Is it made of floor or foam?
Mats should be made of foam mats, not made of paper. Foam pad plays a role of sound insulation and buffering; in order to prevent moisture, the ground cushion should be covered with plastic cloth; this kind of geothermal can be emitted, do not worry
Puzzle Foam floor, floor leather, I still recommend the latter, because the former is a spell of more thin seam, so it is not conducive to good health
