This has turned out to be a very good purchase. The mattress inflated to its full size very quickly. It only had a mild chemical smell to it, barely noticeable, and it fully dissipated within a week. The mattress is very comfortable, althouth not as "plush" as I had hoped. I know that memory foam mattresses tend to feel firmer than regular mattresses, so that's why I ordered the "medium-plush" instead of "medium-firm" version. I've gotten used to it, but it took me a few days. I'm very happy with my purchase and would buy it again.
