Using these Makalu dining chairs is a breeze. Just place them around your dining table and enjoy a comfortable seating experience. When it comes to weight, make sure not to exceed the 250 - pound capacity to keep the chairs in good shape. As for cleaning, use a mild detergent and a soft cloth to wipe the grey polyester upholstery. Avoid using harsh chemicals that could damage the fabric. For the black steel legs, a simple dusting with a dry cloth will do. If you notice any scratches on the powder - coated finish, try to touch them up gently to prevent rust. Also, because the chairs contain Nickel Compounds which can be a cancer risk, handle them with care and keep them in a well - ventilated area.
