Using your emu Mom 640 Outdoor Arm Chair is a breeze. Just place it wherever you need seating, like in your restaurant, patio, or backyard. The stackable design makes it easy to store when not in use. When sitting, you'll enjoy the comfort of the solid steel slat seat and back, and the ergonomic design. As for weight, it can support up to 300 pounds, so most people can use it without worry. For maintenance, since it's e-coated and powder-coated, it's resistant to fading, peeling, and rusting. But it's still a good idea to clean it regularly with a mild soap and water. You can also replace the non - slip feet if they show signs of wear. Make sure to place the chair on a flat surface to keep it stable and avoid any accidental tipping.
