Pressed wood with veneer. When I was putting it together they have you put hinges on after lid is on trunk. PUT HINGES ON LID THEN LEAN LID TOP AGAINST A WALL SO IT CAN'T FALL AWAY FROM CHEST AS YOU ATTACH HINGES TO TRUNK! My lid flopped back without support and ripped back edge of lid clean off. Wood glue, pipe clamps, dark shoe polish and 24 hrs later I was able complete assembly but the tip I just gave u would have saved me a bunch of hastle!
