About Our California King Mattresses

Want a little extra space when you sleep? A California king mattress could be just what you’re looking for. The California king is 4 inches longer than a standard king mattress, giving you more room to stretch out and sleep comfortably, which is ideal for tall sleepers or couples who want a little extra space. 

At Sit 'n Sleep, we offer a wide selection of California king mattresses from top brands such as Beautyrest, Purple, and Hybrid Infinity, so you can find the right one for your needs and budget. Shop our superior selection today!

What Is a California King?

California king, Western king, Cal king…no matter what you call it, this is one luxurious mattress.California king beds have been a popular choice since they came on the scene in the mid-20th century. That’s because a California king size bed is incredibly spacious at an average of 72” wide and 84” long. The generous sizing makes this bed a perfect fit for large bedrooms. Need help deciding if a Cal king mattress is right for you? Our expert sleep consultants can help you choose the right mattress that aligns with your sleep position, body type, and lifestyle.

What Are the Benefits of a California King Mattress?

Choosing a mattress is an important decision, setting the foundation for a relaxing sleep space. If you’ve selected a Cal king bed, you’ll get a mattress that offers:

Extra space: California king beds and mattresses give you more room than a standard king size, making them a great option for tall sleepers or couples, or even families whose kids or pets like to snuggle with their parents.

Comfort: A California king mattress provides plenty of space to spread out. It’s also good for “active” sleepers who tend to move around a lot in the middle of the night.

Easy to care for: A Cal king mattress is easy to turn and rotate, which helps preserve the quality of your mattress and extend its lifespan.

How to Choose a Mattress for Your California King Bed

When you’re shopping for a California king mattress, here are a few things to keep in mind:

Firmness: It's important to choose a mattress that offers you the right amount of comfort and support. If you're a side sleeper, the mattress for your California king size bed should be soft enough to relieve pressure on your shoulders and hips. Back sleepers, however, may prefer a firmer mattress that provides extra support for the spine.

Construction: Today’s mattress shoppers have a variety of choices, including memory foam, innerspring coils, and hybrids, which are a combination of foam and coils. Memory foam mattresses conform to your body's contours for a customized sleep space. Innerspring mattresses offer more bounce and support. And hybrid mattresses give you the best of both.

Price: Mattresses for California king beds range in price from a few hundred dollars to several thousand dollars. The price will depend on the materials used, the brand, and other features.

Warranty: Most mattresses come with a warranty, so you’ll want to know the terms and conditions before you buy.

Why Buy a California King Mattress?

California Kings are legendary for being the biggest mattress on the market, but just knowing the size doesn’t really explain the appeal. There are lots of smart reasons to make something like a California King pillow top mattress your next choice, and it probably offers more advantages than you realize. Consider a few of the reasons people get excited about sleeping on one of these beds:

  • Never Run Out of Room - When was the last time you wanted less room in your mattress? With a California King you always have space to spare. If you get another pet, have another kid, or need more mattress for any reason, you won’t feel cramped in a California King. It’s a great option for your household’s sleep needs now and later.
  • Support Any Sleep Style - Some people like to sleep splayed out, while others want to surround themselves with pillows. No matter how you like to sleep, you want to have all the space you need. Due to the extra-large nature of a California King pillow top mattress, for example, you won’t ever feel like your mattress is cramping your sleep style. More room means more freedom to sleep as you like.
  • Don’t Disturb Your Partner - Just because you share a bed with your partner doesn’t mean you share the same sleep schedule. Perhaps you go to bed or get up at different times, or one partner is a light sleeper while the other tosses and turns. Since there is so much space to stretch out in a California King, partners have enough room between them to avoid disturbing each other.
  • Upgrade Your Bedroom - Your mattress is for sleeping, but lots of people lounge in bed as well. A California gives you enough space to lounge however you like - surrounded by books, gadgets, snacks, or company. Simply stated, if you’re going to hang our in your bedroom, wouldn’t you prefer to be in a big bed? Plus, since the bed is the centerpiece of the bedroom, the impressive size of the California King makes the space feel more accomodating and upscale.
