TEMPUR® Mattresses

TEMPUR® mattresses are science orientated. When NASA first started using a special pressure-absorbing material to cushion their astronauts during take-off, TEMPUR® took this material and developed it into something that would completely transform the mattress world. A cut above the rest, a TEMPUR® mattress will have you feeling so weightless, you’ll feel like you’re in space.

What is special about TEMPUR® mattresses?

TEMPUR® mattresses are the pinnacle of cutting-edge design. Using an advanced pressure-absorbing material, first used by NASA and developed by TEMPUR®, these mattresses offer incredible levels of support and comfort.

With consistent reliable support, night after night, TEMPUR® mattresses have an open-cell structure that specially contours to your individual body shape. No matter your shape, weight or size, a TEMPUR® mattress will find your unique pressure points and support them, leaving you with a feeling of weightlessness. 

TEMPUR® mattresses are suitable for all kinds of sleepers, no matter if you sleep on your front, back or side. The magic of TEMPUR®’s advanced version of memory foam is that it will help you find your most comfortable sleeping position and support you there, leaving tossing and turning throughout the night a thing of the past.

First exclusively made for healthcare and medical purposes, TEMPUR® Material has taken the world by storm, as millions of worldwide customers enjoy the orthopaedic levels of support and comfort from their TEMPUR® mattress.

What makes TEMPUR® Material different from memory foam?

Ordinary memory foam tends to retain heat for a long time, leaving you sweaty and uncomfortable during the night. It also stays compressed after pressure is applied and removed, reducing the cushioning effect it’s supposed to give.

TEMPUR® Material has a specially designed open-cell structure that not only enhances ventilation, but prevents sagging and compression.

These billions of visco-elastic, spherical shaped, open cells are constantly re-organising themselves to react to your body’s temperature and weight. This makes your TEMPUR® mattress softer where your body is heaviest and where the most heat is detected.

What materials are TEMPUR® mattresses made from?

First used by NASA to cushion their astronauts during take-off into space, the special pressure-absorbing material used to make TEMPUR® mattresses so unique has been extensively developed and advanced by scientists to create the most advanced viscoelastic polyurethane foam the mattress world has ever seen.

By using billions of ultra-sensitive open cells existing between a solid and liquid state, TEMPUR® Material is viscoelastic, meaning it’s both fluid and spring-like. The result? Proven pressure relief that is guaranteed to provide your body with total support and comfort.

Are TEMPUR® mattresses hypoallergenic?

All TEMPUR® products are finished with a soft, removable cover that is both antimicrobial treated for improved freshness and hypoallergenic.

How long do TEMPUR® mattresses last?

Like any mattress, you should start to think about replacing it at around the 8 year mark, as this is where you'll begin to see sagging and other irrepairable damage. So long as you look after your TEMPUR® mattress properly, it will last a long time, so you can enjoy thousands of restful nights.
