Holy fat man! This chair is the best chair I have ever purchased for my home. It is very similar in quality as the sort of furniture you see in a well appointed office. It is very well made. It is comfortable. And my 375 hulking mass does not even seem to strain it. The last office chair I bought broke the center pedestal hydraulics in under two weeks of use. It was small as all get out, smaller than what I normally see in a real office at a major corporation in the cubicles of the drones. It was sort of comfortable in an uncomfortable way.This new chair is a *real* chair and not one of those cheepos you get at Office Depot for $34.99. It does what it is supposed to, it has a decent amount of adjustability, and fat beggars cannot afford to be choosers. This works, does not hurt my butt or lower back, is more than roomy enough, and the casters are smooth and strong.I was worried about dripping $300 on a stinking CHAIR for my computer desk, but this was absolutely worth every penny to both me and my largish wife (sorry, honey). Recommended.NOTE: The Allen key included with the hardware package, as is the norm for single-used trash tools, is a genuine POS. Use a long Allen key if you have a set. I cannot remember offhand which I used, so get both your metric and your SAE sets. These screws all have a Loctite-type of dried blue stuff on them. It is hard to turn them in after a few threads. The four that hold the base to the seat are LONG and will require you to whale on that Allen key for some time. Because of this I recommend you use heavy gloves when assembling this. Also, this is why you need to use a LONG Allen key if you have one. It will give you a LOT more leverage than the short one that is included. Also, this is a heavy chair. The box was like 64 pounds and the parts can be hard to lift if you are sitting on the floor to assemble this. Finally, my casters never did "click" or "snap" into place; the instructions tell you to listen and feel for this engagement. The holes in the base are partially packed with grease and there was NO feedback to let us know the casters were locked in place. I had my wife stand on the base with one foot (placing it on carpet and a towel to make sure it did not shoot out from beneath her) and this seemed to drive the castes home. Or home enough. ;-)Great chair. If you are a big boy like me and are tired of junky chairs that cannot hold your weight or are uncomfortably small, this is something to consider, despite the price.
