Designed for children ages 2-12, The Pebble is a great way for kids to develop basic coordination skills through balancing activity. Although sold individually, the Pebble is best suited when arranged in a group together. The Single Pebble is available in a variety of quick ship plastic colors (Pacific Blue, Sunglow Yellow, Rainforest Green, and Tan) and comes standard in Brick Red or Brown paint. The plastic step is 12.2-inches in diameter and 7.5-inches high. The design accommodates 18-inches in-ground for mounting, up to 12-inches for surfacing, with a finished step height of 18-inches or less. This allows buyers to place their Pebbles at varying heights and add to the overall challenge of the equipment. Contact customer service to find out which colors are currently in-stock and ready to ship.
