After reading the other reviews I had a hard time deciding whether to get the firm, med, or soft. I went with the soft which is still firm enough. It is very comfy. I didn't notice the smell as being horrible. Make sure you open the mattress close to where you're going to put it because it expands very quickly. I love it so far. I have a two inch featherbed on top only because I already had one. You probably don 't need it. Sheets are a little hard to fit. Buy the deepest ones you can find. The 18 inch aren't big enough.
