We have been really happy with this coffee table.  The materials are high quality and the size and shape are perfect for our more narrow living room.  This thing isn't too big but still feels substantial enough to fix our couch.  Assembly couldn't have been easier - there are two main wooden pieces that connect via legs that screw in (no tools necessary).  You can add casters to the bottom but we did not.  I am not really sure what they are there for.  Overall we have been extremely happy with this purchase and it really ties the room together.
