Designed specifically for children’s sensory and physical development, this 4-tier soft vaulting box features a modular design that allows for flexible height adjustment from a single layer up to four tiers. The core is made of high-density PU foam, providing excellent shock absorption and support, while the exterior is wrapped in eco-friendly, wear-resistant PVC leather that is easy to clean. All edges are rounded and burr-free, significantly reducing the risk of bumps and scrapes during climbing or jumping. It is a core piece of equipment for gymnastics and sensory integration programs, helping to improve children’s coordination, explosive power, and spatial awareness.
