Ashley offers various California king mattresses, including memory foam and innerspring, to suit your comfort preferences. Whether comparing king sizes or checking frame compatibility, Ashley provides guidance and a range of options to help you choose the right mattress for your needs and space.What is a California King Mattress?

Dimensions and ComparisonCalifornia King:
- 72 inches wide × 84 inches long
- Total sleep area: 6,048 square inches
- 76 inches wide × 80 inches long

How much is a California king mattress?
California king mattress prices are determined primarily by features and materials rather than size. On Ashley, California king mattresses start at $250 and can exceed $2,500, depending on the model.Basic all-foam or memory foam California king bed mattresses are typically available from $250 up to $1,200, offering pressure relief and straightforward shipping.
Hybrid options, which combine coils with foam or latex, generally range from $1,300 to $2,500 and offer added support along with improved temperature regulation.
Luxury mattresses featuring organic latex, smart technology, or advanced cooling designs often cost $2,500 or more.
Note: Mattress prices vary by location and store.
Do I need a box spring or foundation for a California king mattress?
No, you do not always need a box spring or foundation for a California King mattress. It depends on your bed frame type and your mattress warranty requirements.If your bed frame is a simple metal frame with only minimal cross supports, you will need a foundation. Foundations use solid wood or metal slats, providing even, sturdy support that prevents sagging and protects your mattress warranty.
Platform beds with a solid surface or slats no more than 2.75–3 inches apart do not require a box spring or separate foundation, these provide adequate support on their own. Using a foundation with a platform bed is unnecessary and only adds extra height.
Adjustable bases serve as both frame and support, so they do not require an additional foundation.
Always check your mattress warranty details. Most warranties require strong, consistent support across the mattress.
Are California king mattresses compatible with adjustable bases?
Yes, California King mattresses are compatible with most adjustable bases. When shopping, ensure that the adjustable base is specifically designed to fit California King dimensions, which are longer and narrower than standard King sizes. Always verify manufacturer guidelines to avoid sizing or warranty issues.Do two twin mattresses make a California king?
No, two twin mattresses do not equal a California king. Two twin xl mattresses placed side-by-side create a standard king. To create a split California king, you must purchase specific "split Cal king" mattresses.Where can I buy a California king mattress?
