The first night I slept on the memory foam topper it was a bit too soft. I would like for it to have a little more firmness to it. However the second night it was better and the third night was even greater. I had to get use to the softness after sleeping on a very firm mattress for years. There was a very slight smell that did not last long. I must admit I do not feel any stiffness in my body anymore (back, neck, shoulders, arms, right and left side). Glad I made this choice.
