Ergonomic back support on this kids study chair helps align the back and waist while children read, draw, or work at their desk. A breathable mesh back and seat promote airflow, and the sponge padded 15 x 15.5 in seat helps reduce pressure during longer sitting. The gas lift lets kids raise the seat from 16.5 to 21 in with a simple side lever so it fits most desk heights and ages. A strong 5-claw base with smooth-rolling casters supports up to 250 lbs and allows easy movement around the room, while the armless design saves space under the desk.
