The Theorem stack chair from Smith System is a solid shell classroom stack chair perfect to support high school learning. The contoured chair offers two major seating positions- working and slightly reclined. Theorem provides the feeling of continuous support ,whether the student is sitting for work at a table, or looking up to participate in classroom discussions. The chairs seat is contoured 5.5 degrees, which is deeper than your typical stacking chair. This helps position the sitters weight back into the seat for a more supported upright sit. It also makes the angle between the top back and seat more shallow (about 90 degrees), so the sitters upper back is balanced over the lower spine the lumbar region always stays in contact with the chair.

Smith System high-tech gas-assist injection molding not only keeps the seatback strong and flexible, but it eliminates the exposed structural ribs on the back of the chairs shell. Its sleek and calm, yet familiar. Its a crossover chair that quietly blends in anywhere: classrooms, cafeterias, flex studios, maker spaces and more.
