I put this together myself; the only tricky part was that the screws holding the side pieces to the end pieces didn't
seem long enough if used with the washers.  Taking the washers out worked.  It's very nice, rolls in and out smoothly,
and like everything else I've bought from Wayfair, I'm not at all nervous about having it shipped to me because it's
always nice and of good quality.  Thank you!
