Abstract
Abstract A reliable fastener to quickly and easily secure a flat sheet around the mattress of a bed, particularly a water bed, to prevent an inadvertent removal of the sheet from the mattress. First and second complementary pieces of adhesive material are arranged at each of the corners of the sheets and at areas of the bed frame over which the mattress corners are laid. A pocket is associated with each of the sheet corners to enable the user to insert his hand therein and guide a first piece of adhesive at the sheet corner into mating and releasable engagment with a second piece of adhesive at the bed frame.
