The GM31850 would be a popular commercial playground system for children aged 6-23 months. There is a Big Leaf Roof, which can be a nice sheltered area for kids to hang out as they play. The Bubble Panel under the roof allows kids to see out and stay active with their friends. There is an easily accessible entrance between the 4 in a Row Panel and Bench Panel, but also has an additional secret entrance and exit through the Crawl Tunnel. Kids can learn letters, numbers and more on the playground with the Alphabet & Number Panel. The Store Panel also provides a pretend play for children that they can learn how to co-operate, to become responsible and how to share responsibility.
