I ordered this chair for my work from home desk. It is bigger than I'm used to. But so very comfortable for all day use. I do not regret choosing this chair. It has been a great choice.
Putting it together was a little frustrating. I was alone so that may have contributed to the hassle. Attaching the seat back to the armrests lining up the bolts took a few more minutes than I expected. That being said the assembly took about 30 minutes. The seat is minimal as far as features. It rises and lowers it tilts. It swivels. The best feature is how comfortable the chair is. A cross between pleather and vinyl. I bought it on sale and if it lasts it will be a great value office chair.
The Vortex chair is reasonably priced and of solid quality. The chair has helped ease my back problems and is a pleasure to work in. The only drawback is that it was difficult to assemble.
I'm pretty handy so I opted to put the chair together myself. First using the little allen wrench they supply would be a real pain luckily I had a set of Sears allen's with t-handles that made screwing in the bolts a bit easier. I had a real hassle lining up the holes for the seat back bracket to the seat took a while to get that done. Other than that it's a comfortable chair to sit in while doing office work even if its supposed to be a gaming chair.
