This table adjusts in height from 18″ to 30″ making it ideal for a coffee table or small dining table. And it’s so strong, that I could stand on the corner of the top and it would barely flex, so you could use it as a work table too. The threaded screw has a spinning lock underneath to keep it secure. This was a custom piece for a client, and I can remake it or change things around. The top is 3/16″ thick steel and 40″ x 40″ with a 1″ x 2″ boxed frame underneath. Price would be around $1075.
