Our Folding Mats are the perfect discount mats for anything from gymnastics to martial arts. These mats feature a V4 system, which means Velcro has been attached to all sides of the mat. This allows you to connect many folding mats together to create a flooring surface or you can use these mats as wall padding. Our folding mats are covered with an 18oz. casing surrounding a thick 2" foam core, and come in popular colors.
