    Mattress is a little more firm than we expected, but nice quality. Our chief concern was that 1/3 of the surface of the mattress arrived discolored in a light brown color. Overstock customer service was great and immediately issued a new replacement.

    Excellent mattresses - we sleep like babies on them now - no back pain in the morning anymore. Just enough support and firmness - medium to soft I would rate them, but like I said: No backpain anymore - really rested in the morning!

    Love this mattress, super great value as well. Slept on it a few nights already, but seems wonderful, a bit firm but I like that. I let the mattress set for a few days on the bed before making the bed, the smell goes away after the first couple of days. Love the fact that is is reversible.

    We received our mattress 2 weeks ago. It came in a 90lb package - my poor UPS guy. It came in the middle of the week and we did not get in in place in our bedroom and open it until Saturday. It expanded rapidly and felt wonderful laying on it. We got the medium firm mattress. We were so excited to sleep on it as we have been suffering on a 13 year old, worn out major name brand memory foam mattress. Here's the bad part - The smell of it was just awful. I mean get sick to your stomach awful. I knew we needed to wait for the off gassing to take place. So we waited 2 days as recommended. We tried to sleep on it 3 days later and after about an hour, my eyes were burning and I was feeling queasy. My partner was also feeling sick. We had to sleep in our guest bedroom that night and we are STILL there. It's been 2 weeks and the smell is still bad. I have tried opening the window with a fan pulling the air out the window and the smell is still there. I haven't given up yet, but ...
