I can't really review how this cushion functions because I can't get past the horrible PVC smell. It's incredibly strong. I put a bathroom mat on top of the cushion to try to cut down on the smell, and also because the smell was transferring to the seat of my pants so that I could still smell the cushion even when I wasn't near it! I was, in essence, wearing the cushion! I might give this cushion away. Hopefully the company will come up with a better, less toxic and less toxic-smelling material to make this from. I think the cushion is a good idea, and if it's supposed to be health-promoting, it should be healthy for us in *all* aspects, including the material it's made from.Product Description
