In general, MOST foam play flooring / mats are made with a material called EVA (ethylene vinyl acetate) which is a foam rubber compound. For a while now it has been viewed as a healthier alternative to PVC and the process of making it excludes the use of chlorine which can produce carcinogenic compounds called dioxins.
Memory foam is a special type of material which reacts to pressure and temperature causing it to mold and conform to shape accordingly. Therefore when it comes to sleeping on bed pillows, the foam creates a mold around the shape of your head, neck, shoulders, ears and any other body part which it comes into contact with. The traditional and most common type of foam is polyurethane, also known as viscoelastic foam.
