Requires assembly and took me the better part of an afternoon to put it together, but the instructions are clear and all the pieces included and in good shape. Suggest you assemble it in the room where it's intended to stay since it is quite heavy. I didn't glue the little pegs in as a precaution against reading the directions incorrectly, and it doesn't seem to have mattered. It looks very smart and there is ample space for books, etc.
