A California King size mattress is 72" wide by 84" long, 4 inches narrower and 4 inches longer than a standard King (76" × 80"), making it the longest stock mattress size we sell and the right pick for sleepers over 6'2" or bedrooms that are deeper than they are wide. Every Cal King on this page ships with free next-day white-glove delivery anywhere in Los Angeles on orders over $499, a 120-night Love Your Bed Guarantee, and 0% APR financing on orders of $1,500+. Not sure between King and Cal King? The width-vs-length trade-off is the whole decision, see the guide below or lie on both at any of our 5 LA showrooms.
A California king is 72 by 84 inches, four inches narrower and four inches longer than a standard king. It suits sleepers over six feet and rooms that are long rather than wide. Bedding and bases are sold separately in this size, so check that the base or frame you already own is a California king before you buy the mattress.
Part of the Labor Day mattress sale. Other sizes: king, queen, twin, twin XL and full. Shop by type: hybrid, memory foam, latex and Tempur-Pedic.
A California King mattress measures 72" × 84" (6 ft × 7 ft). It's 4" longer than a standard King but 4" narrower, the right pick for taller sleepers (over 6 ft) and long-narrow bedrooms where the extra length matters more than the extra width.
What pairs with a California King. Cal King bedding is its own size and runs slightly more expensive than King bedding because of lower demand. Most adjustable bases offer Cal King as a single-piece unit or as Split Cal King (two 36" × 84" halves) for couples with different sleep needs. See our adjustable beds collection for compatible bases.
Room sizing. Minimum bedroom for a Cal King is 12 × 14 ft, the bed itself takes 6 × 7 ft and you need ~24" walk-around space on three sides. If your bedroom is wider than long, a standard King (76" × 80") fits the geometry better. See the full mattress size chart for every size compared, including the dimensions in feet, inches, and centimeters.
Every California King mattress on this page ships with free next-day white-glove delivery across Los Angeles on orders over $499, an optional $100 same-day upgrade if you order by 4 PM, and the 120-night Love Your Bed comfort exchange so you can swap firmness if it isn't right at home.
California king is the right pick if you or your partner is 6 feet tall or taller, its 84" length gives you 4 extra inches of foot room compared to a standard king or queen. The trade-off is 4" less width than a standard king (72" vs 76"). For couples under 6 feet, a standard king is usually the better fit.
Slightly. Most home stores carry standard king bedding by default, with Cal King as a special-order. We stock Cal King sheets, fitted sheets, and mattress protectors at every showroom, and our online sizing page lists which models are available in Cal King.
Yes, Cal King bed frames and foundations are sized specifically (72" x 84"); a standard king frame is too wide and too short. Most major brands offer both king and Cal King variants of every bed frame, foundation, and adjustable base. We confirm frame compatibility before delivery so you don't end up with a mismatch.
