Hi there. I came across your website by accident and really like the way that you really try and help customers with straightforward advice. I'd like to buy a new mattress but I'd like a bit of advice about construction. Over the past six years I've bought two new mattresses - both seemed very good when new but after about a year they were less good. The first was a John Lewis mattress with a two inch layer of memory foam - felt great initially but very soon it became obvious that the insulating effect of the memory foam was causing a problem. I radiate quite a lot of heat while sleeping (according to my wife) and the memory foam just made this worse. I used to waken up in the middle of the night soaking wet and it was horrible. Eventually I resorted to sleeping on top of a large cotton towel but this was pretty unsatisfactory. So we threw out the memory foam topped mattress and following a recommendation from a local furniture shop we bought a 'Bamboo' mattress which was supposed to help keep you cool. It did do that and the overheating problem stopped but the mattress itself didn't seem to be great quality and despite being turned very month it became very lumpy and uncomfortable. I've spent a few nights in Premier Inns and the mattress there was very comfy but I have concerns about the quality of the Syphos mattress (which I think is the one they use). I'm very keen on your Origins Pocket 1500 - do you think that would be suitable bearing in mind the problems I've had with my last two mattresses ?
