Space cotton, also known as polyurethane slow resilience sponge, was developed by NASA in the 1960s. It is an open cellular structure with the characteristics of temperature sensitive decompression. It can also be called as a temperature sensitive decompression material.

This material was used on the shuttle. In order to relieve the pressure on the astronauts, to protect the astronauts' spines, especially the shuttle during the return and departure of the astronauts suffered the most pressure is the most dangerous. In order to protect the safety of astronauts, the material was invented.

He is one of the two great inventions of space technology, along with the global positioning system (GPS). Sleep at night when the pillow on the top of the feeling as if floating in the water/or cloud, the skin feels like no pressure; Also known as zero pressure, sometimes we will have pressure on auricle when using ordinary pillows, but the use of polyurethane slow rebound sponge will not have this situation, and according to ergonomic design, the ability of memory deformation, automatic molding can fix the head, reduce the possibility of stiff neck.

The ability of automatic shaping can properly fill the shoulder space, avoid the common problem of air leakage in the shoulder quilt, and effectively prevent cervical spine problems. After decades of development, space pillow has formed a very mature market in China and spawned a large number of enterprises.
