Fabulous, wonderful, and I didn't experience any weird smells. It is so comfortable, I have a foam mattress under it from Overstock as well that is firmer and not as thick as advertised but this topper more than makes up for it. Yes it could rip, be careful, it is hot so I plan to put a really thick mattress cover on it, but the comfort! No more inner spring mattress for me ever! I have had it for months and it looks and feels brand new. Excellent quality.
