TEMPUR® pressure-relieving materialTM is a breakthrough in sleep technology that will forever change the way you sleep. The original formula was developed in the early 1970's at NASA's Ames Research Center in an effort to relieve astronauts of the incredible g-forces experienced during lift-off. Fagerdala World Foams of Sweden spent almost a decade and millions of dollars researching and experimenting with the NASA material before discovering a way to produce a consistent and durable product.
The cellular structure of the TEMPUR® pressure-relieving materialTM is completely different. It's made up of billions of high density, viscoelastic, memory cells. The cells are spherical with windows, and the key is..they're temperature sensitive. The high density of TEMPUR® pressure-relieving materialTM makes the Tempur-Pedic Swedish MattressTM so durable that it's backed by an incredible 20-year limited warranty. In warm areas, they get softer and pliable. In cooler areas, they stay firm. The cells will literally shift position and reorganize to conform to your body contours. The cells shift so you don't have to. Imagine a mattress that's firm where you need it and soft where you want it. It's like having a mattress custom designed to fit your body.
