About Cal King Mattresses

California king beds, also referred to as “Cal king,” are the biggest of all the standard mattress sizes. This size can help balance out a space because of its unique dimensions since the design is less square. Cal kings have become a popular option for couples. It might not be a great option for those who sleep with kids or pets, though, since it is slightly narrower than a standard king. However, this is a great option for tall people. Couples who like to snuggle will also prefer a California king mattress rather than spreading out. You can also purchase a split California king that allows you and your sleep partner to select different comfort levels or use separate adjustable bases.

Check out our selection of Cal king beds, including California king size mattress sales. Each of our California king mattresses on sale come with a 120-night comfort guarantee and a manufacturer warranty. We also carry a selection of Cal king bedding accessories to help complete your sleep setup.

98% Customer Satisfaction

Why our customers love BedMart

Came in looking for a new bed, and I had no idea what I was looking for. Keith helped us and we were pleasantly surprised with how much knowledge he had in beds! He knew the kind of bed for side/back sleepers, for back pain, and even to help with my husbands acid reflux! We spent some time in there asking questions & he patiently helped us with all our concerns.
