The US175535 product complies with the ASTM Standard. The Goblin's Track is a balancing track set at a height of 1.8 ft, consisting of 12 beams. It can fit several children at a time. Traversing the track develops the children's sense of balance and motor skills. The shape of the track fuels the kids' imaginations, turning it into a wide variety of things: horse pens, garages, rows of houses... Older kids may want to use the track just for hanging out.
