Combines the Soft Cushion of Polyfoam with the Firm "no bottoming" Trait of Polyethylene. Perfect for young tumblers in their beginner or intermediate stages. The Expando Nova Duo Mat offers a 1" layer of polyfoam which provides the softness for younger, lightweight children, while a firmer 1 3/8" polyethylene layer keeps the mat from "bottoming out" during more extensive use. Nylon reinforced tough 18 oz. vinyl cover uses double reinforced, nylon stitched inverted seams to create a smooth working surface. Each mat has 2" panels and 2" folds and are lightweight for easy handling and storage. Available colors: Red and Royal Blue .
