Why Choose The 500 Ortho?
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 500 Ortho mattress uses 2000 firm, premium pocket springs, 15cm tall.
Zoned Pressure Relief
We’ve zoned the memory foam layer in the 500 Ortho, 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 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
Re-Ax® Breathable Cover
Encasing the 25cm deep Hybrid mattress is our exclusive thermo-regulating Re-Ax knitted fibre, providing a fully breathable fabric structure that is silky soft to touch. The cover is removable and machine washable too.
Zoned Support
Zoned comfort areas provide added cushioning which reduces pressure from building up around the bonier areas of the body, giving a feeling of floating and universal comfort, say goodnight to sore shoulders, hips and knees.
Cool open-cell memory foam
Heavenly comfortable and unlike standard memory foam mattresses it won't leave you hot and sweaty. We've developed a unique layer of body moulding and temperature regulating memory which won't heat you up!
2000 firm pocket springs
2000, 14cm tall extra firm encapsulated pocket springs provide excellent back support and comfort. Each spring moves independently, supporting and responding to your different sleeping positions, whilst allowing a peaceful night's rest without being disturbed by your partner's movements.
Edge-to-edge support
Foam encapsulated side walls deliver strong edge-to-edge support allowing you to sit or sleep tight to the edge without the risk of 'roll-off'. The edge walls will ensure a consistent tension is kept across the entire surface of the mattress and will help extend the life of the mattress.
Strong foundations
A deep layer or high-density foam sits at the base of the mattress, providing a robust and extremely strong foundation, enabling the mattress to comfortably withstand a total combined weight of up to 40 stone (20 stone per sleeper max) for a minimum of 15 years

The REM-Fit 500 Ortho is classified as a firm tension. If your preference is a supportive mattress or you suffer from a back complaint, the 500 Ortho is our recommended choice
We provide a risk-free sleep trial on all our mattresses. This allows you to sleep on a REM-Fit for 100-nights in the comfort of your own home and really put it to the test! There are no catches. If the mattress, for whatever reason doesn’t live up to your expectations, you can send it back for a full refund. There are no collection charges either! View more info here.
We can deliver your new mattress the very next working day providing you place your order by 1pm. You can select a chosen day for delivery if 'next day' isn't suitable. We have a suit of delivery options to choose from when 'checking out' including weekend and guaranteed AM slots.
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 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.
Thanks to the high-density foam layer of the mattress you can confidently use the mattress on any bed base including adjustable beds!
As non-medical professionals we make no guarantees that the mattress will improve your back complaint. However, we have designed our mattress range with a focus on back support, the 500 Ortho being our recommended mattress for back sufferers. We have also received lots of positive feedback from sleepers who have suffered with a bad back to discover that sleeping on a REM-fit has relieved their pain and enabled them to get a great night's rest.
