1800 Series Split Top California King Sheets for Adjustable Beds

FAQ's

What is a Split Top California King sheet?

Split Top California King sheets (also called Flex Top Cal King sheets) are made for mattresses where the top portion is split but the bottom remains connected. This allows independent head adjustment on an adjustable base.

What’s the difference between Split California King and Split Top California King?
