Top: Max's slip-on seat fits over his commercially-made classroom chair. His adaptations included lateral supports, armrests, a hip belt, a footrest, and a grab bar so he can transfer from his walker semi-independently.

Right: Jose's chair has a detachable headrest and a removable elbow rest so he can prop his chin in his hand. One armrest slips out so he can get on and off the chair without moving it away from his desk.
