movements during the night. This material is not without its downsides, however. It’s sometimes too soft to adequately support back and stomach sleepers, it can make it a touch difficult to move around and change positions, and it’s known for trapping heat. These issues can be alleviated, but it all comes down to the construction of a specific mattress.

Innerspring

As you can probably guess from the name, innerspring mattresses use springs (aka coils) in their construction. The coils tend to create a bouncy, responsive, and supportive feel. Mattresses that incorporate coils often sleep relatively cool, because the coils Innerspringsmake space for air to circulate throughout the center of the mattress.

Given that innerspring mattresses tend to be supportive beds, they’re often well-suited to back and stomach sleepers. When paired with a plusher pillow-top, they could also be a sound option for side sleepers. Some possible downsides? They might not be a great match for people who enjoy sinking into their mattress (as opposed to sleeping on top of it), and they can also be pricier than all-foam beds.

Hybrid

Hybrid mattresses generally offer the best of both a foam mattress and an innerspring bed. While every hybrid is different, they always layer a comfort layer over coils. Oftentimes, that comfort layer will be made of memory foam. In some cases, it will be made from polyfoam, latex, or another material.

Hybrids are especially well-suited to people who want the pressure relief of foam without sinking into their mattress. They tend to be simultaneously pressure-relieving and supportive. One possible downside? Hybrids are often more expensive than an all-foam mattress or innerspring beds. They also might not suit people who enjoy sinking in and feeling like they’re enveloped in the mattress.

Latex

While all latex mattresses are made with (you guessed it!) latex, there’s room for a lot of variation in this category. Some beds are made with natural latex, while others are made with synthetic latex. Additionally, the latex can be processed in different ways to create a denser or airier material. Most latex mattresses are fairly bouncy and responsive and do a good job of sleeping cool.Latex Graphic

Many people love latex because it’s naturally cooling and it can offer pressure relief without making it hard to move around. However, some people (particularly side sleepers) may find that latex mattresses don’t offer enough body-contouring for them to sleep comfortably. Latex beds also tend to be more expensive than most other mattress types.

Airbeds

Not to be confused with inflatable air mattresses, airbeds are actually luxury mattresses. They’re made with customizable air chambers that can be adjusted using an app, a remote control, or a manual crank. Adjusting these chambers changes the firmness of the mattress. This means you can alter the firmness every night depending on how you’re feeling or the position you choose to sleep in.

As you can imagine, the main perk of airbeds is that they’re highly customizable. But that comes at a cost. Airbeds are often very expensive, especially in a King-size. They also tend to have thinner comfort layers, so they might not provide enough pressure relief for folks who enjoy a plusher feel.
