Three interconnected foam pieces create a climb and crawl layout that lets kids ages 1 and up move, sit, and explore around a soft ball pit. The 40 x 40 x 10 in pit pairs with 20 x 20 x 10 in triangle and stair blocks so children can climb in and out on low, cushioned surfaces. High-density EPE foam helps the shapes keep their form while the PU cover wipes clean after play. Hook and loop fasteners keep pieces aligned, and 100 ocean spheres fill the pit for active, hands-on fun.
