1. This chair is not the proper size unless you’re extremely short. The headrest is literally lower than my neck and extremely uncomfortable. It’s not a headrest unless you’re less than 5 feet tall. I’m 5’9” which is pretty average height and it’s nowhere near being high enough to be a headrest. And it didn’t adjust higher or lower. 2. As other reviews have said the lock function is not really a lock. The chair still tilts back at an uncomfortable angle. I bought this chair to improve my posture and because I needed a headrest. It’s worse than the chair I have. Extremely disappointed and now I have to go through the hassle of taking it apart and returning it.
I was shocked how great it feels in this chair. I had two previous chairs and they seem to start out being great but don't hold up! The cushion segments and they look comfortable but did not hold up!!
The chair is awesome but I think the headpiece needs to be adjusted to be able to go up and down vertically for people who may be a little taller. Other than that great chair
