I love this topper! I ordered a King even though I have a Queen. I cut it down to size so it would fit perfect on my mattress (careful, not that easy to cut down!). Yes, it does smell but not that bad and I have a sensitive nose! I let it air out for a day and a half and I was fine to sleep on it last night. I also put the mattress pad I ordered as well over it and it worked out great. Two thumbs up! I would suggest everyone have one of these on their bed!
