Using these chairs is easy. Just assemble them according to the included instructions, and they're ready to be placed around your dining table. When having a gathering, invite your guests to sit on these comfortable chairs and enjoy the luxury. As for maintenance, regularly vacuum the upholstery to remove dust. For stains on the polyester fabric, use a mild detergent and a soft cloth to gently clean. Avoid using harsh chemicals as they may damage the fabric. Also, be careful not to drag the chairs across the floor to prevent scratches on the non - marking foot caps. Keep in mind that due to COVID - 19, there may be delays in getting replacement parts if needed.
