A child who is growing an inch a year should not be sitting in a chair that stays the same size. This study chair moves with them: the seat lifts from 16 in to 20.5 in on a smooth adjustment lever, the footrest steps from 4 in to 9 in so feet stay planted rather than dangling, and the armrests lift 1.8 in and rotate 90 degrees to get out of the way when a desk is crowded. Each of those small adjustments is doing the same job, keeping hips, knees and elbows at sensible angles through a long stretch of homework. The backrest is mesh, which matters more than it sounds in a bedroom that warms up through the afternoon, and the seat is padded and removable so it can be taken off and cleaned after the inevitable snack. A five-claw base with universal wheels keeps the chair stable while letting a child swivel to face a parent, a sibling or a bookcase without climbing out. The frame carries up to 330 lbs, so it is not a chair anyone will outgrow structurally.
