The chair was easy to put together. Seems sturdy enough. My problem is that the headrest can not be adjusted height-wise. I am 6'4" not extremely tall and the headrest sits between my shoulder blades. This would be a 5/5 chair if I could raise the headrest.
It is well built and comfortable. Assembly is easy. I especially enjoy the slight rocking motion of the back. The only shortcoming for me is that it is a bit too heavy. And I wish the headrest can be more adjustable.
Seat cushion is very firm. An older version of chair in office has softened into a more comfortable chair with time. This is the 4th chair of this model that we have purchased for the Office. I especially like the height of the cushion. I am 6 feet tall and have found that some chairs over time do not keep their height and they slowly collapse and it is like climbing out of a hole to simply stand up. On a side note the chair was damaged in shipment and Staples quickly in an overnight shipment replaced it.
