California King Size Mattresses

A California King mattress is 72 inches wide by 84 inches long (6 feet by 7 feet), or approximately 182.9 cm x 213.4 cm. It is the longest standard mattress size available in the US—4 inches longer and 4 inches narrower than a standard King. Also commonly called a Cal King, it is designed specifically for tall sleepers.

Leesa offers a limited lifetime mattress warranty that covers the following:

• Deterioration of the mattress resulting in a visible indentation greater than one and a half (1.5) inches that is not associated with an indentation or sag as a result of an improper or unsupportive foundation or base.
• Any physical flaw in the craftsmanship of the mattress that causes permanent damage to the memory foam despite proper set-up and normal use.
• Any physical flaw in the craftsmanship of the cover, including seams and zipper assembly.

Please see our warranty page for full details, terms & conditions.

Every Leesa mattress comes with a 120-night trial. After 30 days of sleeping on your new mattress, if you're not happy with your purchase, the friendly folks on our Comfort Crew can help walk you through the process of returning and refunding.

Whenever possible, we donate any returned mattresses to a 501(c)(3) organization or one of our charity partners. One of Leesa's missions is to be a positive force in the world, so if we can donate a mattress in good condition rather than disposing of it in a landfill, that's the route we're going to take.

A standard King is 76 inches wide by 80 inches long. A California King is 72 inches wide by 84 inches long—4 inches narrower but 4 inches longer. The standard King is the better choice for most couples who want maximum width. The California King suits very tall sleepers (over 6 feet 4 inches) who need the extra length more than the extra width. Standard King bedding, frames, and accessories are more widely available than California King equivalents.

Yes. Cal King is simply a shortened name for California King—both refer to exactly the same mattress size: 72 inches wide by 84 inches long. You will see both terms used by retailers, bedding manufacturers, and frame makers. If a product is labeled Cal King, it is built for a California King mattress.

A California King is best suited to sleepers over 6 feet 4 inches tall who regularly feel length-constrained on a standard mattress. At 84 inches long, a Cal King gives sleepers up to approximately 7 feet tall full room to stretch out. For sleepers under 6 feet 4 inches, a standard King typically provides more practical benefit through its additional 4 inches of width.

Yes, for tall couples. A Cal King gives two adults 36 inches of personal sleeping space each at 72 inches wide—2 inches less per person than a standard King, but 4 inches more length for both. For couples where at least one partner is over 6 feet 4 inches, the Cal King's length advantage outweighs the narrower width. For couples of average height who want maximum shared width, a standard King is the better fit.

A California King fits most comfortably in a room of at least 12 x 14 feet. Because a Cal King is 84 inches long—4 inches longer than a standard King—it needs additional clearance at the foot of the bed compared to a standard King in the same room. In rooms smaller than 12 x 12 feet, a Cal King will limit clearance more than a standard King would.

A California King mattress is 72 inches wide by 84 inches long, or approximately 182.9 cm by 213.4 cm. For comparison, a standard King is 76 inches wide by 80 inches long. Leesa California King mattresses range from approximately 10 to 13 inches in height depending on the model. See our sizes & weights support article for more information.

No. California King sheets, duvets, and comforters are sized for a 72" x 84" mattress and will not fit a standard King (76" x 80") correctly—they will be too long and too narrow. Always confirm your mattress size before buying bedding. Cal King-specific bedding is available from most major retailers but is less widely stocked than standard King equivalents.

No. A California King is a different size from a standard King and requires a Cal King-specific frame. Standard King frames are 76 inches wide and 80 inches long—a Cal King mattress at 72" x 84" will not fit correctly in a standard King frame. When purchasing a frame, headboard, or adjustable base for a Cal King mattress, confirm it is explicitly sized for California King.

California King mattresses are typically priced similarly to standard King mattresses at equivalent quality levels. The more significant cost consideration is accessories: Cal King-specific bed frames, sheets, and duvets can be less widely available and occasionally more expensive than their standard King counterparts. Factor in the full bedding setup cost when budgeting for a Cal King.

Leesa California King mattresses are available across a range of price points depending on construction and features. Every model ships free and comes with a 120-night trial and a limited lifetime warranty. Visit the individual product pages for current pricing.

For tall sleepers, a hybrid Cal King often performs better over time. Hybrid constructions with individually wrapped coils provide more consistent edge-to-edge support across the longer 84-inch surface, which matters when a tall sleeper uses the full length of the mattress. Memory foam Cal Kings offer excellent pressure relief and motion isolation, which suits lighter sleepers or couples where one partner is sensitive to movement. The Mattress Quiz can help identify the right construction based on how you sleep.
