1 Disappointing Posted by Marny Pigott on 11th Nov 2018 I bought this in July. It looked like the stones were on mesh but they are stuck to very thick felt probably about 1.25 inches. The felt sucks up lots of water and inevitably stones fall off: a dozen or so have come away already. When soaked the mat is heavy and difficult to manage so drying it out is difficult and takes ages. A complete waste of money.
