Collection: Split California King Mattresses

A split California king is made of two narrow mattresses, each 36 by 84 inches, that sit side by side, usually on an adjustable base so each sleeper can raise or lower their own side. Nearly all of ours are hybrids, with foam over springs, and more than half use gel memory foam, some infused with copper or graphite. Thickness runs from 7 to 16 inches, most often 10 to 14. Half are plush, and the rest split between medium and firm. Check each listing for whether it covers one side or the pair.
