what is memory foam？
Memory foam is a polyurethane that’s treated with other chemicals to make it soft to the touch, compressible, plastic and elastic. I use plastic and elastic in the chemical sense – see you knew that chemistry you did at school would come in handy one day!
As a little reminder, plastic means the ability to change in shape if force is applied. Elastic means the ability to return to its original shape after an applied force is removed.
Different density foams and various chemicals used in manufacture will affect its properties such as how soft it feels, how much it compresses, how quickly it returns to shape and its durability.
