This is my first mesh chair and the first one with adjustable arm rests. I had shoulder pain. I thought that it may be my working position. After buying this chair and adjusting the arm rests I have not noticed my shoulder pain. I have also had back problems in the past. This chair has good back support.
Wife loves the chair. Took me 20 minutes to assemble. Easy instructions very easy packaging to understand instructions. I've put a lot of store furniture together through the years wish they were all packaged this way.
I love it so far. Assembly was straightforward it feels large enough for someone who’s 6’2 and has great lumbar support. I highly recommend this chair.
