Why Choose The 400?
2000 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 the REM-Fit 400 mattress uses 2000 premium pocket springs, 15cm tall.
Weightless Pressure Relief
Memory foam gently absorbs the weight of your body, providing a soft sleeping surface on top of the supportive spring system. Coupled with our hypoallergenic stretched outer fabric the end result is often described as a feeling of weightlessness.
Open Cell Memory Foam
Our unique open cell memory foam provides advanced temperature regulation and won't heat up like standard memory foam. 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.
Why our mattresses are rated so highly
