Other than taking forever to peel off all the protective plastic. They are easy to assemble with a ratchet wrench, sturdy and attractive. I bought 2 sets, but have only assembled one set. The rubber pieces are okay, but do not completely civer the rough connections between the pieces. Some connections don't fit/meld completely. There is a gap so the finish piece is somewhat lumpy.  It took a little over an hour to prep assemble two beds.
