Why Choose The 600 Lux?
3500 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 & sumptuous support the 600 Lux combines 2500 mini pocket springs with 1000 tall premium pocket springs, 15cm high.
Zoned Pressure Relief
We’ve zoned our 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 Memory Foam
Our unique open cell 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.
Good Housekeeping Institute
"Being a slightly softer mattress, testers enjoyed the cloud-like and luxurious experience of sleeping on the REM-Fit 600 Lux. It enabled an undisturbed night’s sleep with the layers effectively moulding and supporting testers."
Good Homes Magazine
"This mattress cradles the weight of the body, providing a soft and sumptuous feel, whilst still delivering great support without the without that weird sinking feeling you can get with some memory foam mattresses."

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!
3500 premium pocket springs
2500 mini pocket springs combined with 1000 tall encapsulated pocket springs provide a luxurious and cushioned sleeping experience. The two spring systems work together to produce a uniquely supportive and sumptuous tension. Sleep in peace 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 also help lengthen 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 600 Lux is classified as a soft-medium tension and is ideal for side sleeping or for those who like a particularly luxurious and sumptuous mattress. If your current mattress is causing you to wake with sore shoulders, hips or knees then the 600 Lux might just be the perfect mattress for you!
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 the 'next day' is not 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 (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.
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. 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.
