California King mattress questions, answered.

How big is a California King mattress?
California King is typically 72 × 84 inches, 4 inches longer and 4 inches narrower than standard King. Check exact mattress and frame measurements using the size guide.
Is California King bigger than King?
It is longer but narrower than standard King, not larger in every direction. Standard King is typically 76 × 80 inches. Choose the dimensions that suit your space. Compare King mattresses.
Will King sheets or a King frame fit?
Do not assume King and California King frames or fitted sheets are interchangeable. Verify dimensions, support requirements and fitted-sheet depth. Check the mattress size guide.
How does the comfort exchange work?
Eligible mattresses qualify for one same-size comfort exchange after at least 30 nights and within 120 nights of delivery. There is no exchange fee. Bring the mattress back and pick up the replacement yourself at no charge, or choose pickup and redelivery by our team for $100 total. Pay any increase for a higher-priced replacement; there is no refund of the difference for a lower-priced one. Conditions and exclusions apply. Read the comfort-exchange terms.
Can I try it in a showroom?
Call ahead to confirm which models and sizes are available to try at your preferred location. Online availability does not mean the same size is on display. Choose a showroom.
