Solid wood with bright white satin painted finish. Only assembly is screwing the legs into metal brackets bolted securely into the underside of the desk - easy and sturdy. Ordered 2, one set of legs wasn't quite as tight a fit as the other, but it is more a slight cosmetic issue, not a functional problem. Both boxes came severely damaged, and the desks tops each had slight puncture type impact marks. Great Offer Stock offered fair compensation so I kept the desks. Very nice looking, would purchase again.
