I bought this 2 weeks ago, and have been sleeping on it for about a week and a half. I was surprised right away at how supportive it was. We did not want the taller mattress so we went with this. My husband and I have been having some pains here and there from the old mattress so we knew it was time. I also have been down with a knee injury so I was spending a lot of time laying down. My pelvis was always sore before, and now I wake up feeling really refreshed and my aches are nearly gone. I'm sure after some more time I won't even remember what the old mattress felt like. I highly recommend this mattress. It is exactly as advertised. I was so hesitant because of the price but it seems that capitalism has designed us to think we need to spend thousands on beds to be comfortable and its just not true! Thank you for an honest product. I will be buying again for a guest bed!
