Geltex Inside Guide

Sleep better, wake up brighter

Sleep better, wake up brighter

Geltex is our patented gel infused comfort filling that’ll leave you feeling energised and rejuvenated every morning.

It’s highly elastic and flexible, creating a ‘bounce-back’ profile to assist free movement through the night for an undisturbed sleep, while offering optimum pressure relief where you need it most. 

It also comes with an intelligent open cell structure, allowing air to pass through for a fresher, more breathable sleeping environment.

Better sleep, backed by science

Better sleep, backed by science

It's easy to make bold claims - so we thought we'd let science do the talking.

We teamed up with the University of Central Lancashire to conduct a series of scientific studies involving Geltex and standard foam mattresses.

Results have shown that Geltex delivers everything you need for a fantastic night's sleep, including greater pressure relief and improved support providing a reactive bounce back feel for the ideal sleeping environment.
