	How it works: Three special properties, high density and weight, slow rebounds and temperature sensitive, makes memory foam comfortable to human bodies. Having higher density and weight than most foam, memory foam provides a thick layer of soft and very supportive cushion to pressure areas. With slow rebounds, the support from memory foam is soft and yet uniform. The feel of the support is unlike most foam, which is either too hard-and-stiff or too soft-and-flimsy. The example of a hand impression in the foam is often used to demonstrate this property. Different from other type of foams, memory foam senses the ambient temperature, and adjusts its physical property to become firmer in cooler temperatures and softer in warmer temperatures. As result memory foam reacts to body heat, allowing it to gradually mould itself to the shape of a warm body within a minute or so. That is how memory foam can provide a uniform support throughout the entire pressure area, leaving no soft spots or weak supports anywhere in contact with the foam.
