I constantly order items that require assembly and this one was in the top 2 hardest to put together.  First, if you live alone, walk on by.  It is very difficult without a 2nd set of hands.  The directions were ridiculously sparse, which caused a lot of install, uninstall, install a different way, uninstall, turn around reinstall maneuvers.  No explanation on the when to tighten the support bars so there were a bunch of tighten, loosen, tighten, loosen attempts.  After about  4 1/2 hours of wrestling with the frame, you get to the glass and pull off the stickers and they leave sticker gunk on the glass.  Not a fan.
