Very cheap particle board.  Had one leg screwed in and picked it up by the leg to position for the install of the second leg, and it ripped right out.  I thought about the return process and decided to just glue it together and keep it.  It matches my furniture and has the look I want, and for $100 delivered it shouldn't be judged on any quality merit's whatsoever.  Its a good looking cheap coffee table that can easily be replaced.  Its good enough for now, which is what I want.
