If you’re looking for a mattress that helps relieve pressure along sensitive parts of the body, the Helix Midnight might just fit the bill—and at a reasonable price, too. As the best-selling mattress in the Helix line, the Helix Midnight is a medium-firm mattress that’s great for lightweight and average-weight side sleepers who want extra pressure relief and weight distribution. The top layers of the mattress are made from Helix’s Memory Plus foam and responsive transition foam. These two layers work in tandem to help relieve pressure buildup. A robust layer of individually wrapped coils makes up the base of the mattress, keeping slee0pers from sinking too far into the comfort materials above.
The mattress didn’t score well on its responsiveness, because it’s built for pressure relief and contouring more than ease of movement. However, it’s still a solid choice for couples because of its durability and motion isolation. Hybrid mattresses are generally built to be a long-lasting investment, and the Midnight is no exception. It also scored well on our motion isolation test.
If you have an eye for luxury, you should consider taking a look at the upgraded version of the Helix Midnight: the Helix Midnight Luxe. The Luxe adds extra layers of foam for added support and comfort. That said, we find the standard Helix Midnight to be an excellent mattress for pressure relief at a more accessible price point.

Couples usually consider cost, motion isolation, and firmness level when shopping for a new mattress. The Nectar is a strong contender in each of these areas. It’s a medium-firm mattress that has great motion isolation and more affordable pricing than similar quality beds in the market.
Nectar goes beyond expectations by using high-quality gel memory foam with a “universal firmness level.” Since couples often have different firmness preferences, the medium-firm feel of the Nectar is a good compromise. It suits both back and side sleepers, though stomach sleepers may want a firmer mattress to prevent too much sinkage around their lower back.
The memory foam layers also trap movement at its source, which cuts down on motion transfer that could otherwise cause sleep disruptions. Plus, couples who are fans of memory foam should fall in love with the cooling abilities of the Nectar. For a memory foam mattress, the Nectar does a great job of dissipating heat, and its gel memory foam feels cool to the touch. And as if they haven’t been generous enough already, every Nectar mattress comes with a 365-night sleep trial, a lifetime warranty, and free shipping in the contiguous U.S.

With one look at the DreamCloud mattress, it’s evident that the bed is built for a King: pun intended! Back and stomach combination sleepers should feel especially comfortable on the DreamCloud mattress because of its medium-firm feel. This creates a balance between comfort and support that’s ideal for these sleeping positions. Additionally, this mattress has a perfect 5/5 score for responsiveness, which means that combination sleepers should be able to change positions without sinking too much into the bed.
While some side sleepers might not find the bed to be soft enough for their liking, hot sleepers should appreciate the bed’s thick layer of breathable coils. The mattress also features gel-infused foam, which should relieve pressure and keep you from overheating at night.
In terms of the qualities we like to see in a King mattress, our testing results showed that not only is the mattress durable, but it could even last you up to a decade. Additionally, we think there’s a lot of strength in the DreamCloud motion isolation capabilities, so you and your partner shouldn’t disturb each other while moving around in the middle of the night. With a generous 365-day trial and a lifetime warranty to top it off, what’s not to love?

We’re still blown away by the fact that companies can fit a massive King size mattress into a tiny, manageable box. Cutting those boxes open in our mattress lab and watching the full product expand to its final form never gets old. Honestly, that experience alone is worth the price of the product, but we think its durability also makes it a long-lasting investment. If you’re willing to spend, then we recommend you check out the WinkBed mattress.
The WinkBed mattress is our top pick for the best King size bed-in-a-box. It measures a mighty 14” from base to cover, and contains a gel-infused cooling layer along with a coil base layer. It also features a hybrid construction that has more of a traditional innerspring mattress feel, while still providing a good amount of cushion throughout its memory foam layers.
Regardless of which position you sleep in, the WinkBed has you covered. There are multiple firmness options: sleepers can go with the softer option for maximum comfort, and for back and stomach sleepers (who need extra support) there are the luxury firm and firm versions. It’s also one of our best mattresses for couples, because although we did see quite a bit of motion transfer, the WinkBed has excellent edge support, responsiveness for ease of movement, and cooling properties. Its breathable foam and coil design allows for sufficient airflow that will keep you cool throughout the night.

The Puffy mattress is a great fit for King size mattress shoppers who prefer the soft, doughy feel of memory foam. As a memory foam mattress, the Puffy provides excellent pressure relief for side sleepers. It’s made with three layers of foam that combine for a medium-firm feel. This firmness level strikes a popular balance between cushioning comfort and support.
We recommend it to those with lightweight (< 130 lbs) and average-weight (130–230 lbs) body types, especially side sleepers. It’s probably not durable enough or supportive enough for most stomach sleepers and those weighing over 230 lbs. We also think that it has many of the features one should look for in a King, such as ease of movement from its responsive foam feel and excellent motion isolation.
While many King size mattresses run into the $2,000’s, the Puffy stays under $1,500—and often, the price is even lower thanks to seasonal discounts. When you buy a new Puffy mattress, you get free shipping, free returns, an industry standard 101-night sleep trial, and an industry topping Lifetime warranty.

If you’re on the market for a King mattress, you probably understand that you’ll have to spend quite a bit of money. With a purchase that big, why not spend a little bit extra to ensure you’re getting the best of the best? The King sized Nolah Evolution delivers dependable comfort, support, and above all, luxury.
The $2,000+ price tag of this mattress may give you pause at first, but the steep cost makes sense when you consider the quality of construction and materials that the Nolah Evolution employs. With layers of proprietary foam, a base of HDMax Eco support coils and orthopedic support foam, and a reinforced perimeter, the hybrid build of this mattress provides that hotel-bed feel that so many people love.
Plus, since the Nolah Evolution scored so high on our durability (5/5), motion isolation (4/5), and temperature control (4/5) tests, you can share your King mattress with a partner and not worry about damaging its structural integrity, disturbing one another, or overheating. The icing on the King sized cake? The Nolah Evolution comes with a lifetime warranty, so you can rest assured that the company fully stands behind the caliber of their product.

We recommend this mattress for the following sleeper types: Financing options are available for this mattress.

The Casper mattress is an excellent option for memory foam lovers looking to upgrade to a King size bed. It’s the original mattress-in-a-box, and though there have been dozens to follow suit, it’s still one of our favorites.
We think that the original Casper mattress is best for lightweight (< 130 lbs) and average-weight sleepers (130–230 lbs). Coming in right around a 6/10 on the firmness scale, it has a medium-firm feel that’s compatible with a wide range of sleepers. In addition to the cozy, conforming feel of memory foam, the Casper is responsive—meaning it doesn’t “trap” sleepers in its foam layers. This should be a great feature for combination sleepers, or those who change positions throughout the night.
Since couples are usually the ones shopping for King size beds, we can’t skip the Casper’s high marks for durability and motion isolation. The mattress’s foam core is thick and supportive, making it a solid long-term investment. Additionally, the Casper’s dense foam layers keep the movements of one sleeper from reverberating across the bed’s surface. So, if your partner restlessly tosses throughout the night, you’ll no longer have to worry about getting jostled out of your deep sleep.

I guess you could call the Saatva Classic the king of innerspring King size mattresses. It’s a traditional innerspring mattress that’s big on both comfort and support. Additionally, the Saatva’s customizability is there to make you feel like royalty. You can choose from the following firmness options: Plush Soft, Luxury Firm, and Firm.
The Saatva contains a low-gauge Bonnell coil support system, which is a fancy way of saying its coils will keep you stable and lifted on top of the mattress, allowing ease of movement. These coils can withstand high levels of compression without shifting. Not only that, but the Saatva is topped with a plush pillow top layer that provides more added comfort than you’ll find in most innerspring options. As such, the Saatva takes from the best of both worlds: it has the support, response, and durability of an innerspring mattress, but also the conforming pressure relief of foam or hybrid mattresses. And, though it’s responsive and bouncy as an innerspring, we also think that it does a good job at absorbing motion, so neither you nor your partner should feel each other move around during the night.
Saatva prices their mattresses on the higher end of the scale, but the quality materials, construction, and customer experience are nothing short of luxurious. Buying the Saatva Classic in a King size just maximizes the surface area of this luxury, and we think you’ll want as much of it as you can get!

Bear mattresses are made with athletes in mind. If you’re looking for a King mattress to aid in your recovery and help you get an excellent night’s sleep before a big competition, be sure to check out the Bear Hybrid. It boasts a feel that’s both pressure-relieving and responsive, making it ideal for back sleepers of all body types, lightweight to average-weight stomach sleepers, and combination sleepers. Side sleepers will likely want a softer mattress.
With the Bear Hybrid’s focus on athletes comes a number of features relevant to rest and recovery. Hot sleepers should fall in love with the mattress’s two cooling layers; the Celliant fiber top and the gel-infused foam assist with breathability. It’s also important to note that the hand-quilted Celliant fiber top is designed to increase oxygenation and assist with muscle recovery through the night.
Athletes who sleep with a partner should also enjoy the Bear Hybrid. While many hybrids struggle to score high in motion isolation, the Bear Hybrid absorbs motion well, so partners shouldn’t disturb each other while tossing and turning at night. This bed is also great for couples because of its excellent edge support, which means that you should be able to utilize the full surface area of the mattress. As an added bonus, the great edge support is an indicator of durability.

The Brooklyn Bedding Aurora mattress comes in three firmness levels—soft (5/10), medium (6.5/10), and firm (8/10). With multiple firmness options, it can accommodate most sleepers regardless of their sleep position. Additionally, the different firmness options can cater to different body types.
Based on our lab results with the medium version, we feel we have some good recommendations in terms of which mattress to choose based on one’s sleep position and body type. Combination sleepers should overall do well on this mattress because it tested high for responsiveness, meaning that the Aurora should allow for ease of movement. Also, our team thinks the medium and firm versions of this mattress should be great for back sleepers of all weights. As for side sleepers, we recommend that light and average weight sleepers opt for the soft bed, and heavier sleepers test out the medium bed. Finally, since stomach sleepers generally require a mattress with more support, we suggest that light and average-weight sleepers stick with the medium mattress, while heavier sleepers might be better off with the firm mattress.
As for couples, if you sleep with a partner who wakes up easily, the Brooklyn Bedding Aurora’s motion isolation might not be for you. However, it is an extremely durable mattress with over 1,000 pocketed coils, and should last between seven and 10 years. Again, while it’s ultimately up to you to decide which firmness option is best, that is part of the beauty in having multiple firmness options. It can give a more personalized experience, and an overall better sleep. Who wouldn’t want that?

King Size Mattress Considerations
Here’s an overview of purchasing considerations and factors when buying a King size mattress:
- Sleeping position—Different positions have different support requirements, so the best King mattress will depend on whether you’re a side, back, stomach, or combination sleeper. The best mattresses for back and stomach sleepers are usually firmer, while conforming mattresses tend to be the best beds for side sleepers.
- Weight—Heavier sleepers not only tend to sleep hotter, but they experience more sinkage, meaning that a medium-firm mattress may feel soft to a heavyweight or tall individual. Similarly, lightweight or petite individuals who desire firm beds may find their match in mattresses that feel soft to most sleepers.
- Pressure Relief—You’ll want to look for a mattress that relieves pressure for your specific sleep style. Some products do a better job of preventing aches and pains in lightweight stomach sleepers, others excel at accommodating heavy side sleepers. If we award a mattress a perfect score of 5/5 in pressure relief, it usually means that it works for the majority of sleepers.
- Temperature—Do you sleep cool or hot? All-foam mattresses tend to sleep hotter, although recent advancements have improved airflow and made mattresses more breathable. If temperature regulation is important, consider a hybrid or innerspring King size mattress or an all-foam variety with dedicated cooling properties. Check out our best cooling mattresses article for more information.
- Material—The bulk of mattresses on the market are innerspring, foam, latex, or hybrid styles. Each material has its own benefits and drawbacks, and they vary in cost, durability, and more.
- Firmness—While there’s no standardized firmness scale across the industry, mattresses range from 1–10 in firmness, with one being extra soft and 10 being extra firm. Your weight and sleeping position have the biggest impact on the firmness that feels best to you and supports proper spinal alignment. Our mattress firmness guide is a great resource if you’d like to learn more.
- Thickness—Most mattresses measure 10″ in thickness, but luxury and thick options can measure 15″ or more.
- Budget—Mattresses vary dramatically in price based on the quality of materials used, the make, the manufacturer, and other costs, like delivery fees. Budget mattresses can cost just a couple hundred dollars, whereas luxury King size mattresses can cost $2,000 or more.
- Performance factors—Consideration of a King-size mattress’ performance will give you a well-rounded perspective on the product’s pros and cons. Take note of properties like durability (how long it will last), motion isolation, pressure relief, temperature, off-gassing, and edge support.
- Noise—If you sleep with a partner, a noisy mattress can be a real annoyance. Even the slightest movement can cause a creak or groan that makes it difficult to sleep peacefully. Memory foam tends to do a very good job of suppressing noise, though a hybrid mattress with enough comfort layers can also do a good job of staying quiet.
- Policies—Third-party retailer and mattress company policies—such as shipping, warranties, returns, and trial periods—can greatly impact customer satisfaction and experience, especially if you’ll be shopping for your King size mattress online. Make sure you’re comfortable with the level of protection for the investment you’re making and with the trial and return policies, just in case you’re not happy with your purchase. Also be aware that failing to use proper foundation, box spring, or bed frame can also void your warranty.
- Mattress weight—By nature of their size, King mattresses tend to be heavier and bulkier. You may need help setting up your mattress.
- Durability—Durability is key for King size mattresses, which often support the weight of two individuals night in and night out. Research and read reviews about the mattress’ longevity, looking for answers to questions like, “Does it sag over time?” and “How’s the edge support?”
King vs. Queen Mattresses
If you’re shopping for a King size mattress, you’ve probably also weighed the option of buying a Queen instead. Queen mattresses are more affordable, and if you’re a single person with an average body type, they likely provide enough space for you to be comfortable. That said, there are plenty of reasons why a King might be the right choice for you.
Most importantly, you’ll have more room on a King. A standard King mattress measures 76” x 80”, which is 16” wider than the queen’s 60” x 80” measurements. Whether it’s just you, you and a partner, or you and a pet, this extra 16″ will come in handy if you like to spread out, move around a lot, or even get some space between you and your partner.
A Queen does have it benefits, though. As I mentioned above, they are more affordable. They’re also lighter and therefore easier to move around, flip, or rotate. If you want your next mattress to be something that you spend many, many years on, then a King might be worth it for you. If this is more of a transition mattress, consider a Queen.
For a more comprehensive breakdown of the great King vs. Queen debate, take a look at our article on King vs. Queen size mattresses, or head over to our mattress size guide.

Mattress Size Guide
Types of King Size Mattresses
A bigger mattress can solve issues of disturbances like snoring, turning, tossing, and cover-stealing from a partner. If you’ve decided that a King bed is what you need, you’ll need to decide on the exact type of mattress you’re after. Here are the details and dimensions of the most common King size mattresses.
King
One size larger than a Queen, a traditionally sized King provides sleepers with an additional 16″ of width. A standard King measures 76″ x 80.”
Eastern King
An Eastern King is simply a synonym for a standard King, and it also measures 76″ x 80.”
California King
The only difference between a California King and a standard/Eastern King is in the width and length. California Kings measure 72″ x 84,” so they’re best for especially tall individuals and those who enjoy extra space.
Split King
A Split King, otherwise known as a Dual King mattress, comes in two pieces rather than one. Each piece is roughly the same size as a Twin mattress. Creating a King bed out of two separate mattresses allows each partner to customize their firmness level or position (with an adjustable base), while still sharing closeness with their partner.
Pros & Cons of King Mattresses
PROS
- More space
- Less tossing and turning
- Proper sleeping positions
- Kid- and dog-friendly
CONS

Who Is a King Mattress Best For?
Couples: Some couples snuggle up real close when they sleep; some couples like to preserve their personal space. Whether it’s because you or your partner easily overheat, or because one or both of you don’t like to be touched in your sleep, the extra foot of room that a King provides makes it a whole lot easier for couples to sleep exactly how they want to. Want more info on sleeping with a partner? Check out our couples sleep guide.
People with Pets and Kids: Having pets or children means that you may have to share your bed from time to time. Although they might be smaller than you, kids, cats, and dogs can take up a considerable amount of space, making your sleep situation less comfortable. A King size bed provides more surface area, meaning more room for everyone to relax.
Individuals Seeking More Space: Most individuals opt for a Queen mattress, as it provides substantial surface area for one person. If you’re one of those people who loves to spread out and not be anywhere near the edge of the bed, however, maybe a King size mattress would be more to your liking.
Those with Large Bedrooms: Room size becomes a major factor when shoppers realize that a King is more than a foot wider than a Queen. Leaving two feet of space on three sides of your room is recommended by interior designers, but that’s the minimum. If you want to include a wardrobe, nightstands, and other pieces, you’ll need more room. The opposite is also true. If you have a very large bedroom, then a Queen may not look proportional, and so a King would be more appropriate.
Long Haul Mattress Shoppers: Do you hope for your next mattress to be a part of your home for a long, long time? If even a small part of you thinks that you may want a King instead of a Queen several years down the road, then it may be in your best interest to purchase a King size mattress now.
Mattress Materials
If you’ve chosen to purchase a King size mattress, the final step before choosing a brand will be to determine which mattress materials best suit your sleep preferences and needs.
King Size Memory Foam Mattresses
Memory foam’s contouring ability is generally unmatched in the mattress world. The layers of foam react to your body and cradle all of the sensitive pressure points, like hips and shoulders. These foam layers also isolate motion really well, meaning late night movements won’t transfer to your partner’s side of your King size bed.
Who Are Memory Foam Mattresses Best For?
- Sleepers who enjoy deep contouring
- Couples
- Side Sleepers
If you want to learn more, head on over to our best memory foam mattresses guide.
King Size Innerspring Mattresses
Innerspring mattresses have two big things going for them: breathability and responsiveness. Constructed without thick layers of foam or latex, these beds have excellent air flow. Responsiveness refers to how easy a bed is to move around on, and if you’ve ever bounced around on a steel coil bed, then you know how springy they can be. If you tend to sleep hot or switch positions often, then an innerspring King mattress may be right for you.
Who Are Innerspring Mattresses Best For?
- Hot sleepers
- Budget shoppers
- Stomach sleepers
If these factors are important to you, check out our best innerspring mattress list.
King Size Latex Mattresses
Latex Kings offer comfort, support, and peace of mind. What do we mean by that? Well, many latex mattresses are manufactured with the environment in mind. The best way to tell whether or not a mattress brand uses sustainable processes and materials is to take a look at their certifications. The Global Organic Latex Standard (GOLS) and OEKO-TEX Standard 100 are good indicators of a product that is earth-friendly.
Who Are Latex Mattresses Best For?
- Eco-conscious shoppers
- People who enjoy a bouncy, responsive mattress
- Those looking for a durable product

King Size Hybrid Mattresses
At last, we arrive at hybrids. These mattresses are very interesting, because they combine elements from the three mattress types that we’ve already covered. Built with a support layer of springs and top layers of either memory or latex foam, the best hybrid mattresses offer the breathability and responsiveness of innerspring, along with the comfort and pressure relief of memory foam or latex.
Who Are Hybrid Mattresses Best For?
- Sleepers looking for the benefits of both foam and coils
- Luxury mattress shoppers
- Back sleepers

FAQ
What is the best affordable King size mattress?
The Cocoon Chill is a good King mattress for a reasonable price, but if you’d like more options check out our list of the best affordable mattresses.
How thick should a King size mattress be?
Most mattresses fall between 8 and 13 inches in thickness, and King beds are no exception. If you’re after something with good durability, you’ll want a mattress closer to 13 inches in thickness, though you’ll likely have to spend more money.
How often should I replace my mattress?
Generally, it’s recommended that you replace your mattress every seven years, but this number can change depending on the quality of the product and how well you take care of it. Some mattresses can maintain their quality for ten years or even longer. For more information, head over to our article, “How Often Should You Replace Your Mattress?”
Why is there a hump in the middle of my King size mattress?
That hump, also known as a king’s ridge, develops due to uneven weight distribution on your mattress. If you’re trying to fix it, we suggest you use a mattress topper. Not only will it help reduce the ridge, it will also add some comfort to your mattress.
If you’re trying to prevent the hump from forming, make sure that you regularly rotate your mattress, and try sleeping closer to the center of the bed.
Conclusion
If you’re on the hunt for a King-size mattress, you’re already well on your way to more comfort and better sleep. Most owners of King-size mattresses will tell you that the extra expense is worth it.
