Invented by NASA in 1966 to improve the safety of aircraft cushions, today Memory Foam is widely used because of the sensation it creates of “sinking in” to a mattress and being cradled. When you press your bodyweight onto this kind of cushion, you’ll find that it takes on your shape and slowly bounces back once you remove the weight. It provides ideal support, excellent pressure relief, proper spinal alignment and it limits partner disturbance.
