4 section set. These Deluxe foam balance beams are 4" high and 5" wide, which is optimal for developing basic beam balancing competence for grades K to 4. They provide many beam configurations and creative uses beyond balancing. They encourage creativity in the development of set-up patterns and creative challenges. Each beam includes Tube Connectors to attach the beams together in a straight line or right angle configurations. SAFETY: Beams should only be used under qualified adult supervision. Special needs students or those particularly deficient in balance ability may require spotters assisting on each side, and may require extra precautions such as gym mats positioned on each side of the beam. Never run, push, or pull others on the beam.
