Up, down, over around…kids love foam climbing blocks, and they provide a great workout, but wow, are they expensive! So we invented a unique, affordable alternative: the world's first inflatable climbing gym. These heavy-duty, weighted blocks cost a whopping 70% less than similar foam activity sets and require almost no storage space. Includes four block shapes: half-moon, cube, triangle, and crawl-thru tunnel. For ages 12 months and up, to 70 lbs. To build endless obstacle courses, add the Connector Set (sold separately). Inflates in 15 minutes with our Pump (sold separately). Designed by OneStepAhead!For more information, click here.
