My mattress arrived 4 days after ordering. I ordered the Queen size - medium. Unpacked fairly easily, there is an odor but it doesn't bother me nor is it very strong. I have slept on the mattress for 3 nights so far and it is great. I had been trying to decide between the firm and the medium and I am glad I got the medium. It has a little softness, but it is mostly firm which I like. I am getting used to it though as my old mattress was rather soft. Also, I had lower back pain regularly with my old (granted it was pretty beat-up) mattress. After the 1st night sleeping on this mattress, my back immediately felt much better. It feels a little better every morning too and that is one reason why I am so happy with this purchase. The other reason is because though somewhat firm, this mattress is super comfortable. If I could have tried these out in the store, I am thinking that I may have gone with the plush option. I am very happy with the medium, but I suspect some might consider it to be on the firmer side. Then again, because there is no label (that I could find), perhaps they sent me a firm instead of a medium. I doubt that is the case though.
