Solid wood. Top is over an inch thick and very heavy don't try to lift or assemble alone.   Iron supporting struts underneath and legs are thick & strong.  Wood very well finished, joins tight & barely visible.  Raw edge is lovely, lightly sanded to me smooth & not catch, but still a little bark in the nooks & crannies the wood is beautiful with knots & lots of grain visible.   Very sturdy, a last a lifetime piece.
