Abstract
A unique climbing structure that is durable, lightweight and easy to assemble is provided. The structure is based on the use of polystyrene foam blocks attached to a support structure. The polystyrene can be cut to be irregularly shaped like a normal rock, and can be shaped with larger dimensions and depth than other techniques, giving a more realistic structure. The shaped polystyrene foam is covered with a hard coating to give the exterior a rock-like appearance.
