Memory foam mattresses are becoming more and more popular these days. Many people are wondering if it’s safe to cut them in half or cut them down to a smaller size. In this article, we will explore the facts and answer that question for you.

What is Memory Foam?

Memory foam is a type of visco-elastic material used by a variety of industries. It is used in a variety of ways, from home mattresses to hospital beds. To understand memory foam, it is necessary to understand visco-elasticity.  

It was developed in 1966 by NASA engineers in response to their discovery that astronauts were sleeping poorly in space. The visco-elastic foam material was eventually adapted for use in mattresses.

Visco-elastic materials are those that have both viscous and elastic properties. Some examples of this include rubber, hair, and Jell-O. The memory foam is made from a visco-elastic material called polyurethane.

A mixture of chemicals, some of which are man-made, and others that are natural, is mixed with polyurethane to create a foam that is unique in its ability to both conform and bounce back.  This is the same material that most mattresses are made out of, and the same material that is used in the soles of shoes.
