The Free Standing Mikros Pod Climber (Set of 4) set contains four separate climbing posts with an interesting design that kids are bound to love. Unlike our other models of pod climbers, these are approved for preschool aged children because of their relatively short height and number of steps (although safety surfacing is still required). The circular shape of the steps allows them to be climbed from any side. If the posts are installed adjacent to each other (which is recommended), kids can also step from one to another. This way, they have a number of different directions that they can move from any point on the climber. There are vertical handrail posts on the top steps of each climber, which ensure that there will always be a secure place to hang onto, especially when stepping across the tops of the posts. These can also be installed alongside other pod climbers for even more places to climb.
