Why are Rejuvenated mattresses so cheap?

The rejuvenated mattress range are from our award-winning sleep range which have been returned during their 100-night trial period.

Every returned mattress is inspected for damage and faults and any returned mattresses deemed faulty or damaged are sent to a recycling centre.

Mattresses returned in excellent condition are steam cleaned, maintained and if required fitted with a brand-new REM-Fit mattress cover. The mattress is then rolled and boxed ready for next day delivery.

Why Choose The 400 Mattress?

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.
