These Sonia cane dining chairs are easy to use. Just place them around your dining table and start enjoying your meals. When it comes to maintenance, it's important to keep them clean. Regularly dust them with a soft, dry cloth. Don't use oiled or treated cloths on the lacquered parts. If there are fingerprints or smudges, you can use a damp cloth (but not too wet) and then quickly dry it with a dry cloth. For stubborn stains, a bit of mild soap and water on a soft cloth will do the trick, just remember to dry it right away. Also, use felt pads under the legs, coasters for drinks, and placemats to protect the chair from scratches and damage. They are made in China and don't require any assembly, so you can start using them as soon as you get them. Be aware that they contain wood dust which can be a cancer - causing chemical according to Prop 65, so handle them in a well - ventilated area if possible.
