When NASA released the material’s formula for consumer use, our founders were eager to improve the application specifically for sleepers. Our scientists rigorously tested and enhanced the foam to increase its adaptability, heat dissipation, and durability.

For more than 25 years, Tempur-Material™ has evolved to give you a sleep experience like no other. Unlike memory foam, our material is uniquely formulated to respond to your body’s weight, shape, and temperature.

The material’s viscous (fluid-like) and elastic (spring-like) properties actively work together to provide the proper support, comfort, and infinite adaptability.

The result? Unparalleled pressure point relief, absorption, and motion separation to help keep you in uninterrupted, deep sleep. That’s why no other material performs like Tempur-Material™.
