Using this chair is a breeze. Just place it where you need it in the classroom or other suitable areas. It's great for 3rd to 7th - grade students to sit on while studying or doing activities. When you're done using multiple chairs, you can stack up to 15 of them together to save space. As for maintenance, simply wipe the navy plastic seat shell with a damp cloth. Make sure to dry it thoroughly, especially if you use the dry - assisting drain holes. Avoid dragging the chair across the floor; instead, lift it to prevent damage to the non - marring plastic floor glides on the chrome frame. If you have any issues with the frame, remember it comes with a limited lifetime warranty.
