Bests & Worsts Reviews from Amazon

Having just received these chairs after reading a good number of the reviews, I was shocked to find that while many reviewers complained that the locking mechanism did not "hold" the chair in position effectively, no-one mention the finger pinching potential if you grip the arm above the knob allowing your fingers to get between the top of the knob when in the upright position but if left there when moving the chair to full recline the space between the underside of the arm and the knob diminishes to nothing resulting in a very painful finger pinch. VERY DANGEROUS!! I removed the knob and locking mechanism to eliminate this hazard and still found that the chair stayed put in any position relying on the natural balance that results from the inherent zero gravity design.
