Three beech wood pieces combine or separate: a 29.5" climbing triangle with adjustable rung heights, a 35" arch that flips over to become a rocker, and a 38.5" reversible ramp for climbing one way and sliding the other. Used together they form a small obstacle course; used apart they suit different ages in the same household. Each part supports 110 lbs, and the triangular geometry keeps the whole set from shifting during use. Solid beech throughout. For ages 1 and up; total net weight 23 lbs.
