Triple Layer Hybrid Fitness Mats

* the center lay (with the thick, soft, 2# crushable foam) has the ability to crush and bounce back, giving it a comfortable feel without eventually losing resilience and thickness * the outer layer has a thinner density, 6# polyethylene foam to allow the softer foam in the center to be more easily felt, yet the higher density & non-cross-link nature gives it a tougher, more abrasion resistant surface * warranty: 3 years
