The Best King Size Mattresses

You deserve the best of the best.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Once you've tried a King-size mattress, it's hard to go back to anything else. Especially if you share the bed: A King is equivalent to two Twin XLs, giving both sleepers ample space. But comfort doesn't come cheap; King-size mattresses are often 20% to 30% more expensive than the same Queen-size model, so you'll want to make sure you're investing in something worth the added cost.

At the Good Housekeeping Institute Textiles Lab, our scientists have vetted hundreds of popular mattresses and analyzed survey feedback from 10,000 mattress owners. In the past few years, we've tested 201 mattresses (and counting) with hundreds of at-home consumer testers to find the best mattresses available.

Best Overall

Saatva Classic Mattress

Classic Mattress
Credit: Good Housekeeping / Mike Garten

Pros

  • High scores for comfort and support from long-term users
  • Excellent customer service with free delivery, setup and old mattress removal
  • Good edge support and breathability

Cons

  • Runs firm, according to testers

EXCLUSIVE DISCOUNT: Good Housekeeping readers can take 20% off their Saatva mattress orders (with a minimum $1,000 spend) when using our exclusive link through Memorial Day.

Mattress type: Innerspring | Height: 11.5 or 14.5 in. | Firmness: Plush Soft, Luxury Firm, Firm | Trial period: 365 days (with a $99 return pickup fee)

Who it's best for: Users looking for breathability and support above all else or those looking for full-service delivery.

Saatva's Classic Mattress consistently performs well in our tests due to its excellent support. It's best suited for those who prefer a traditional mattress over the sink-in feel of memory foam and comes with free full-service setup and mattress removal. The sleep trial is generous at 365 days, though you'll need to pay a $99 pickup fee for returns.

How it performed in our tests:

✔️ Breathable design: We like how Saatva uses two layers of coils for optimal ventilation. Out of over 100 Saatva owners on our tester panel — hot sleepers included — none had any complaints about overheating. Several even told us it was an improvement over the other foam and innerspring beds they've owned.

✔️ Top-notch support: Our testers consistently highlighted the Saatva Classic's supportive feel. Long-term users gave it high marks for its comfort and support, and several swore that it helped ease their chronic back pain. Others praised the edge support, which they said made it easier to get in and out of bed. The caveat is that the mattress tends to run a bit firm as a result, so it's unideal for those who want a plush bed.

✔️ Excellent customer service: Panelists were impressed with the brand's helpful customer service. Some told us that when they called the support hotline, they received near-instant attention compared to the all-too-common long wait times many expect.

Allswell Luxe Hybrid

Luxe Hybrid
Now 22% Off
Credit: Good Housekeeping / Mike Garten

Pros

  • Low cost for a hybrid with foam and coils
  • Fast delivery and easy DIY setup
  • Users said it feels like an expensive hotel bed

Cons

  • Lacks edge support

Mattress type: Memory foam | Height: 10 in. | Firmness: Medium | Trial period: 90 days

Who it's best for: Budget-conscious shoppers looking for solid comfort at a good value. In our tests, this bed was favored by younger adults in their 20s.

If you've got a limited budget, the Allswell Luxe Hybrid is a great option. It's a simple hybrid with cushy foam that contours to your body without sinking in under your weight. While there's no perfect mattress for everyone, this one has outperformed many mattresses in our tests, including some that were three times the price.

How it performed in our tests:

✔️ Plush comfort: Allswell calls the mattress medium, but we've found that it has a medium-soft feel. It was well-liked in our tests for its pillow-y texture: The combination of pressure-relieving foam and coils provided a balanced feel. One user told us, "This mattress is supportive and plush, and it feels like a fancy hotel bed." Another tester shared, "I like the support that it provides without being firm."

✔️ Excellent value: The average cost of a Queen-size hybrid mattress in 2023 was $2,050, so at this price point, it's already a steal. On top of that, our testers couldn't believe how expensive it it felt. They also appreciated how it came boxed for setup at their leisure. In recent years, we've seen mattress prices increase regularly, but this one has stayed consistent over time.

✔️ Edge support: The caveat with this one is that our testers found the edge support lackluster. This means it can sink in under your weight when you get in and out of bed, which can be an issue for those with mobility limitations.

Best Memory Foam

Pros

  • Adapts precisely to your body shape
  • High-quality Tempur-Pedic foam at a lower cost
  • Excellent motion isolation, according to testers

Cons

  • 10-inch height is on the lower side

Mattress type: Memory foam | Height: 10 in. | Firmness: Medium | Trial period: 90 days

Who it's best for: Side sleepers in search of precise pressure relief, couples who need motion isolation and anyone who wants Tempur-Pedic's memory foam at a more affordable price point.

There’s nothing quite like a Tempur-Pedic mattress: The foam is designed to precisely adapt to your body and offer personalized support and pressure relief. We like that this model ships straight to your door, so it comes at a lower price point than the brand's premium models, but it stands a bit lower at a 10-inch profile.

How it performed in our tests:

✔️ Pressure relief: The foam molds to your body, cradling key areas like the hips. This helps the bed promote neutral spinal alignment while cradling your hips and shoulders, which is essential for sleeping on your side. Testers loved the feel: One compared it to "sinking into a warm hug when you sleep."

✔️ Precise support: The brand notes that the bed may feel firm when you first lie down, but our testers confirmed that it quickly molds to properly contour your body for personalized support. One tester commented, "I feel like my entire body is supported in a very gentle way."

✔️ Motion isolation: When it comes to motion isolation, Tempur-Pedic does it best. One tester shared, "When my husband gets into bed (always after I go to bed), I feel nothing. I am not disturbed at all and almost never even wake up if I am asleep."

Best Hybrid

Bear Elite Hybrid

Elite Hybrid
Now 35% Off
Credit: good housekeeping / mike garten

Pros

  • Ergonomic design
  • Perfect comfort and support ratings from every tester
  • Users reported improved sleep quality

Cons

  • Outer cover pilled over time

EXCLUSIVE DISCOUNT: Good Housekeeping readers can take 40% off their Bear mattress orders with code GH40 through Memorial Day.

Mattress type: Hybrid | Height: 14 in. | Firmness: Soft, Medium, Firm | Trial period: 120 days

Who it's best for: Those who can't choose between memory foam and innerspring, or people with back pain.

If I had to recommend just one hybrid mattress, it would be the Bear Elite Hybrid. It’s great for those who are accustomed to the traditional feel of an innerspring mattress but want to try memory foam. Few mattresses we’ve tested offer this level of comfort and support — Bear was one of the first brands to use a zoned layout, providing extra give in key areas to help maintain proper spinal alignment.

How it performed in our tests:

✔️ Comfort & sleep quality: It earned perfect comfort and sleep quality ratings from all of our consumer testers. Several shared that their sleep quality has noticeably improved: They have better, more uninterrupted sleep than on any other mattress they tried before. One tester commented, "I find myself genuinely looking forward to laying down at the end of the day — and not just because I'm tired, the mattress is that comfortable."

✔️ Support: While the foam on top provides comfort, the mattress doesn't compromise on support. We were also impressed with the reinforced edges, which proved fairly supportive, especially for a boxed mattress.

✔️ Durability: While it's a newer model (first launched in 2022), it has held up well in our tests so far, aside from some pilling on the outer cover after the two-year point.

Note: Bear claims to use natural minerals that promote recovery in its materials. We couldn’t verify these claims in our research but still stand by its comfort.

Best for Couples

Helix Dusk Luxe

Dusk Luxe
Now 20% Off
Credit: good housekeeping / mike garten

Pros

  • Good compromise for partners with different preferences
  • Cushy and responsive foam
  • Helpful side handles

Cons

  • Motion isolation could be better

EXCLUSIVE DISCOUNT: Good Housekeeping readers can take 27% off their Helix mattress orders with code GH27 through Memorial Day

Mattress type: Hybrid | Height: 13.5 in. | Firmness: Medium | Trial period: 100 days

Who it's best for: Couples, especially those with different sleep styles, or combination sleepers who change positions throughout the night.

If you and your partner have different sleep positions or firmness preferences, mattress shopping can be tough. The Helix Dusk Luxe lets you meet in the middle — quite literally — it has a true medium feel that works wonders for couples with seemingly incompatible preferences.

How it performed in our tests:

✔️ Responsive feel: Unlike other hybrids, this mattress uses a blend of latex and memory foam, so you feel like you're sleeping on top of the bed but still have the pressure relief from foam. This makes it easier for combination sleepers to change positions throughout the night. The caveat is that latex isn't as motion-isolating as foam, but several couples said the comfort was worth the trade-off.

✔️ Crowd-pleasing comfort: One tester highlighted the soft yet supportive pillow top and said, "Its cushiony feel has me thinking I'm sleeping on a luxury hotel mattress." Others shared that they feel comfortable in any sleep position on this bed.

✔️ Luxurious height: Standing at a whooping 13.5 inches, this bed feels luxurious, especially with the cooling pillow-top add-on, and it's especially tall for a boxed mattress. While many liked the generous height, some noted that it made for a heavy mattress. We like that Helix has since added handles to help with maneuvering.

Best for Back Pain

Nolah Original Mattress

Now 35% Off
Credit: good housekeeping / mike garten

Pros

  • Testers swore it eased back pain
  • High scores for comfort and support
  • Users said it sleeps cooler than other foam models

Cons

  • Low height may be unideal for those with mobility issues

Mattress type: Memory foam | Height: 10 in. | Firmness: Medium | Trial period: 120 days

Who it's best for: Users with chronic joint pain who need a pressure-relieving bed that won't compromise on long-term support.

If you suffer from pain in your shoulders, hips or lower back, maintaining a neutral spinal alignment while sleeping is key. Our top-tested recommendation is Nolah's Original Mattress, which comes backed by dozens of positive reviews from our testers and panelists, who swore it made all the difference for their chronic back and hip pain.

How it performed in our tests:

✔️ Pressure-relieving and responsive foam: With a balanced feel, the foam contours well to your body without sinking in too much. Many testers who've suffered from back, hip and shoulder pain told us this bed notably eased their discomfort. One praised the model for its comfort, and shared that it "offers support while still cradling pressure points." Another user told us, "[this mattress was] significantly helpful in relieving back pain for my husband who has scoliosis."

✔️ Versatile design: The medium firmness works well for a range of users, who gave it top scores for comfort, support and sleep quality. Our testers also appreciated the motion-isolating foam.

✔️ Temperature control: While memory foam is notorious for overheating, panelists told us that this one sleeps surprisingly cool compared to others they've owned.

✔️ Height: Our reviewers were surprised by how comfortable this slim mattress felt, and one liked how well it slotted into her sleigh-style bed. The caveat is that the 10-inch height may be too low for those with mobility issues, depending on the height of your bed frame.

Best Cooling

Purple Mattress

Mattress
Credit: good housekeeping / mike garten

Pros

  • Breathable grid layer on top
  • Users said it feels like a perfect balance of soft and firm
  • Good motion isolation in tests

Cons

  • Hard to maneuver despite low-profile height

Mattress type: Foam with polymer grid | Height: 9.25 in. | Firmness: Medium Firm | Trial period: 100 days

Who it’s best for: Hot sleepers who need optimal ventilation and anyone looking for something new. It's also great for couples in search of a responsive bed that still has good motion isolation.

When you sleep hot, it's crucial to find a mattress that's breathable and cooling. We like that Purple uses a one-of-a-kind, grid-shaped elastic top layer that proved airy and supportive in our evaluations. Our testers also highlighted its responsive yet pressure-relieving feel.

How it performed in our tests:

✔️ Temperature control: Testers and panelists agreed that it felt noticeably cooler than other beds they've slept on. Several hot sleepers even called it "too cool" in the winter.

✔️ Standout feel: The top GelFlex Grid layer has a unique texture: It feels cradling (like memory foam) but won't sink in under your weight. One user said, "It's 'springy' and conforms to my body while still being supportive." Others praised the balance of soft pressure relief with firm support.

✔️ Good motion isolation: Responsive mattresses have a nice bounce but typically fall flat when it comes to motion isolation. However, our testers found that they couldn't feel their partners tossing and turning as much on this one.

✔️ DIY setup: This mattress comes rolled up and ships straight to your doorstep. Most users reported no issues with DIY setup, but some found that the grid layer made the mattress difficult to maneuver.

Best Firm Foam

Tuft & Needle Original Mattress

On Sale
Original Mattress
Now 19% Off
Credit: good housekeeping / mike garten

Pros

  • Supportive foam with great motion isolation
  • Quick shipping with DIY setup
  • Affordable compared to similar brands

Cons

  • Lacks edge support

Mattress type: Memory foam | Height: 9.5 in. | Firmness: Firm | Trial period: 100 days

Who it’s best for: Users who want pressure relief with a firmer feel rather than cushy foam. It's designed for all sleep positions but performed best amongst back and stomach sleepers in our tests.

For those who like the idea of memory foam but prefer a firmer bed, this model offers just that. It consistently receives good feedback for its reliable support and no-frills design. Others also highlighted its fast shipping and affordable price point.

How it performed in our tests:

✔️ Fast delivery & easy setup: None of our testers reported any issues when it came to setup, and our panelists appreciated how quickly it arrived after ordering.

✔️ Supportive foam: Compared to other memory foam mattresses, Tuft & Needle's foam has a responsive feel. It contours nicely to your body but won't sink in under your weight. One user shared, "I like that I don't sink in," while another told us, "The mattress feels firm and supportive." Plus, many liked that the foam still offered good motion isolation, so their partners couldn't feel them move around in bed.

✔️ Pain relief: Testers frequently reported that it helped alleviate chronic back pain. A recent tester noted, "my back felt better on this mattress," while a user who had it for five years said, "my mattress is so much more comfortable than any mattress I've ever had in the past. My husband and I both experience much less back pain."

✔️ Edge support: The main complaint we've received from users is that there isn't as much edge support, meaning it may sag when you sit on the side of the mattress, but this is typical for memory foam.

Best Soft

Puffy Lux Mattress

Lux Mattress
Now 46% Off
Credit: Good housekeeping / mike garten

Pros

  • Plush with contouring support
  • Testers said it improved their sleep quality
  • Kept its shape well in at-home tests

Cons

  • Testers didn't seem to notice claimed cooling effects

Mattress type: Hybrid | Height: 12 in. | Firmness: Medium Plush | Trial period: 101 days

Who it's best for: Side sleepers, those with back pain or anyone seeking a plush, cushy bed that doesn’t sink in too much

This mattress feels indulgent and plush without skimping out on support, which was the number-one concern from our panelists who prefer a softer feel. In our tests, it cushioned pressure points without sinking in or sagging under pressure and earned top scores amongst side sleepers.

How it performed in our tests:

✔️ Cloud-like comfort and support: Testers praised the "cradling" feel and highlighted how the bed gently molded to their bodies without collapsing in under their weight. One described it as "dreamy," while another shared, "It’s so soft, it feels like sleeping on a cloud." Others liked how they still felt supported by the coils.

✔️ Pain relief: Our reviewers agreed that they experienced fewer aches and pains on this bed (especially when compared to innerspring beds). One tester even shared, "My favorite thing about this mattress is that it completely relieved my lower back pain!"

✔️ Shape retention: Although it conformed to users' bodies, it still held up to pressure. Users reported that it kept its shape nicely without forming indents.

✔️ Temperature control: Our testers were mixed when it came to how cool or warm they slept. Despite the cooling features throughout the mattress, none noticed a significant cooling effect.

Best Firm

Stearns & Foster Estate Mattress

Estate Mattress
Now 7% Off
Credit: Good Housekeeping / Mike Garten

Pros

  • Unique innerspring coils for firm support
  • High-quality and hand-crafted materials
  • Available to try in stores

Cons

  • Expensive

Mattress type: Innerspring | Height: 14.5 in. (or 15 in. with a pillow top) | Firmness: Soft, Firm, Pillow Top Soft, Pillow Top Firm | Trial period: 90 days

Who it's best for: Stomach sleepers, those with heavier body weights or anyone who likes a firm mattress with a luxurious innerspring design.

Stearns & Foster is one of the best when it comes to firm beds, and the Estate is the brand's best-selling model. The firm is labeled as a 9 out of 10 on the firmness scale and won over our testers who swear by a firm, supportive bed. It also uses a unique, complex coil system with high-density memory foam from its sister company Tempur-Pedic.

How it performed in our tests:

✔️ Excellent support: When reviewing surveys from 150 Stearns & Foster mattress owners, support stood out above all else. One tester called his first month on the mattress a "revelation" and commented, "I love how firm and structured the mattress felt. I've been sleeping much more soundly."

✔️ Sleep quality: While this brand has a higher price point than our other picks, our panelists told us it was worth the splurge. Users told us that their sleep quality noticeably improved from the very first night.

✔️ Convenience: If you prefer to try before you buy, the brand is available in stores across the country. Otherwise, it comes with free delivery and in-home setup. Keep in mind that each bed is made-to-order, so it'll take a while to arrive.

Other mattresses we tested

double line break

We've tested over 200 mattresses. Here are our thoughts on some of our other favorites alongside popular models and why they didn't make the cut.

Serta's Perfect Sleeper Hybrid is a popular choice amongst our panelists for its no-frills comfort and price point (under $1,000 for a Queen and under $1,500 for a King). It's received good feedback from many users, but they're divided on longevity, with some noting that it didn't hold up as well as they wanted over the years.

The Avocado Green Mattress is our pick for the best organic mattress. It's the quintessential latex hybrid, so it's great for someone who wants the ultimate responsive bed. Latex hybrids usually don't perform as well as foam hybrids in our tests as testers prefer a cushy feel over a springy top, so we've omitted it from our list.

Sleep Number's p6 Smart Bed is good for couples who disagree on firmness but comes at a steep price tag. It's our favorite smart bed, as no other adjustable mattress has the level of precise firmness control, but it's a bit more specialized.

DLX Premier Hybrid: We're currently in the process of testing this popular hybrid. So far, we like its customizability: You can choose different firmness levels for each half of the bed at no extra cost.

DreamCloud Hybrid Mattress: We've had mixed reviews for this brand. While many found this model (the brand's original mattress) initially comfortable and dreamy, they noticed sagging earlier than expected. Testers also agreed that it ran a bit too warm.

Brooklyn Bedding Aurora Luxe: This is another popular cooling mattress. It's not as cooling as ones from Purple, but it's less expensive and it's a solid option for those who like the plush texture of memory foam. Note that it runs slightly soft.

Leesa Sapira Hybrid / Leesa Original Hybrid: In our surveys, Leesa's hybrid mattresses received mixed reviews for long-term durability. Some swore by the brand for its soft, cushy foam, but others have reported issues with repeated sagging. I find that the Original Hybrid has a balanced, uniform feel, making it more versatile, while the Sapira Hybrid is best suited to those who love plush memory foam.

The Winkbed: This is another popular hybrid mattress, but it's received mixed reviews in our surveys and tests. Our most recent tester found the support solid and uniform but noted that it slept notably hot and ran firm, ultimately aggravating her shoulder and lower back over time.

How we test mattresses

double line break

To find the best mattresses on the market, our team of expert scientists and engineers have:

✔️ Researched hundreds of new models each year, diving deep into the details around materials, design, brand reputation, customer service and online reviews.

✔️ Surveyed more than 10,000 readers on our GH survey panel, analyzing over 170,000 answers to questions about the mattresses they own.

✔️ Sent over 200 mattresses to hundreds of consumer testers to review at home, both short and long term, in the past few years.

✔️ Reviewed materials, claims and third-party certifications to ensure the materials and manufacturing process are truly organic and not just promoting greenwashing claims.

✔️ Leveraged our backgrounds in fiber science, materials engineering and consumer science to assess everything from materials and structure to brand reputation.

✔️ Interviewed dozens of medical professionals and kept up with relevant sleep studies.

✔️ Visited dozens of mattress factories and showrooms, interviewing everyone from CEOs to in-house product experts.

What we consider

Here are the key aspects we look at when reviewing user feedback:

✔️ Ordering and delivery: Users provide ratings and comments about the ease of ordering, how quickly it arrived and whether there were any issues throughout these steps.

✔️ Setup: Whether it's DIY or white-glove delivery, we explore how easy the process was and whether the mattress took shape quickly.

✔️ Firmness level: Often, the perceived firmness doesn't match the brand's specified level. This helps us understand how soft or firm it feels in real life.

✔️ Comfort and support: Testers weigh in on whether they liked sleeping on the mattress immediately and again later in the review period. They can provide comfort and support ratings as well as detailed comments.

✔️ Temperature: We ask users whether they stayed at a comfortable body temperature throughout the night so we can note whether any cooling features were observed.

✔️ Edge support: Reviewers let us know whether the bed sinks when they sit on the edges or if it holds the shape well under weight.

✔️ Sleep quality: Respondents report if the mattress has had any effect on their sleep, whether they woke up sore and whether they are overall satisfied with the mattress. They also have the opportunity to compare the mattress with other models they've owned.

✔️ Additional feedback: Through a series of open-ended questions, testers can share any likes, dislikes and further comments about their experiences.

What to keep in mind when shopping for mattresses

double line break

Here are some important things to keep in mind when shopping for your next mattress:

✔️ Sleep position: The goal is to keep your spine in neutral alignment, so factoring in how you sleep can help narrow down your search.

  • Stomach sleepers should choose a firmer mattress.
  • Side sleepers need a softer mattress to limit additional stress on the pressure points like the shoulders, hips and knees.
  • Back sleepers and those who change positions fall somewhere in between, making a medium firmness level ideal.

✔️ Body type: Heavy people often need a firmer bed for support, while lightweight frames are better served by softer mattresses. Take into account both your weight and preferred sleep position when choosing the right firmness level for your next mattress purchase.

✔️ Temperature: Hot sleepers or anyone dealing with night sweats would benefit from a mattress with cooling properties. Memory foam tends to sleep hot, so look for a mattress with coils for airflow or cooling technology like copper particles, gel or phase change technology that's added to the foam.

✔️ Back pain: If you suffer from back pain, look for a pressure-relieving mattress with a medium firmness level for a balance of cushioning and support.

✔️ Trial period: It's difficult to know whether a mattress is a good fit for you without sleeping on it. Luckily, most mattress companies offer an any-reason return period of at least 100 nights as part of a sleep-trial guarantee. So before you buy, check whether there are any hidden return fees and the steps for returning to avoid any surprises.

✔️ Certifications: It's important to know the difference between the various emblems you see when you shop since they often get mistaken for meaning the mattress is natural or organic. Here's a breakdown of the most common certifications:

  • CertiPUR-US: This certifies whether any foam in the mattress is made without certain harmful chemicals and has been tested for low VOC emissions.
  • OEKO-TEX: The Standard 100 by Oeko-TEX shows whether any fabric (like the outer cover) has been tested to ensure there are no unsafe levels of known harmful chemicals.
  • GOTS: The Global Organic Textile Standard shows that the mattress follows strict standards throughout the entire production process. This is the gold standard when it comes to picking out an organic mattress made of natural materials. Just be aware that this certification is commonly misused by brands who use just one organic component (e.g., an organic cotton outer cover), so you can always check the GOTS public database to be sure.
  • GOLS: The Global Organic Latex Standard is similar to GOTS, but it shows that any latex is certified organic. You'll often see these two organic certifications used together.

How much should I pay for a good King-size mattress?

double line break

In our tests, we've found that a good mattress typically costs between $1,200 to $2,500 for a King size. That being said, you can still find great, affordable mattresses well under $1,000, and there are also luxury mattresses that prove worth the splurge.

Still, we've seen mattress prices steadily increase in recent years, and we expect them to continue rising.

What's the difference between King, California King and Split King?

double line break

A King-size mattress is 76" x 80". In comparison, a California King is less wide but longer at 72" x 84", making it great for taller individuals. A Split King mattress is the same size as a King but instead of one mattress, it's comprised of two Twin-XL-size mattresses, which fit in a King-size bed frame.

The Split King size is most popular for using on a Split King adjustable base but also good for couples with different firmness preferences or those who want true motion isolation.
