Great value, sturdy, looks great. 
Easy to recover seat should the need arise. 
Easy assembly, no missing parts. 
Heavy steel, will last a long time.

Assembly instructions are adequate but not fabulous. 

Medium Phillips head screwdriver, small crescent wrench, hammer. 
8 bolts, 4 nuts.  

Requires some wrist strength, and finished stool is perhaps heavy enough to hurt a back when carried. 

Use the thick cardboard on top of the packaging as a work surface. 
Put the glides on 1st, matching their angle to the leg angle. 
Then attach swivel using 4 small bolts and nuts. 
 Use a table top to set cushion and back upside down, and align swivel (with attached legs upside down) using 4 long bolts.
