Six foam pieces cover more play patterns than a single climber: a stair, an arch to crawl under, a slide, a cylinder to roll, a rectangle, and a flat cushion for landing. Children climb, walk, crawl, build, and lie down across the same set, which holds a 3-year-old's attention longer than a fixed-shape toy. Velvet resists pilling and will not hold static charge, so the red surface still looks new after a season in a nursery. Covers unzip for cleaning between groups of children. The set ships compressed, so allow 24 to 48 hours after opening for the foam to reach full height.
