Five configurations come out of four wooden parts: a 23.5 inch cube, a large triangle at 31.5 by 23.5 by 27.5 inches, a small triangle at 20 by 23.5 by 17.5 inches, and a 43.5 by 18.5 inch board. Stand them separately for a beginner and a one year old has a low frame to pull up on; nest and combine them and the same pieces become a climbing course with height, angles, and a route through. The board is the piece doing double duty. One face is a smooth slide; flip it over and the other face carries rungs for climbing, so a single board covers both directions of travel and there is no second accessory to store. Hooked onto the large triangle it runs steep, onto the small triangle it runs gentle, which is how the difficulty gets tuned to the child rather than the other way round. The cube is open on its sides, giving a tunnel to crawl through and holes to climb between, and the triangle-and-cube geometry is what makes the whole thing stable: a triangle cannot rack, so nothing wobbles when a child leans on the top rail. Each part is rated to carry 132 lbs, well past what a toddler weighs, which means an adult can steady themselves on it during the learning stage. Materials are birch and beech wood with New Zealand pipe rods 22.5 inches long, finished Natural. The set weighs 63.5 pounds, suits children over 1 year old learning to walk and climb, and comes with a user manual.
