Designed for safe, creative play, this foam climbing block set uses high-density Epe foam for cloud-like comfort and firm support. The 7-piece layout encourages endless builds-from tunnels and stepping paths to a slide-and-cube combo and a reversible tunnel that can double as a recliner. Rounded edges and hidden zippers add kid-friendly safety, and the removable waterproof Pu leather cover wipes clean fast. A great activity set for toddlers ages 1+ to develop balance, coordination, and gross motor skills.
