Why choose REM-Fit?

Tall Pocket Springs

Premium Pocket Springs

Through rigorous testing, our sleep researchers found that springs below 8cm in height provided inadequate support and failed to isolate partner movement. For undisturbed sleep & superior support, REM-Fit mattresses only use tall, authentic pocket springs 14cm-16cm high.

Weightless Pressure Relief

Our Mediflex memory foam layer which sits beneath our cool-gel infused memory foam layer is designed to gently absorb the weight of your body. This, coupled with our hypoallergenic stretched outer fabric, results in what is often described as a feeling of weightlessness.

Cool-Gel Infused Foam

Cool-Gel Memory Foam

Our unique layer of cool-gel infused memory foam provides advanced temperature regulation as well as supreme comfort. Overheating during sleep is one of the key reasons for unexplained waking during the night, disturbing our sleep cycles and affecting our overall rest & recovery.

Tired of Sleeping Hot?

Tired Of Waking Up Sore?

A next-generation orthopaedic hybrid mattress combining 2000 firm, orthopaedic pocket springs, with cool-gel infused memory foam for unrivalled orthopaedic support, temperature control and supreme comfort! Trial For 100-Nights.

Why are REM-Fit springs superior to your counterparts?

Unlike our counterparts we use tall pocket springs constructed from triple tempered steel. Each springs is contained within it's own pocket of fabric which prevents the spring system from rubbing against each other, nothing worse than a squeaky mattress! Tall pocket springs compared to mini springs provide superior support and will isolate partner disturbance movement more effectively. And don't worry about feeling the springs through the mattress, you can't, we place them deep beneath the top layers of the mattress so that they are never noticeable.

What base can the mattress go on?

Thanks to the high density foam layer of the mattress you can confidently use the mattress on any bed base including adjustable beds!

I have a bad back - will the 500-Ortho model help?

As non medical professionals we make no guarantees that the mattress will improve your back complaint. However, we have designed our mattress range with a focus on back support, the 500 Ortho being our recommended mattress for back sufferers. We have also received lots of positive feedback from sleepers who have suffered with a bad back to discover that sleeping on a REM-fit has relieved their pain and enabled them to get a great night's rest.
