Using your new 3 - Piece Nesting Coffee Table Set is a breeze. First, assemble the tables by fitting the tabletop and cabinet together. It's a seamless process, so you can have them set up in no time. You can stack the two tables for efficient storage when you need more space in your small living area. To use, simply unstack them and place items like books, drinks, or decor on the thick marble - grained tabletop or the brown glass surface. For maintenance, wipe the tables with a soft, dry cloth regularly to keep the high gloss black finish looking shiny. Avoid using abrasive cleaners as they may scratch the tempered glass or the tabletop. If there are stains, use a mild soap and water solution. Also, be careful not to place extremely hot items directly on the glass or tabletop to prevent damage. With proper care, your coffee table set will last for years and keep enhancing your living space.
