We looked for quite awhile for a 2 drawer file cabinet, this unit popped up on sale. Heavy, yes. 
Assembly was easy enough, few faults in the instructions. I always glue these kind of projects together and also  used longer screws for mounting the sides of the drawers to the rear section of the drawers. After assembling drawer recommend gluing in bottoms with wood glue or hot glue gun to fill gap of routed sections. Unit very sturdy and holds plenty of files.
