They were very dirty and a little rusty. They also needed new desk tops. I gave them a good scrub, repainted the metal, and replaced the tops. I only spent $15 for plywood, $3 for spray paint, and $3 for new screws for a total $21 for 3 desks which is still less than the price of one new desk without shipping.
I decided to leave the chrome legs off until I can find chairs for them to sit on. For now they are the perfect height for the boys if they are sitting on the floor.
