Progression Interlocking Judo Mats The interlocking foam mats are built with a high-density, high-quality EVA foam that allows for optimal padding and shock absorption. The anti-slip and easy-to-clean surface is ideal for kids play rooms, bunkhouses or for your exercise area. The interlocking system has a unique puzzle piece design which allows it to fit tightly against other mats, keeping a tight seal and not allowing dirt or other particles to get inside the cracks. *Sold as 1 mat with two edge pieces* *Available in Green/Black or Red/Black* Specifications SKU: EXAPROJUDOMATBG - Progression Interlocking Judo Mats Black/Green EXAPROJUDOMATRB - Progression Interlocking Judo Mats Red/Black Dimensions 1 mat dimensions 40" (L) x 40" (W) x 0.75" (H) / 101.6 x 101.6 x 1.90 cm 4 mat dimensions with edges 81" x 81" x 0.75" / 205.74 x 205.74 x 1.9 cm
