I received my 3 piece Johnstown patio furniture today.  I was able to assemble myself.  
My only concern was the Allen wrench it provided was a tad too small to secure the bolts on the chairs. It worked fine for the bolts on the table, not for the bolts on chairs.  I attached a picture of the bolt head and the allen wrench it came (smaller of the two pictured) and one I had. Clearly the larger one I had fit better.

Besides that ONE issue, this set is perfect for my small patio. 

The ease of assembly and the quality and sturdiness makes this a great piece. 

Highly recommend!!!!

It came with extra foot extenders to help balance a table  and configure it if you must.
