Abstract: The present invention relates to mattress or furniture insulator pads that are placed between the coil springs and the cushioning material in mattresses or furniture, such as chair seats. Such insulator pads prevent the springs from piercing the furniture cushion and provide a bridge across the springs to more evenly distribute weight over the springs.

Most preferably, a five layer insulator pad has the polyurethane foam sandwiched between stiffening layers and also has outer layers of polyurethane foam, applied adjacent to the stiffening layers, forming the top and bottom surfaces of the pad. Such outer layer foam sheets provide friction characteristics that retard relative movement between the cushion and the springs.
