Five ways to play out of three beech wood pieces: a climbing triangle with adjustable rung heights, an arch that flips over into a rocker, and a reversible ramp that reads as a climbing ladder on one face and a smooth slide on the other. Each piece stands alone for a new crawler or locks together into a full course once a toddler is steady on both feet. Rung positions on the 29.5-in triangle move up as reach improves. Every part is rated to 110 lb and sanded burr-free, and the 23-lb set meets ASTM and CPSIA requirements.
