Using these dining chairs is easy. Just assemble them according to the included instructions and place them around your dining table. When sitting, you'll enjoy the comfortable backrest and padded seat. For cleaning, use a mild detergent and a soft cloth to wipe the stain-resistant fabric. Avoid using abrasive cleaners as they may damage the fabric. As for the metal base, you can simply dust it regularly. When moving the chairs, lift them gently to prevent scratches on the floor. Also, don't exceed the weight capacity of 275lbs to ensure the chairs' durability. And remember, since full assembly is needed, take your time and follow the steps carefully during the setup process.
