Why Choose The 400 Elite Mattress?

3000 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 Elite mattress uses 3000 premium pocket springs, 15.5cm tall.

Weightless Pressure Relief


Our REMCell foam cradles your body, offering a plush layer above our resilient pocket spring system. Paired with our stretchy, hypoallergenic mattress cover, it creates a sensation akin to floating.

REMCell Breathable Foam


Our breathable REMCell foam provides temperature regulation and won't heat up like traditional 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.

Tired of Sleeping Hot?

REMCell foam is designed with innovative open cell technology, ensuring you stay cool by efficiently dispersing heat away from your body for an ideal sleeping temperature.

Good Housekeeping Institute

Soft, super comfortable and provides just the right support! Our GHI testers loved the REMFit 400 Hybrid Mattress and highly recommend for anyone looking for a good night’s sleep!
