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 legroom. 

California king, Western king, Cal king…no matter what you call it, this is one luxurious mattress. California king mattresses 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.

At Sit 'n Sleep, we offer the best California king mattress selection 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’s the Difference Between a King and a California King Mattress?

As you can guess, a California king is bigger than a regular king mattress, specifically in length. At 84 inches long, the Cal king mattress is 4 inches longer than a king. It’s worth noting, however, that the Cal king’s width is 4 inches shorter than the king. So this is a bed that is great for people who are tall, but if you want a wide sleeping space, you might consider a king bed.

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 benefits including:

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.

Better sleep quality: In a smaller bed, you may feel cramped and your movements are inhibited (or you may bump into your partner while you sleep). Because of that, you may wake up each morning with stiff or achy joints from your uncomfortable sleep position. A California king gives you greater freedom of movement, so you can be well-rested every day.

Reduced back pain: That extra space in a California king mattress accommodates your sleep position so you can stretch out for full postural support and spinal alignment that alleviates pressure on your back.

Improved blood circulation: Another benefit of being able to move freely is that your blood can travel freely throughout your circulatory system, too.

Less disruption for your partner: It’s tough on your sleep (and your relationship!) if your partner constantly wakes you up by bumping into you in the middle of the night when they roll over or move around. With California king mattresses, there’s room for you both, which is especially helpful if one of you is an active sleeper or you both have different sleep schedules.

Accommodation for all body types: Because of its unique dimensions, this mattress is a good choice for people who are taller than average or who may need more room to sleep without having to curl up to fit in the bed. 

Potential mental health support: When you get high-quality sleep on a regular basis, it may boost your mood and support sharper cognitive function, and a larger bed can be conducive to that kind of rest.

Limited tossing and turning: With so much space in a California king, you don’t have to move this way and that throughout the night to get comfortable. Your body can relax with all that room to spare.

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.
Health and Lifestyle: You may choose a California king mattress because you need a mattress that will support healthy sleep habits, with enough room for you (and a partner) to maintain proper spinal support for pressure point relief. It also could be the best fit for your lifestyle; for instance, you may get visits in the night from pets or young children who want to snuggle, and a California king can fit everyone.

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 king gives you enough space to lounge however you like - surrounded by books, gadgets, snacks, or company. Simply stated, if you’re going to hang out 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 accommodating and upscale.

Is a California King Mattress for Me?

You may choose a California king if you:

  • Are tall and need more leg room in your bed
  • Have a narrow space for your bed and you don’t want the room to feel crowded
  • Have a pet that likes to sleep at the foot of your bed; the extra length ensures there’s room for everyone to be comfortable
  • Have a generous mattress budget, because California king mattress are typically more expensive
