it was simple to assemble. but that's it. the chair is uncomfortable, you can FEEL the steel frame after an hour of sitting in it. I'm glad i got the protection plan because the right side of the "STEEL" frame broke right above the hinge, it now is floppy because the left hinge has no structure at all. Put in a claim, will update my review if the service is good. 
The service was good, too bad the replacement also broke. i don't recommend this chair for anyone who weighs over 200lb, suffers from chronic pain, and/ or those who have to sit at a desk for more than 3 hours at a time..
