Basically if you're looking for something ergonomic and posture fitting like a reputable european brand that usually sells their models in the $1k-$5k range this is the perfect alternative. I started a new job that had a nice looking chair but it killed my back after the 2nd day. This chair fixed it all. No back pain after the first day and no back pain after a week.
This chair is great but I am just a little too tall. The headrest would dig into my shoulders so I did not put it on. I am 6'3 for reference. I wish the Dexley chair had tilt lock as it would make it more appealing to me.
