I'm 5'6" so that's probably part of why this chair didn't work for me. I gave it a try because high back regular chairs tend to not have an actually full/high back and are more mid-back or shoulder. Quality seems good, ease of assembly was great. What I can't get over is that sitting in the chair it feels like the seat has a tilt and my butt is lower than my knees. Since you can't adjust it to tilt forward at all it's odd feeling. When the chair is at the lowest it will go the front of my foot hits the floor but my heels don't. Lumbar support is where I'd want it, but likely low for someone taller than me. I had a tailbone injury so I'm looking for a new desk chair to ease that issue... this is not the chair for that. If I try to sit straight up in the chair my back is several inches in front of the chair back. And when I sit up straight it feels like my hip angle is closed, like I'm leaning forward on my thighs a bit because my knees are above where my but is sitting. There is extra thigh support but not much around the tailbone/bum area. Chestnut is a lovely dark brown color.
