California King mattresses are ideal if you're seeking additional length in your sleep surface. They offer the extra length you need by reducing the width of a traditional King mattress by 4".

Visit any of our 8 store locations to purchase a CA King mattress from premium manufacturers or our private label brand. We offer a variety of comfort levels and types, including innerspring, foam, TEMPUR-Material, hybrid, gel and latex mattresses.

Please note: All California King mattress purchases are subject to California recycling fees. The standard CA King mattress dimensions of 72" wide by 84" long are approximate and may vary by up to ±1 ½" due to the handcrafted nature of manufacturing. Measurements are taken from the bottom of the mattress or foundation, edge to edge or side to side.
