Abstract
A playground apparatus is disclosed which includes four upright posts secured in the ground in a square configuration. Playground apparatus further includes four curved beam members formed from substantially rigid material, each of which is pivotally connected at its midpoint. The adjacent ends of the beams are interconnected by a resilient spring assembly, and the assembled beams define a ring-like support surface upon which children can stand and jump, producing undulating and resilient motion.
