Caption: Memory foam (open cell foam). This type of foam is often used for pillows, mattress coverings and for various cushioned devices for medical purposes. The initial memory foam, known as T-foam, off gassed too much for use in a closed environment, especially by the space industry. Memory foam is an open cell foam (cells of the foam have holes in them) that compresses fully and the air pressure is spread to adjoining cells thus causing the foam to slowly revert to its original form.
