The first puzzle mat was a gift, and was so well received that we have now ordered a second. The insulation against the cold / cold floor is super. The puzzle mat exudes does _not_ chemical smell, so we have no fear when parts are taken once in the mouth (which can hardly avoid). The puzzle mat is thrilled apart reassembled "torn" and elsewhere, that is in itself a great toy, although it should serve only as an underlay. Highly recommended.
