Surprisingly really like this mattress. When I opened it I left it out for a couple of days until I could get my old mattress out. It expanded instantly after cutting the vacuum sealed plastic. The height of the mattress is great, better than my old mattress. There was no smell at all with this mattress. I was worried it would be too soft but it is not too soft and not too firm. For the price I think this is a great mattress. Glad I got it.
