Very nice box spring assembly  was very easy to assemble but the tool they give you to tighten the 12 carriage bolt nuts was a joke.  If you dont have a  rachet & socket  set  or the next best thing an adjustable  wrench with an 8" or 10" handle  you'll be there for a long time tightening  up the bolts with the tool they give you. I just tossed the tool into the trash  ( it only has a 3" long handle and  it's only a 1/8" thick.  If you have the proper tool and a drill with a phillips tip driver on it  ( to fasten the slats to the box spring )  you'll be they there for hours turning the screws.  But it came out great with  the proper tools and is well made .  Would highly recommend  this box spring, the price was really great.
