Theorem Adjustable Height Chair

AVAILABLE SPRING 2019

A new seating line designed for 9th to 12th-grade students. Two major seating positions — working and slightly reclined — are perfect to support high school learning. Unlike traditional school chairs, Theorem provides the feeling of continuous support, whether the student is sitting up for table surface work or looking up to participate in discussions. Shell available in 10 colors, 5-star base in black.

• Adjustable height from 16-21”.
• Unique nylon shell offering unmatched strength and flexibility.
• Available with 2” casters or glides.

Theorem’s 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 sitter’s 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 sitter’s upper back is balanced over the lower spine; the lumbar region always stays in contact with the chair.
