The US175555 product complies with the ASTM Standard. The Troll's Trees consist of three upright posts and two bars at different levels. The uprights on the edges have three and two branches respectively. These tree-like elements develop the children's motor and social skills. The trees offer diverse opportunities for play besides hanging and climbing: the children's imaginations will bestow them with diverse forms such as an enchanted forest, a gate or an obstacle course!
