PLEASE NOTE THIS ITEM CANNOT SHIP VIA 3 DAY DELIVERY. This is the strongest carpet used anywhere in the gymnastics industry, yet it is soft, with the touch of velour. Each roll is lightweight and designed for performance and easy set up and storage. Manufactured with closed cell, cross linked polyethylene foam, renowned for its shock absorption and resiliency that gymnasts and cheerleaders demand of their training and competition floors. Our foam layers are heat laminated to our famous needle punch carpet for outstanding durability and non slip traction. The bond between the carpet and foam is critical. During manufacturing, the foam becomes liquefied. In the cooling process, the carpet and foam substrates actually become one piece, creating a permanent, virtually indestructible bond. The floor consists of 7 rolls 6' x 42' x 1 38' which combine to create a 42' square surface. Purchase all 7 rolls together or buy them individually as your budget allows to build an entire floor
