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?
