After seeing these on a shopping channel was sceptical, but urgently needed a new mattress. It was quite heavy to handle and came rolled up. The first thing I did after unrolling the mattress was put a glass of water in the middle of it, like they demonstrate on the tv, sat down on the bed and the glass of water didn't flinch. Very odd feeling sitting on it for the first time, it doesn't move and seems quite hard. I suffer with sciatica and a dodgy shoulder and can honestly say that this mattress appears to have helped; no aches when I wake up. There's no roll-together either (if that's what you're after). so it's great if one person is twice as heavy as the other! One thing I hate with traditional mattresses are the little buttons that fix the quilting, I don't know about you but I can always feel them, most uncomfortable. However, with the Dormeo Fresh Plus mattress theres none of that. At the price it's wonderfully comfy and I wish I'd bought one sooner. Try it.
