I am kicking myself for purchasing these at $** for three! They're an inch thick at the tips of the contours, more like 1/2 an inch at the valleys, so to get a really soft feel I have to use two or three. I'm also disappointed by the quality of the foam, it seems lacking in density. Definitely keep shopping!
Holder is very attractive. Arms move around the holder easily. Didn't come with instructions to put together but it was easy to figure it out. Very heavy and solid. Easy to move around when needed. Very pleased.
I cover every mattress in the house. This pad is the best because the vinyl inside is laminated which means it holds up but also stays silent. I have one under our padding on our kind size bed and bought this for my teen. The multi-pack is great if you have several kids and for home and college dorm beds if they have regular size twin beds. I think it's available in extra-long twin as well.
