    This product contains Geltex - an all new comfort layer that offers you the ultimate in comfort and support. Geltex delivers triple benefits to offer the perfect sleep solution: incredible body support, ideal pressure relief and unrivalled breathability.

    Memory Foam

    Memory Foam

    Memory foam responds to body heat by softening and matching the shape of your body, allowing superb orthopaedic support and incredible comfort. Originally designed by NASA, the memory foam (also known as Visco Elastic) disperses your weight throughout the mattress, alleviating pressure points and allowing freer blood circulation - resulting in an excellently restful night's sleep.

    Knitted Cover

    Knitted Cover

    The mattress is covered in a luxuriously soft knitted cover with the added benefit of being breathable.



    This mattress is hypoallergenic & resistant to dust mites, is ideal for asthma and allergy sufferers, or anyone looking for a healthier night's rest

    Pressure Relief

    Pressure Relief

    Provides maximal pressure relief, by spreading more of your body's weight across the mattress - less toss and turning, more restful sleep.

    Medium to Firm

    Medium to Firm

    A firmer level of support than a medium feel mattress.



    Mattress depth 27cm (10.6") approximately.

    No Need To Turn

    No Need To Turn

    This mattress is purposely designed to be single sided for your convenience - there's no need to flip it over, but we do recommend that you rotate the mattress regularly.



    Made from materials that are 100% free from animal by-products.

Maidenhead GB
Always bought pocket spring until choosing this mattress. Hasn’t disappointed yet. Please note that for some people it does take a little time for the back to adjust.
I didn’t buy it sooner.

Bristol GB Now loving sleep!
I had thought that I didn't get bed sores. I had thought that they only happened to other people. That is until I bought this mattress. It was odd. I got out of bed in the morning (very hard to do with this mattress) and then realised that my body didn't feel like it had been lying on a bed all night (such was it's excellent support). At that point it dawned on me that my previous mattress was making me sore, it's just that I had got used to it! It was only the absence of this soreness brought upon by this mattress that had highlighted the problem.

I was going to go for the Studio mattress, but this one seems better specified, hence why I went for it.

It's my first memory foam mattress and unlike other people, I got used to it right away. The comfort levels are such that I will never go back to a sprung mattress.

I had thought that the medium firm would be too hard. But it's just right. It's soft enough to be extremely comfortable, but also hard enough to support my weight properly (I weight around 75kg).

Highly recommended. Should have bought one of these a long time ago!
It smells a bit when you first get it. For me, it took around 2-3 days to clear.

Like sleeping on clouds
The strong chemical smell that lasted for first few days as with mild weather we could leave several windows open all day which helped get rid of smell quicker. but if winter months could take a week or so to get rid of smell?
