A double-panel backrest follows the curve of a child's spine as they lean, which matters more than it sounds when homework runs long. Seat height sets between 14 and 17 in, so the chair keeps working as a child grows through primary school. It carries 220 lbs on a metal frame - far beyond what a child weighs, which is what stops the frame flexing over years of use. Foam over polyester at 10 lbs, measuring 19 x 15.5 in on the floor and 27 to 30 in tall. For ages 3 and up. Pink, blue or gray. Dual back panels are the defining feature of this kids study chair. The seat height adjusts for a growing child, while polyester-covered foam cushions the seat. Its metal frame supports the chair through daily homework use. The compact footprint fits a bedroom learning corner or a small study desk. This kids desk chair suits a homework or study space. Seat size: 15" x 13.5"
