I purchased a new bed and it was a little firmer than I liked. I was looking at foam toppers and didn't want to spend a fortune since I just bought the bed. This was exactly what I needed. It fits to the edges of the mattress which I was concerned about based on the picture! It does have that foamy smell when I first opened it which it suggests to not cover for 24 hours so I did and didn't notice anything after it was on my mattress. It adds just enough comfort and softness to my firm mattress!
