Our Rebound Mat is designed for extra lift and rebound since we have added a layer of EVA foam on top of rebound foam * These red vinyl mats are great for high-end tumbling and cheer stunting and have Velcro on all four sides * Rebound Mats have non-skid material on the bottom to prevent moving and sliding * It is the ultimate tumbling mat because it feels springier than a standard tumbling mat with the special added foam * They do not contain lead and have passed testing requirements enacted by the Consumer Protection Safety Improvement Act of 2008
