I needed to get a second one delivered because the first included only two left-sides of the frame. The second again had two of the same right-side piece so thankfully it worked with the initial unit. With that resolved, this is still a terrible desk. The corners were crunched on two shelves even though the box was undamaged and I ended up unable to screw in two of the nails because the wood holes collapsed. If I didn't need this so urgently I would have returned it outright.
