I can't believe the improvement in my sleep with this foam topper!  It's so soft yet it isn't so soft it makes it hard to move during the night. I don't have any hip or shoulder pain from staying in one position too long and my regular sheets still fit with it.  I let it air out for 48 hours before putting in on my bed but never noticed any new foam smell even from the beginning. I wish I would have bought it sooner!
