Why Choose The 600 Lux?

Tall Pocket Springs

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.

Weightless Pressure Relief

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.

Cool-Gel Infused Foam

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.

Sleep on it, jump on it and everything in between - it's yours for 100 nights to fall in love with. If it's not right for you, we'll collect for free and refund you in full.

Free next working day delivery when you order before 1pm & free day of choice delivery. Old mattress disposal can be selected at the checkout.

How firm is the 600 Lux mattress?

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!

How does the 100-night trial work?

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

How long does delivery take?

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.

Why are REM-Fit springs superior to your counterparts?

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.

What base can the mattress go on?

Thanks to the high-density foam layer of the mattress you can confidently use the mattress on any bed base including adjustable beds!

I have a bad back - will this mattress help?

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.
