From clinical research • exercise physiology
Your mattress absorbs around 200 litres of sweat every year.
The body produces up to 700ml of sweat during a single night's sleep. Without a protector, every drop goes directly into the mattress - along with the skin cells that feed up to 10 million dust mites. The Tencel Cool Protector creates a washable, cooling barrier between you and your mattress.

The REM-Fit Tencel Cool Mattress Protector won Good Housekeeping's Best Cooling Protector award in 2026, thanks to silent Tencel fibres that wick moisture away from the body while you sleep. A Miracle Membrane barrier sits underneath to protect against dust mites and allergens, and the whole protector is designed to stay quiet, smooth and cool against the skin all night.
Who is it for?
Suited to hot sleepers and anyone who finds standard cotton or polyester protectors trap heat overnight. The wicking Tencel fabric makes it a good match for warmer bedrooms or sleepers who tend to overheat.
What makes it different?
Unlike standard waterproof protectors, the Tencel fibres actively wick moisture rather than just sitting on top of the mattress, which is what helped it win Good Housekeeping's cooling protector award. It also stays genuinely silent during movement, where many waterproof protectors rustle. Pairs well with any REM-Fit hybrid mattress to help protect your sleep trial and guarantee.
