Testa Seat began in 2015 after an industrial design student saw outdated seating limiting children at a rehabilitation hospital. Now operating as a small, Pittsburgh-based crew, the company makes custom-fit supportive seats for children, using in-house 3-D printing and production to keep the work personal and affordable. In 2023, Testa Seat moved its manufacturing to Pittsburgh and reported delivering more than 800 seats through partnerships with clinics across North America and Europe.
