Tippy Stool

This is a stool made from tri-wall cardboard. The bottom is curved to allow for some rocking. These stools are used in classrooms for students who need some sensory stimulation.

The dimensions I provide in this Instructable are what I use in my class. They should be modified for the person who will be using the stool.

I learned cardboard carpentry at the Adaptive Design Association.

You need to seal off the edges to help keep water out. I use gummed packing tape. You can look at this video from the Adaptive Design AssociationYouTube channel

To finish the footrest, you need to apply primer, paint and polyurethane. I use water-based products to make clean-up easier.
