Using this stack chair is a breeze. Just place it wherever you need seating in your commercial space. When not in use, you can stack up to 5 chairs together to save space. Make sure to avoid overloading the chair, as its weight capacity is 661 lbs. For maintenance, wipe the black plastic back and seat with a damp cloth regularly. Check the front cross brace and sled base frame occasionally for any signs of damage. If there are any issues, refer to the limited lifetime warranty on the frame. Keep the plastic floor glides in good condition to protect your floors.
