Using these coffee tables is easy. First, assemble them as per the instructions provided. The full assembly might take a bit of time, but it's worth it for the great look you'll get. When you have guests over, use the large table to spread out snacks and the small one for cocktails. You can arrange them in two ways. Nest the smaller table within the larger one for a cool two - level display, or place them separately to match different room themes. Remember, items in the picture other than the coffee tables are sold separately. For maintenance, clean the glass top with a glass cleaner and the faux marble top with a mild, non - abrasive cleaner. Wipe the metal frames with a soft, dry cloth. These tables are mainly for residential use, but they can also work in non - residential settings. Keep in mind that there's no storage in these tables, so don't plan to use them for keeping things inside.
