I’ve had this chair for several days now it was easy to put together. Took less than 30 minutes for me. It is comfortable and adjustable easily. I like the mesh fabric keeps me cool during the day. The arms are perfect tight and also adjustable. I do not use the neck rest very often but appears to be at the right height You can push back on the back rest and it leans back and when you lean up and comes back the place. The only adjustment is for up and down that you need the lever for. And the arms of course have a lever to adjust them as well Overall it is a great purchase
This chair doesn't sit straight with the tilt lock in place and the tilt tension tightened there's so much play in the tilt lock you lean back too far. Chair is 6 months old and the lift cylinder creeps down during the day.
Very easy to assemble definitely recommend using a socket wrench if you have one (saves a ton of time). Very comfortable chair have been using it for a few weeks now and no back pain. Would recommend this chair to anyone who loves the color blue :D
