Being king is good.

If you are going to go big or go home with a new mattress, you should make sure you get the best one.

We have rounded up some of the best king-size mattress options available. We have some shopping tips for you.

There are a few different types of king-size mattresses on the market.

  • Memory foam mattresses: This popular option is loved for its body-hugging ability. However, some people dislike the feeling of sinking into memory foam.
  • Latex mattresses: While similar to memory foam mattresses, latex mattresses are known for improved breathability and bounce-back factor. They can also be more durable and cooler than regular memory foam. Latex, of course, is not the pick for people with a latex allergy.
  • Innerspring mattresses: These are more traditional mattresses that use a steel coil support system. They’re long lasting and affordable, but they usually only have one thin layer of padding.
  • Hybrid mattresses: These offer the best of both worlds: a coil spring base topped with layers of latex or foam. This blend gives comfort, durability, and support. Plus, hybrid mattresses work well for many sleeping styles.

There are several sizes of king-size mattresses.

  • King is typically 76 inches wide by 80 inches long.
  • California king (typically 72 inches wide by 84 inches long, which is great for sleepers over 6 feet tall)
  • Each side is able to raise and lower.
  • Alaskan king (typically the largest mattress available, at approximately 108 inches wide by 108 inches long)

Crowning the best kings took a lot of work. Here is how we did it.

  • We reviewed company policies: Specifically, we dove into warranties, in-home trials, shipping, and return policies.
  • We looked at company reputation and transparency: Each brand we feature has a positive reputation, transparent business practices, good customer reviews, and meets federal flammability requirements.
  • We prioritized: We chose mattresses with good materials certifications and included brands that sell a range of king sizes.

There are plenty of people who can fit on a king-size mattress.

  • tall people or people with more weight who want comfortable weight distribution and space to sprawl out
  • restless sleepers who need more room for tossing and turning
  • People who want to have more space for their furry friends.
  • sleeping partners who want a little more room, less motion transfer, or space for activities

Pros

  • Roomy: King-size mattresses provide plenty of space for partners to get comfy, roll over, and stretch out — not to mention, extra space for kiddos and pets to join.
  • Comfier for sleepers with more weight: These mattresses are usually supportive, long, and wide, accommodating people of all body types and sizes.
  • Options: You can find memory foam, latex, innerspring, and hybrid king-size mattresses. There are also extended king sizes available, including California king, split king, and Alaskan king.

Cons

  • Higher price point: King-size mattresses, bedding, and other accessories are often pricier than the more common queen-size mattresses.
  • Takes up more space: King-size mattresses take up more space in the bedroom. A larger mattress may also take more effort to move.
  • May feel too big for some sleepers: Petite sleepers may feel like the bed has more space than needed.

When shopping for a king-size mattress, do your research and consider your needs, lifestyle, and sleeping style (side, back, stomach, etc.). Many mattresses will say what sleeping position they’re intended for, but in general, opt for something firmer if you’re a back or stomach sleeper, and something softer if you’re a side sleeper.

“Take a look at the mattress’s materials. You may want to look at those who have certifications. Think about whether you prefer foam or springs.”

“If you can, you can try out the mattresses. A test drive is the best way to find out if a mattress is right for you. If you can’t try a mattress out before you buy, you can buy from a company that offers an in- home trial period and a good return policy. The warranty can be looked at to see what is covered.”

Is a king-size mattress the biggest mattress?

Nope. There’s a range of king-size mattresses available beyond just a standard king. Alaskan king is usually the largest king-size mattress available, measuring approximately 108 inches wide by 108 inches long.

What’s the difference between a king-size mattress and a California king?

A standard king-size mattress is usually 76 inches wide by 80 inches long, while a California king is typically 72 inches wide by 84 inches long. Thanks to its extra length, a California king tends to be the best choice for sleepers over 6 feet tall.

What’s a split king mattress?

Think of this bed as two twin XL mattresses pushed together. This type of king-size mattress is usually designed to work with an adjustable base and to cater to each sleeper’s needs. One sleeper can sit up, while the other rests in a horizontal position.

“Each sleeping person has their own mattress, which is good for reducing motion transfer. You won’t be able to feel your partner moving. The mattresses tend to cost more and require more sheets.”

How can you choose which king-size mattress to buy?

The mattress should be accommodating to who it is. A tall person? A person with more weight? Multiple children and pets? Then, take a look at how much space you have. Can you move the mattress through the halls and doorways to get to the bed frame?

If you know the answers to the questions, you can check out the range of king-size mattresses available to find the best dimensions for you and your space.

There are many king-size mattress options.

These 13 options checked our boxes for reputation and quality but be sure to do your research before committing to a brand. Try to buy from a company that offers an in- home trial, or try to test the mattress out in person.
