Using this stack chair dolly is a breeze. First, simply place the sled base stack chairs on the dolly. You can stack up to 30 chairs on it. Then, use the 360 - degree swivel feature to move the chairs around your commercial space easily. When not in use, you can store it in a corner as it doesn't take up much space. As for maintenance, keep it clean by wiping it with a dry cloth. Avoid exposing it to extreme moisture or harsh chemicals as they might damage the black powder - coated finish. There's no need for assembly, so you can start using it right away when you get it.
