We compiled our list of the best California king mattresses based on the following:

  • Materials: We looked for and included California king mattresses with high quality foam and hybrid materials.
  • Sleep preferences and habits: Everyone sleeps differently, so we looked for mattresses that would accommodate different sleeping positions, preferences, and habits.
  • Company policies: The best way to test a mattress is to sleep on it, so we chose mattresses with generous trial periods and free or reasonable returns. Also, every mattress on our list is backed with a clear warranty you can easily find on its website.
  • Company reputation and transparency: With so many mattress brands out there, we took extra care to only recommend brands with good reputations and transparent business practices. Our vetting process includes a deep dive that considers everything from whether a company follows or leads industry best practices to whether a company is making unsupported medical claims.
  • Customer reviews: We carefully reviewed customer reviews and feedback to make sure we recommended the most loved mattresses on the market.

A California king mattress measures 72 by 84 inches. It’s identical to two twin XL mattresses put together.

Most people think California king mattress are bigger than standard King mattresses, but the real difference is the proportion of length to width. California kings are longer and narrower than standard king mattresses, which measure 76 by 80 inches.

California kings are typically a better choice for tall people who measure more than 6 feet, or bedrooms that are narrower.

To help you get started, we found 10 of the best California king mattresses.

Once you’ve decided that a California king suits your needs, there are a few other considerations.

While there’s no single best mattress for everyone, it’s important to choose one that suits your individual body type and sleeping preferences. Consider:

  • Mattress type: California king mattresses can be found in foam, innerspring, and hybrid options. Personal preference will play a big role in what feels best to you. If you’re unsure what you like best, a hybrid can be a good place to start, because it has elements from foam and innerspring mattresses.
  • Mattress performance: It’s also important to consider how mattresses perform when it comes to firmness, motion isolation, temperature regulation, edge support, and off-gassing (new mattress smell). Think about what matters most to you, and look for mattresses with positive reviews for those attributes.
  • Mattress materials: Pay attention to the materials used in a mattress. Look for high quality material certifications, like CertiPUR-US, Global Organic Textile Standard (GOTS), or Global Organic Latex Standard (GOLS). The better the materials used, the more durable your mattress will be and the longer it will last.
  • Trial period and warranty: It can be challenging to find the right mattress based on online descriptions alone — and lying on a bed for half an hour in a store isn’t necessarily a good indication of how it will perform over time either. Your best bet is to find a mattress that offers an in-home trial period of at least 30 days. It’s also a good idea to check the fine print, so you understand the process for returns or exchanges.

Who should buy a California king mattress?

Because it’s 4 inches longer than a standard king, a California king mattress is a good choice if you’re tall. Those extra inches give you room to stretch out without your feet hanging off the bed.

California king mattresses are also convenient if you have pets who sleep near the foot of the bed. Plus, the narrower footprint may be a better fit in some bedroom layouts.

Both the California and standard king mattresses are big beds, but the narrower width of the California king can be a good option if you like to sleep closer to your partner.

Keep in mind that both the mattress itself and accessories, like sheet sets, tend to cost more.

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

California king mattresses shouldn’t be confused with standard king mattresses.

At 72 inches wide and 84 inches long, a California king measures 4 more inches from top to bottom and 4 inches less from side to side.

Because the California king is both longer and narrower than a standard king, you’ll need a new frame and bedding if you’re planning to switch.

What’s a split California king?

The split California king mattress is exactly as it sounds: It’s essentially two separate mattresses that equal the same dimensions as a single California king.

The split California king can be a good option if you share your bed with a partner and have different firmness or temperature preferences, or if one of you is a restless sleeper.

If you upgrade to an adjustable base, you can further personalize your sleep experience without disturbing your partner. However, if you tend to roll toward the middle of the bed, you may find the split California king uncomfortable.

A California king mattress can be a great choice if sleeping space is an issue. While you’ll spend more for the mattress itself, you may find a California king to suit just about any sleeping position, habit, or preference.
