This bench has a metal base with adjustable legs so it is easy to level it on an uneven surface.  The seat is made of hollow metal which has been covered with a composite material about 1/8 " thick with the pattern of wood pressed into it.  It looks quite realistic and you can't tell there is metal underneath unless you knock on it.  It arrived with a piece chipped off the side about an inch long and 1/4 inch wide but it comes with a repair kit so we decided to repair it rather than return it.  It looks just fine and we've put the damaged side against the wall.  If the top had been chipped, I think we would have returned it.  Had it arrived without damage I would have given it 5 stars.
