This is the first time I bought a memory foam mattress and from online. I never slept on one before. i really just took the risk and went with the reviews on this website. Well, I have to say it's very comfy. I put a topper on and it's been a great bed for me. I do prefer a hard/firm bed and this one is not VERY hard but it's very comfortable. I've been using it only for less than a week. I will update more if it changes. The smell was there only for a few days at most.
