Patent ID: 8918931

Claim:
A bed accessory for use with a bed having a mattress and a base for the mattress, said accessory comprising: a bed cover retainer having a first portion adapted to fit between the mattress and the base for the mattress and a second portion that is configured to extend outwardly of the mattress and the base for the mattress; said first portion defining a wedge wherein said wedge comprises first and second members that are portions of a unitary member and joined together at one end portion and movable toward each other and a bias, said bias biasing said first and second members away from each other when moved toward each other thereby producing a separation force when inserted between the mattress and base tending to hold the retainer in position and the bed cover against the mattress; said first portion defining an outwardly extending high-friction surface on at least one chosen from said first and second members wherein said high-friction surface provides a higher resistance to a motion in one direction than to a motion in an opposite direction wherein resistance to a force positioning said first portion between the mattress and the base for the mattress is lower than a force retaining said first portion between the mattress and the base for the mattress; and said second portion defining flanges on said first and second members that face away from each other and return inwardly toward said first portion to fit around any ribbing around the mattress and the base.
