Using these dining chairs is easy. Just place them around your dining table or in the desired room. When sitting, you'll feel the comfort from the thick cushion and the support from the curved backrest. As for maintenance, use a soft, dry cloth to wipe off any dust regularly. Avoid using harsh chemicals as they may damage the grey finish and the metal frame. If there are spills, clean them up right away to prevent stains. Also, make sure not to place heavy objects on the chairs to maintain their shape and structure. With proper care, these chairs will serve you well for a long time.
