Description

The TEMPUR® One Firm Mattress is the embodiment of TEMPUR®’s scientific advancements. An open cell structure responds to your body’s weight and warmth, constantly adapting to your unique needs, softening the mattress at your heaviest pressure points.

Technology derived from space

Firm visco-elastic cells provide you with full body support and pressure relief as you sleep. Adapting to your individual needs, these billions of spherical open cells contour to your body, continuously rearranging to support your body as you body changes in temperature, weight and movement.

These cells ensure the mattress gets slightly softer where your heaviest pressure points arise, so you feel extra support exactly where you need it.

The TEMPUR® ONE Firm Mattress contours to your unique body shape, without you feeling completely sunk in. You’ll feel supported, comfortable and tailored to with TEMPUR® Support Material offering you a firm and reliable sleep surface.

Derived from the material NASA uses to cushion astronauts in space, TEMPUR® Support Material ensures complete adaptive comfort as well as motion absorption. This means you won’t be disturbed by a partner in the night, with the TEMPUR® ONE Firm Mattress adapting uniquely to your individual needs.

A cool, refreshing night’s sleep

While regular memory foam is known for its heat retention, the TEMPUR® ONE Firm Mattress offers enhanced ventilation, encouraging air circulation throughout the mattress. Not only does this keep you cool and refreshed throughout the night, but creates a healthier sleeping environment, too.

An easily removable mattress cover allows you to clean away any spills quickly, increasing the TEMPUR® ONE Firm Mattress’ lifespan. A true staple of Danish design and honest craftsmanship, this mattress comes with a ten year manufacturer’s guarantee.
