Review (2/5): Maybe it's helpful for warmth, but not for padding
I returned this because it made no discernible difference in the comfort of my massage table. I had it out and back into the package in under a minute. Under a flat sheet there's no way anyone could tell there was any additional padding. Maybe it'll reflect back the client's own body heat, but table warmers are better for that, and a layer of foam padding would be a better purchase than this.
