Using this chair is a breeze. Just place it on a flat surface and let your child sit comfortably. Since it's stackable, you can easily store multiple chairs when not in use by stacking them up to 15 high. When cleaning, you can wipe the seat shell and frame with a damp cloth. For the vented back and drain holes, make sure to clear any debris that might block them. Keep in mind that although the chair has a 440 lb static weight capacity, it's recommended for 3rd - 7th grade students. Avoid dragging the chair on the floor to prevent damage to the non - marring plastic floor glides. The frame has a limited lifetime warranty, so if you notice any issues with it, reach out to the manufacturer. And because it ships fully assembled, you don't have to worry about any complicated setup.
