It’s hard to concentrate in a room full of fidgety bodies. That’s why SmartLink seating gets extra credit for being so responsive. This set of four 18"H 4-leg chairs features a single piece seat and back called the Learning Curve, which supports a wider range of movement and allows students to turn around, sit sideways, or lean back, keeping them comfortable and focused on the lesson. The armless design fits snugly underneath any desk, and stacks five high on the floor to save space when it's time to clear the room. Glides or casters make it easy for anyone to move, which makes this SmartLink chair appropriate for any age or classroom.
