Heavy duty particle board with photographic wood finish on all pieces.  Looks nice enough but is obviously not real wood to a critical eye.  Cam locks bent easily if turned even a little too far.  Easy assembly but took some time.  Lots of storage space with side door shelving design.  Shipping box was pretty well beat up and re-taped but all pieces inside were miraculously undamaged, and all parts were present and accounted for.  Can't believe a 100 lb box shipped for free.  Overall we are satisfied, it is nice enough, solid enough, and a good value for the price paid.  Perfect height, width, and depth for our corner application.
