Using this dining table set is a breeze. To adjust the table size, simply use the extendable mechanism on the round MDF table top. For small family meals, keep it in the round shape. When you have a big party, expand it to an oval to fit more people. As for the chairs, just pull them out from under the table and take a seat. The ergonomic design will keep you comfortable. When it comes to maintenance, use a soft, dry cloth to clean the table top regularly to keep its natural beauty. For the PU chairs, a mild cleaner can be used to wipe off any stains. Avoid using sharp objects on the table and chairs to prevent scratches. Also, keep the set away from direct sunlight for long periods to prevent color fading of the table top and chairs. The metal chair legs should be checked periodically for any signs of looseness, and if needed, tighten the screws gently.
