Our Selection of California King Mattresses

The California King bed size is ideal for people who like lots of room when they sleep. The bed’s California King Size Mattress, which is sometimes called a Western King or Cal King mattress, is available in several brands and construction types. Averaging 72 inches in width and 84 inches in length, the California King mattress size offers a full 42 square feet of luxurious sleeping surface.

The California King Size bed came on the market in 1950 as larger houses and bedrooms gained in popularity. People who bought those homes also frequently bought a Cal king size bed and mattress combination. More than 75 years later, a Cali King mattress size is still popular among:

  • Taller people, who need plenty of room to stretch out when sleeping
  • Family members who share a bed due to limited bedroom space
  • Moms who enjoy cuddling in bed with their younger children
  • Families whose dogs or cats have made a habit of sleeping on the bed
  • People who enjoy marathon television watching, eating or working on laptops while in bed

Sit ‘n Sleep’s huge selection of top quality mattresses and bedroom furniture make us the go-to place in Southern California for a California King mattress size. Among the many name brands we offer are Sealy, Beautyrest, Sherwood, Tempur-Pedic, Aireloom and more.

  • Memory Foam: Developed by NASA during the ‘70s to reduce gravity’s effects on astronauts, a Cali King Size memory foam mattress will gently mold itself to your body’s contours and evenly distribute your weight to comfortably support your neck, back and shoulders. Because they absorb motion transfer, a California King bed size with a memory foam mattresses will let one sleeper move about without disturbing the other.
  • Hybrid: A Hybrid mattress combines innerspring technology topped off with a layer of memory foam mixed with latex or gel. The result is a relaxing blend of comfort and support that will leave you relaxed and refreshed ion the morning.

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.
