Our products are made of NASA contriving material (high density visco-elastic polyurethane foam with an open cell structure) which has pressure relief characteristics. Can help relieve headache, neck ache, spine ache as well as backache.

The product material is sensitive to change of temperature. When temperature rises, it will become soft and vice versa. When in contact with body heat, the surface particles will be softened, thus can mold to user body shape and release pressure evenly. Material will return to original condition when it is away from body heat.

However, if it becomes softened abnormally, please check if it has been exposed to sunlight/heat for a long period.
