I previously bought a Hypnia pocket sprung latex mattress about 7 years ago which was hands down the best mattress I ever had. I bought another pocket sprung latex mattress from Hypnia recently which I believed would have been very similar to the previous one but it is not. The old one was medium firm, this one is medium and a little softer than my old one, the old one had a latex topper on both sides of the mattress so was turnable, this one is one sided so can't be turned, and I believe it is synthetic as opposed to natural latex like the old one was. I also find this mattress warmer than the other one (probably because it is a different type of latex) and have woken up hot and sweaty on a number of occasions in November - I didn't have this problem with the previous Hypnia mattress. All in all I am dissapointed as the last one was a truly fantastic mattress but sadly I can't say the same about this one. It is okay and not a bad mattress for the money, just that the old one spoilt me as that was a fantastic mattress and I feel that Hypnia like a lot of companies have done some cost cutting to their product as the quality and comfort of the previous mattress was better in my opinion.
