I have had my bed for about a month now. It came rolled up and took about a full day to expand. It never reached its whole 10"..its only 9" but thats ok. My regular queen size sheets do not fit over it, which is weird because its not much bigger than my last mattress. I only noticed a slight smell the first day. I ordered the soft support and I'm so glad I did. It is still very firm. It took about a week to get used to sleeping on it, now I love it. It is so comfortable. I have a lot less back ache, and don't wake up during the night nearly as much. Overall its a good bed. Can't beat the price.
