I bought this for my guest bedroom.   My brother has recently moved in with us and is sleeping on that bed.  I knew it was a bit firm and he that he is used to a softer mattress so I wanted to get him a topper.   He could not believe how much a difference the topper made!  He said it made the bed so much more comfortable.  We did have a bit of trouble getting it on exactly like I wanted.  It hasnt moved a bit since we got it placed.  It fits the bed prefectly.
