Hand crank height adjustment lets this kids study desk and chair set adapt as children grow, with the desktop ranging from 21.6-27.9-in high and the chair seat from 11.5-15-in high. The 31.5-in wide tilting desktop offers separate angles for writing, reading, and drawing so kids can match the surface to each task. A rotatable 11.5 x 8.5 in book stand keeps pages at eye level and frees up workspace on the desktop. The partition drawer, cup holder, and pen slot group supplies within easy reach while keeping the study area tidy. A breathable seat and supportive backrest pair with a footrest bar to help kids sit more comfortably during longer study sessions. The desktop supports up to 176 lbs and the chair supports up to 220 lbs for everyday use by children ages 3 years and older.
