Spa cover support and storage unit

Abstract

A device for supporting a spa cover after it has been removed from the top of a spa tub. The support is free-standing and contains one or more support devices, such as two or more rollers, onto which the spa cover is pushed or pulled. The support includes a storage area for spa accessories and other implements.
