We also receive lots of positive feedback from sleepers who have suffered with a bad back to discover that sleeping on a REM-Fit mattress has relieved their pain and enabled them to get a great night's rest.

Tired of Sleeping Hot?

REM-Fit memory foam benefits from a revolutionary open-cell construction keeping it cool!

Proven to wick moisture and dissipate heat away from the body keeping your sleep environment at just the right temperature

Why Choose The 600 Lux Mattress?

4000 Premium Pocket Springs

Through rigorous testing, our sleep researchers found that spring systems below 8cm in height provided inadequate support and failed to isolate partner movement. For undisturbed sleep & superior support, the 600 Lux uses a 15cm tall dual spring system layer comprised of 4000 premium pocket springs.

Zoned Pressure Relief

We’ve zoned our extra deep visco memory foam layer, varying its levels of density to deliver targeted, precise support and comfort to the different areas of the body. This helps with relieving pressure point build up occurring around the more bony areas whilst not having to compromise on back support.

Open-Cell Visco Memory Foam

Our unique open-cell visco memory foam provides advanced temperature regulation without the use of cooling chemicals. 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.

15-Year Trust: REM-Fit's Durability Promise

At REM-Fit, durability is key.

We rigorously test our mattresses using the Juggernaut machine, which simulates 15 years of use, ensuring they meet our high standards of durability.

Watch the video to see our process in action and discover how our products stand the test of time.

Good Housekeeping Institute, 2024

“Very comfortable to sleep on!”. “The edges did not sag at all, and it has been great for limiting the impact of movement.”

Why are REM-Fit springs superior to your counterparts?

Unlike our counterparts we use tall pocket springs constructed from triple tempered steel. Each spring is contained within its 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 (only) provide superior support and will isolate partner disturbance movement more effectively. 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!
