This mat is safe, durable, and easy to store. Inside double-stitched seams prevent sharp edges and provide higher durability than “heat-sealed” or “radio frequency sealed” seams, and they give children no outside binding to pick at or tear loose. Name tags are sewn on the end of every mat to stop fighting, confusion, or health risks. The mats are made from high density D31 foam and durable blue vinyl. These mats resist moisture and wipe clean with a damp cloth. They are easily sanitised with bleach and water. All mats are proudly made 100% in the USA.
