I spoke with a friend about having head support and adjustable features like this one. I like the mesh and think the features are big improvement on the old leather one I had.
The mesh construction on the bottom is horribly inadequate after a few weeks of use it is sagging almost to the point of touching the frame it is way to stretchy and weak creating a hammock effect putting all your weight on the sides of the thighs. I'm 5'10" 160lbs so well below the weight/size limit for this chair. I've had mesh bottomed chairs before that do not have this issue but they've used a much sturdier mesh material the material used seems to be adequate for the back of the chair but completely inadequate to have someone sit on. This chair will eventually give you more pain than any chair you've ever sat on unfortunately at that point you'll be beyond Staples meager 14 day return policy. The chair will feel fine when you first use it so be warned it will not last long!
Have to admit this is my son’s chair but haven’t heard any complaints and he is in it hours on end. Was super easy to put together. Some parts are better with two people vs one. Took us about 20 min. Love the mesh for easy clean up and the lumbar support. He is 6’2” and head rest seems to work well for him.
