TEMPUR

Tempur is a brand name used for a line of viscoelastic polyurethane foams marketed for bedding and cushions. The material, commonly marketed as TEMPUR foam, originated from research conducted by NASA into seating and impact attenuation in the 1960s–1970s and was later licensed for consumer products.

Tempur-Pedic International popularized the material in the 1990s with mattresses and pillows designed to conform to the sleeper’s body and reduce pressure points. The foam is high-density and temperature-sensitive; it becomes softer with body heat and gradually returns to shape when cooled, providing contouring support and reduced motion transfer.

Critics point to heat retention, potential off-gassing, and premium pricing. Supporters note improved pressure relief and stable support for various sleeping positions, along with better isolation of movement between sleep partners.

In 2013 Tempur-Pedic International merged with Sealy Corporation to form Tempur Sealy International, the company that markets the TEMPUR brand worldwide. The TEMPUR trademark is owned by Tempur Sealy International and is used on mattresses, toppers, pillows, and related bedding products across markets. Variants of TEMPUR foam have evolved, with newer formulations claiming improved cooling, responsiveness, or durability while preserving the core memory-foam characteristics. The term Tempur may also appear in regional product lines or corporate naming, but remains closely associated with the high-density memory-foam material used in a range of bedding products.
