Theorem® two major seating positions — vertical and slight recline — are perfect to support high school learning. The chair’s seat is contoured 5.5 degrees, which is deeper than your typical stacking chair. This helps position the users’ weight back into the seat for a more supported upright sit. It also makes the angle between the top back and seats more shallow (about 90 degrees), so the user’s upper back is balanced over the lower spine; the lumbar region always stays in contact with the chair.
