Before this mattress topper, my daughter tossed and turned and seemed to have trouble getting comfortable. The twin spring mattress she sleeps on is not new, but still has plenty of life in it. So I considered the mattress topper as a temporary solution until we could afford a better mattress. Such a wonderful investment! My daughter is finally comfortable and does not toss and turn nearly as much. She says it might be too soft, as she does sink down into it, but I think that is the reason it is easier for her to fall asleep and stay asleep without tossing and turning to get comfortable. This is an item we will happily have and enjoy for a very long time!
