So far so good! Beautiful chair and it’s pretty comfortable. It’s meant to keep you straight so u don’t slouch, especially if you work 8 hours a day, but if u do ever want to “lean back” it does allow u to tilt back a good amount and locks without an issue. You just have to unlock before going back on the upright position because if u try sitting up with it locked it sounds like the tilt bar snaps. So u want to be careful with it. I am happy with my purchase!
