Designed specifically for sensory balance training, this soft rainbow arch bridge features an eco-friendly, odorless high-density PU foam core. The exterior is covered in thickened, non-slip PVC leather with a textured surface to prevent slipping. The arched design simulates uneven terrain, challenging children to maintain balance while walking over or crawling under it. As a modular piece, it can be combined with barrels and vaulting boxes to create engaging and complex obstacle courses for active play.
