Pre-walking enrichment, soft enough for first tumbles. This 4-piece climb-and-crawl foam set pieces together into a configurable obstacle course of bumps, ramps, and wedges for crawlers and new movers. High-density foam holds its shape under repeated climb attempts while a wipe-clean vinyl cover handles snack spills and drool with a damp cloth. A go-to for living-room play sessions and screen-free morning routines.
