Chair is really comfortable. I am 5’10”. The head rest hit me at the shoulders. Regretfully while installing the headrest one of 2 of the screws stripped. The height of the head rest was annoying so I removed it. Luckily the stripped screw pulled out without damaging the chair.
With the transition to working from home I could no longer sit in my dining room chair for more than 2 hours without my back hurting. I purchased the chair because of its ergonomic features with height lower back and headrests adjustments.
I looked around for a good chair at a good price that I could sit in all day and I found it: Staples Hyken Mesh Task Chair Black (23481-CC) I'm very happy with this purchase.
