I'm a 67 yrs old women with a artificial hip and very tender pressure points. Love it, quick delivery, no smell, and the double fit great, opened up great after the 48 hours of rest.  I would recommend this mattress topper to anyone who is having trouble sleeping, or one who has trouble with pressure points.  It's so comfortable, I even find it hard to get out of bed some days, and I find myself going to bed even earlier. Just love it.
