These things are so underrated for use in recreational and preschool gymnastics! So many great things and skills can be learned in such a small space.
For example, it makes a fantastic parent tot station teaching climbing up, and down. You can also adjust and use mats to prop up at an angle as a slide down option. These normally cost like a thousand bucks with shipping from gymnastics equipment companies. Amazon has them here for $179.97 with PRIME! What a steal! Not only does it work grip strength, but also works on conquering fears and coordination. It can also work as monkey bar prep ;)
