I have been using coroplast for years to make things out of, and have used it to adapt seating, make clothespin games frames, make guinea pig cages, and to make other things around my house and therapy office. It is a corrugated plastic, so it is a lot like cardboard, but it is plastic. I use Tri-wall to make little chairs and trays out of, but the cool thing about the Coroplast is that it is easily cleaned because it is a plastic material.
The material is really sturdy, is easy to cut, easy to glue or tape together, and easy to clean. I have a little guy that I used to see for Occupational Therapy, and he had trouble sitting upright, so I made him a little high chair insert for his high chair.
First I cut it to size, and hot glued three pieces together to make it sturdier. Then I cut holes in the right places for straps. Finally I hot glued velcro onto it so that I could velcro pieces of pool noodle on it to use as lateral supports and as head supports. I made the straps adjustable in the back using velcro as well.
