Upholstery Layers

Same as padding layers or comfort layers, these are foam or fiber layers that are added on the top of the support system to provide overall comfort level and softness of the mattress. Manufacturers use different shapes, amounts and densities of padding materials (polyurethane, gel, latex and memory foams, polyester, cotton, wool, cashmere) to achieve varying levels or softness. Pillow top models, being the softest, have a larger amount of padding layers on the top, while firm models have only a few layers.
