The versatile climbs in the narrow frame make children want to try it again and again. The sturdy coconut rope is an excellent trim trail in its own right, training important motor skills such as balance and spatial proprioception, fundamental skills for example, being able to sit still. The higher level climbing and seating points with the wonderfully bouncy ropes and rotating UFO's on ropes train all muscle groups as children cling onto them when climbing or passing. The narrow passage points train important social-emotional skills such as consideration of others and turn-taking. The upper rungs, UFO's and membranes make nice destinations for a bouncy or swaying break and a chat with a view. All in all, the Explorer Arch is a lot of fun, varied play for a lot of children.
