When I tried this chair at a Staples store it was super comfortable and the seat had a nice “bounce” to it. When I received this chair after purchasing online and assembling it it did not have that same “bounce” and the seat also wasn’t as far back as it was at the store (I thought in-person I had more of a seat length than mine does now). I am sure I bought the same chair but it’s tricky because what the tag in store labels this chair and what the website labels this chair is different so I tried to use whatever numbers would match. This chair is fine for I would say up to 5 hours of straight sitting and then I need to stretch but I would not say upto 8 - 10 as indicated. The tilt and head rest are very comfortable too. The arm rests only adjust up and down and do not swivel side to side. I will say it was easy to assemble; parts were clearly marked and packaged and the instructions had clear illustrations.
Wasn't sure if this would be another chair that wasn't made right. However this chair impressed me because of the craftsmanship. It's comfortable and ergonomically correct. Plus I like that it has locking casters so I can put my feet up under my desk. Sometimes when I've been sitting a long time my legs ache but this chair has helped my problem. I love it!!!
