Reversible multi-layer mattress pad

Abstract

In some embodiments, a reversible multi-layer mattress pad comprises a first layer, a second layer, and a third layer. The first layer comprises a first temperature-sensitive memory foam having a first density suitable for warmer temperatures, and the second layer comprises a second temperature-sensitive memory foam having a second density suitable for cooler temperatures. The third layer comprises a form-supporting form layer disposed between first and seconds layers (e.g., forming a three-layer “stack”).
