I've been suffering with a bad back for a few years now, I thought it might be the mattress so I spent £1800 on a new one from a big brand name, my issues continued and I just accepted it as part of getting old. We bought this mattress for our spare room and one night when I was restless and didn't want to wake my wife I decided to sleep in the spare room, the next morning my back pain eased, I used this mattress for another couple of nights and my aches had virtually gone. I couldn't believe it what an amazing product. I then started using the main mattress again and after a few nights my back pain returned, one night on the Aspire mattress and I woke up pain free again. I have since bought another one for the main bedroom and have been back pain free since. The two Aspire mattresses cost about the same as the one big brand mattress, fantastic quality and value literally changed my life. Thank you Aspire.
