Product Details

The REM-Fit 600 Lux is classified as a Medium-firm 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!

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.

We provide a risk-free sleep trial on all our mattresses. This allows you to sleep on a REM-Fit for up to 200-nights, in the comfort of your own home, and really put it to the test!

If the mattress, for whatever reason doesn't live up to your expectations, you can send it back for a full refund without collection charges!

We request that you give your new REM-Fit mattress 30 nights to bed-in before you raise a return. This will give your body the right amount of time to fully adjust.

Experience swift and seamless service with our *free 1-3 day delivery to UK addresses! Our dedicated 2-person team ensures your new mattress is delivered right to your room of choice.

Enhance your convenience further by opting for old mattress removal at checkout for a nominal fee.

Enjoy complete flexibility with delivery dates: Our courier will contact you via email and WhatsApp, providing a selection of dates to choose from. The day before delivery, you'll receive a precise 3-hour time window. Plus, our drivers will give you a call when they're just 30 minutes away - Your comfort is our priority!

We’re confident in our mattress quality, so every new REM-Fit mattress comes with a 15-year guarantee (1 year for rejuvenated models) at no extra cost.

Just set it up on a supportive base, and you’re covered! In case of a replacement, your original guarantee period remains, and if it’s an upgrade, simply pay the difference. Note: returns must be unstained and claimed by the original buyer only.

Remember to register your guarantee. Full T&C's on our guarantee are covered in our general T&C's page.

Financing your new mattress is easy with flexible options at the checkout! With DivideBuy, you can spread payments over 12 months interest free - simply apply at the checkout for an instant decision.

Prefer a shorter term? Choose PayPal or Klarna to pay over 3 months interest free with zero hassle.

If you decide to return your mattress during the sleep trial, no worries - any payments made will be refunded, and your finance agreement will be cancelled.

Heaven (600 Lux Elite)

So, I ordered the wrong size mattress and they sorted it before delivery and were fantastic. The delivery was smooth and the delivery guys were absolutely lovely.The mattress itself is just amazing. I am a terrible insomniac and this mattress (i ordered the medium firmness) has genuinely improved the amount of sleep I get and most definitely the quality of that sleep. £600 seems like a lot of money but it is absolutely money well spent as sleep is so important. Absolutely fantastic purchase! So, I ordered the wrong size mattress and they sorted it before delivery and were fantastic.

400 Elite Mattress

I've been sleeping on the 400 Elite mattress for over 6 months now and can only sing its praises. For me, pressure point relief is a must as I predominantly sleep on my side - this mattress performs perfectly for me and still feels supportive despite it's soft sleeping surface.

Good supported pillows

Bought 2 pillows, one for me (400 Memory Foam) and one for husband (500 Cool Gel) and have been happy with our purchase. I have noticed my neck is supported better and less headaches in the morning. Got the discount for buying 2 and the Over 50's which helped with the price. Bought 2 pillows, one for me (400 Memory Foam) and one for husband (500 Cool Gel) and have been happy with our purchase.

Thanks for the great customer service

Bought a mattress from Rem-fit and it arrived on time. After sleeping for a few nights we realized that it was too soft for us and that we prefer something firmer.

The quality is excellent (Pocket 1000)

Very happy with the REM-Fit 600® Lux Elite Hybrid Mattress and service from start to finish. Mattress was delivered directly to the room and the old mattress removed without fuss.
