Using this coffee table is a breeze. To adjust the height, simply use the lift - top mechanism to raise it to your desired level. When you're done, gently lower it back down, and the controlled closing hinges will ensure a smooth closure. Before using, make sure to assemble the table according to the included instructions. As for maintenance, use a soft, dry cloth to wipe the surface regularly. Avoid using harsh chemicals as they might damage the faux wood and ash veneer. Keep sharp objects away from the table to prevent scratches. Also, be careful when adjusting the lift - top to avoid any pinch injuries. If the table gets dirty, you can use a mild cleaner on a damp cloth, but always dry it thoroughly afterward.
