What is Memory Foam? History, Types and Benefits

What is memory foam

Memory foam is a composition of viscoelastic foam, a synthetic material. Soft and long-lasting, it helps sleepers with back pain and eases joint pain.

If you are fond of space technologies, you will know what memory foam is. This temper foam, formerly known as memory foam (the most popular), was developed under a NASA contract.

NASA was looking for a foam that could help release the takeoff stress for astronauts and improve cushioning.

It is the most popular type of foam in today’s world and is used in making mattresses, pillows, toppers, and blankets.

It also comes in varying firmness levels, so you can select what suits how you sleep.
