Memory foam is a visco-elastic polyurethane foam that is resilient. It is so soft and light, but it can be firm under your head and extremely durable. It is dense, yet yielding. And it feels so right when it is under your head as a pillow. The memory foam is temperature-sensitive and it jumps back to its original form as you lift your head from it. No other pillow, be it down, feather, synthetic or conventional foam, can beat its advantage of being so soft and yet so supportive.
