Abstract
Stacked object slippage prevention apparatus includes two rigid retainers each having a straight portion and an angled portion at an angle of 80-115 degrees to the straight portion, and a connecting element connected at opposite end regions to the retainers. The connecting element may be a strap and a pair of fixing elements, one at each end region of the strap, and which are adjustable relative to the strap to provide the strap with an adjustable length to fit different sized beds. When installed, for example, between a mattress and an underlying support, with the angled portion of the retainer at the foot of the bed oriented upward and the angled portion of the retainer at the head of the bed oriented downward, movement of the mattress toward the foot of the bed is prevented by pressure applied to the support being transferred between the retainers through the connecting element.
