Was pleasantly surprised with this chair - it was recommended by a coworker. You can adjust the headrest lumbar support resistance on the reclining and height of the chair.
Absolutely a fine yet rugged piece. Nicely finished no rough edges to cut oneself during assembly. The materials are perfectly suited for the necessary functionality this chair is capable of performing. No flexing no fear of over adjusting or restricting use to compensate for design flaws. I have not noticed any such flaws. Assembly was intuitive and directions spot on. I used a T-handle hex wrench a nice set of tools to acquire for all assembly projects by the way. One thing I had to do was drill out some excess plastic in one of the arm mount screw holes with the proper sized bit took 10 seconds went well. Chair is perfectly suited for my 6’2” 220 pound body and that’s at the upper range of the device. I had a moment when the back stopped movement so I check the manual problem solved. Definitely highly recommend this well engineered task chair.
