Three components - a 27 in climbing triangle, a 34 in arch and a 31.5 in balance bridge - combine or separate into eight configurations, so the set grows with a child from crawling at one year to climbing at four. Each part carries 110 lbs and the set 330 lbs together, enough for an adult to steady a toddler. It folds to 34 x 19 x 31.5 in for storage behind a door. Birch, beech and engineered wood in macaron pastels weigh 26 lbs, with a cushion included. Assembly is required.
