Very substantial, high volume of storage, just be sure you can handle this very heavy piece. The Fedx man refused to bring it up 4 stairs and into our house.  Clears directions.  Assembly took me 2.5 hours.  I unpacked it downstairs and brought the pieces up to bedroom one at a time, inventoried all the pieces and hardware then took my time. Having assembled many items from various manufacturers of both composite and solid wood pieces, I would rate this as one of the easiest.
