Why Choose The 500 Ortho?

Tall Pocket Springs

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.

Cool-Gel Infused Foam

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.

How firm is the mattress?

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

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 'next day' isn't 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 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 the 500-Ortho model 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, 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.
