The beam is filled with dense, extra-firm Epe foam that resists compression and maintains its shape over time, offering reliable support for users ranging from young children to adults. The top is covered with a comfortable, non-slip Pvc surface. This crucial feature helps prevent feet from slipping during maneuvers and provides a slight cushion to soften landings, making it ideal for practicing foundational skills like walks, jumps, cartwheels, and handsprings with greater confidence.
