What the Sleep Expert thinks...

"ONE Medium is my “just-right” pick. NASA-born TEMPUR Material senses heat and weight, softening at pressure points while maintaining buoyant lift elsewhere. Continuous ventilation prevents heat build-up, and motion-absorbing cells let partners sleep peacefully. It’s an effortless, weightless experience for every sleep style."

Description

The TEMPUR® ONE Medium Mattress is driven by science. Featuring TEMPUR® Material derived from NASA, the open-cell structure of this mattress offers exceptional, unique support and comfort.

Softens at your heaviest pressure points

Billions of visco-elastic, spherical open cells work continuously within the TEMPUR® Support Material of the TEMPUR® ONE Medium Mattress.

Adapting to your changes in temperature and weight, these cells respond to your body, softening the material where it detects your heaviest pressure points. The result? A weightless feeling that’s as supportive as it is comfortable. It’s pure science.

Let the TEMPUR® ONE Medium Mattress contour to your unique shape, cradling you in comfort and personalised support as you sleep.

Unlike regular memory foam, this open cell structure allows continuous airflow throughout the TEMPUR® ONE Medium Mattress, so you don’t suffer from overheating due to heat retention.

Leave disturbed sleep in the past

Motion absorbing properties ensure you won’t be disturbed by a wriggling partner in the night. As the innovative TEMPUR® Support Material springs back to life after pressure is removed rather than compressing like regular memory foam, you can enjoy reactive support night after night no matter how you choose to sleep.

No maintenance required, the TEMPUR® ONE Medium Mattress comes with a removable zip cover that you can simply pop in the wash when needed. No need to flip or turn - TEMPUR® Support Material doesn’t need refreshing to work like new.
