Although you can use almost any kind of chair for your child's homework station, a student secretarial chair is probably your best choice. It lasts longer because both the seat height and back support can be adjusted as your child grows. Prices range from under $20 to $50 or more.
As a rule, the better the upholstery and the more adjustable the chair, the higher the price. Look for ready-to-assemble student desk chairs at the same local stores that sell desks. Since kids can be rough on furniture, look for solid construction on any kind of desk chair you buy.
When shopping for a desk chair, look for one with fire-retardant foam, an adjustable seat height, a 360-degree swivel base, smooth-gliding casters and durable upholstery. Be sure to bring your child along to try out the chair in the store. It should be easily adjustable and allow the student to move freely while maintaining support for back, legs and arms. When seated, your child's feet should rest flat on the floor, allowing several inches of knee space under the desk.
