Activity Chair

The ultimate in active seating for pediatric to adult clients

One chair, many lives

Therapists everywhere tell us the Activity Chair is perfect for feeding, speech therapy, active learning and for clients with sensory processing challenges. Not only that; parents see what it can do for their child in the classroom and realize how much they need it at home, too.

The Activity Chair has revolutionized adaptive seating and continues to delight therapists with its versatility for people of all shapes and sizes, all conditions and special needs.
