I bought this topper after we won a new bed from a local furniture store. It was more firm than any bed I'd had before but we thought that's what we wanted. After two or three nights I was sleeping horribly and thought about just trying to return the bed but then found this product at such a decent price, we decided to try it and salvage our "free" bed. WOW! I was hesitant because of the reviews but it has given me the most amazing nights of sleep I've ever had. You can smell the smell everyone's talking about, we let it air out for one day but once it was under a fitted sheet it hasn't been an issue. This topper makes your bed very soft. I'm a side sleeper so this is what works for me, if you are looking for more firm, this isn't the topper for you. Also it is not hard to move out of one position and it doesn't take too long to reform - some things I was worried about. I typically sleep hot but haven't had issues with temperature either. I would highly recommend this product to anyone looking for a good nights sleep!
