This chair was easy to assembly and seems well made but will be uncomfortable for tall users. I'm 6'2" tall and the seat back stops about 5" short of my shoulders. The neck support is not height adjustable and starts about an inch from the top of the seat back so it constantly rubbed against my shoulders and I had to remove it.
This chair suits my petite frame perfectly and gives gently firm support. The width is narrower than most other chairs so fits my small space. It has multiple adjustments so can be tailored to suit.
The wheels don’t roll very well. It’s more like they just slide across the floor. Had to remove the head/neck rest as it was wobbly and wouldn’t stay up high enough to not hit my shoulders. Fortunately the seat and back are comfortable and give decent support. A couple of pros and a couple of cons make for a chair that is just OK.
