Sleeping on this mattress topper is like sleeping on a cloud!  It’s so soft!  I have a twelve inch mattress and a fourteen inch box frame, so when I added the four inch topper onto my mattress, I feel like I need a ladder to get into bed, but it’s so worth it.  This is the best sleep I’ve had in years!  Other mattress toppers have slipped around the bed, but not this one.  The mattress pad cover included really helps keep it in place.  There was a slight odor the first night or two, but it went away pretty quick.
