This is a major piece of furniture.  We ordered in king size, and it took 2+ people about 2 hours to put together.  The wood is a heavy MDF with a walnut veneer - we ordered room delivery for $40 and it is worth it.  As others mentioned, it is low to the ground.   We love the contemporary, clean look of this piece.  It pairs pretty well with the Hali 2 Drawer Nightstand on Wayfair (the nightstands are a little darker walnut).  We're showing it here with a 12" mattress, so a lot of the headboard gets covered by pillows.  The only negative is that the mattress sits slightly below the side edges, so you have to lift the mattress up to put on new sheets and it's a knuckle buster to stick your hand between the sideboard and the mattress.  I've included some pictures from the assembly process.
