Originally designed by NASA, Memory foam moulds to your body, giving orthopaedic support and superb comfort. It also helps to overcome the pressure points of the body.
The Reflex foam in this mattress will give you excellent orthopaedic support but also excellent comfort with its memory ability.
This mattress is approximately 20cm deep.
Slightly firmer support than a typical medium feel mattress.
To aid with hygiene, this product has a zipped cover that can be removed for washing.
The Coolmax cover helps to remove moisture from the sleeper, giving a cooling effect. This also keeps the mattress dry, fresh and hygienic.
If you require extra support for your back and shoulders, this firmer orthopaedic mattress provides it perfectly.
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully and are usually ready to sleep on within 48 hours.
Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.
Being hypoallergenic and dust mite resistant, this is the perfect item for asthma and allergy sufferers - or anyone looking for a healthier night's sleep.

Very good mattress. Comfortable
Really comfortable
The mattress itself is very good although it is slightly wider than advertised and doesn't sit in the studybed frame very well.
Very happy with my purchase. Does what it say.
Great mattress as described on the website. I would recommend it. Good value for money and good service.
Very comfortable mattress, a lot cooler than my old one. So getting better night's sleep
After using one of these mattresses whilst visiting my daughter I was very happy to buy one for myself. I can say that menopausal nights are not worsened by the foam, as I had feared, which provides a good support for the body and helps with getting some real sleep!
The mattresses I purchased (double) are comfortable but 2 weeks on, the smell remains. I had read a review warning this problem so was prepared and have left bedroom doors open so hoping the smell fades soon.
Excellent and very comfortable.
It's ok very firm if I could exchange it I would
Only had for few days seems fine
This mattress is firmer than I am used to but my back has been less painful since using it.
it is great value for money.
Very comfortable mattress give my back plenty of support
Really comfortable and a great price. Very happy.
Purchased for my son who said it is so comfortable it's the mattress' fault he doesn't wake up. I've tried it out and will be getting myself one when I replace mine. We had not used a memory foam before but this was outstandingly comfortable. Gives good support.
Really comfy and good quality
I was a little concerned about buying a mattress over the internet, and also on how good the quality would be for a memory foam mattress considering the price. But it's exceptional! The delivery was quick and the man helpful in recycling my old mattress, and i'm now sleeping deeper than I have in years!
Excellent service & product
Good value, firm, what I ordered.
Very comfortable. Would recommend
It's very firm (as I wanted) looks good, well made etc. Have had no trouble sleeping on it, so result!
The product is ok but the delivery was horrible. I bought two mattress and the man who came just left them in the entrance. I asked very politely for some help because I live in a third floor without lift and he told that he was very busy. I'm really disappointed with that and I don't think i'll recommend the company to anyone.
Most probably the best mattress you can buy for the money, really really comfortable, we love it!
