Gel Memory Foam
Memory Foam Mattresses & Beds
Memory foam mattresses are more supportive than other types of beds, as well as being more dense and heavy. As it reacts to body weight and heat, memory foam alleviates pressure points by molding itself to the sleeper, like an infinite number of small springs, and it also allows little to no motion transfer and bounce. Memory foam was developed by NASA in the 1970s for flight comfort and crash safety.
