Four foam shapes connect into a low climb and crawl course so infants can move over cushioned obstacles. The set includes a rectangle, a slide, a step and a thin sector, each with an 18-in square footprint to create a consistent landing area as children shift from piece to piece. EPE foam filling helps absorb impact under knees and hands, while the PU surface wipes clean. A hook-and-loop system keeps the pieces aligned, and zippered covers remove for easier maintenance.
