Overall the chair is very narrow and does not have room to move around. This is my biggest problem with the chair. Now I know this is not a Herman Miller chair like the one I have at work that is extremely comfortable. This chair becomes rather uncomfortable sitting and working for hours at a time. I plan on taking it back and trying another chair.
This chair is well made and I can tell that it should last a very long time. But the details in the description weren't very good...as I was looking forward to using the head/neck rest it unfortunately doesn't work unless you are a shorter person. For me it sticks out into my shoulders and is very uncomfortable. We removed it all together so I could use the chair.
I have a small business here in Vt. We have tried lots of work chairs; this is by far the best and most comfortable chair for sitting along time. Your back is supported and you don't sweat in this chair. I would recommend anyone who has to sit for a long time to buy this chair. I've purchased 6 so far.
This chair has really good lumbar support which is rare to find in a lower priced chair. The chair has a padded "bump" behind the mesh in the lower back region of the chair back which eliminates the need for that extra pillow on your chair. The head rest is a good bonus but isn't really needed since I shouldn't be napping at work (but I do like it)! The arm rests are good and adjustable which helps my shoulders stay upright. The back of the chair (not the base) tilts back which is also a bonus. It was pretty easy to assemble. The mesh is okay I would prefer more padding in the seat. I wonder if the mesh will last over years. My only complaint is the mesh but will see how it holds up over time. I got this chair on sale for $100 off which feels like a fair value for the price. My old chair lasted for a decade so hopefully this one will too. It's a good chair if you want lumbar support.
