TEMPUR PRO® SmartCool™ Medium King Mattress

The only mattress brand recognised by NASA¹ and certified by the Space Foundation². At the heart of each mattress and pillow we create is our iconic TEMPUR^® Material, born from NASA technology. In the late 60s, NASA scientists invented a completely new material that was then used onboard the Space Shuttles. Our founders realised the material’s unique potential. So they took that original NASA invention and spent years perfecting it into TEMPUR^® Material and created the world’s first viscoelastic mattress and pillow.

¹ The company and its products were recognised by NASA. At a joint press conference on May 6, 1998, NASA recognised TEMPUR®’s outstanding achievements in adapting the original NASA technology for everyday use and improving the quality of life for humankind.

² Tempur products are certified as "Certified Space Technology" by the Space Foundation, an American non-profit organization, because they contain technologies originally intended for space. Further information about the Space Foundation and its Certified Space Technology program can be found at www.sg.tempur.com/spacefoundation.html
