I ordered this mattress as a replacement for our queen that was destroyed in a flood. It came very quickly, was a great price and light enough for me and my friend (2 slight women) to carry out of and into a house. I left it unwrapped in the bedroom and it was it's full size in 2 days, a light odor lasted for a week but it was not unpleasant or overwhelming. It has been 9 months and I love this mattress. We ordered the King because we wanted space and room for the dogs/cats and children. It is soooo comfortable, I feel nothing when multiple bodies are jumping and tumbling on the bed and my back feels great. I recommend this mattress highly, it has met all my expectations.
