The materials appears to be made of pressed wood, very fragile and easy to damage in transport.  Comes in 3 boxes, two of which had damaged pieces - chips and cracks that were noticeable.  The construction does not appear to be very solid although the materials are extremely heavy.  Lots of pieces to be assembled.  I also paid Handy.com for assembly.  One person showed up who told me this is a two person job that takes several hours.  I had to abandon this although I believe it would be a great space-saver.
