The connector plate that connects the seat to the chair seat screw holes did not match up. That caused one of the screws to not go in properly and cross thread and get stuck about a quarter of the way in. It took alot of force to get it out. Once I got it out I confirmed it was not something I did wrong but the screw part in the seat was definitely not manufactured properly. I was deeply disappointed to also find out that a PLASTIC connector connects the back of the chair with the seat bottom - NOT METAL. Lean back a few too many times and I can see the back completely snapping off. The bracket looked to be metal at the store but it turned out to be shiny plastic that looked like metal. Deeply disappointed.
The arm-rests are well padded. My lower back isn't acting up as often. I like the Color trim. If you you to tuck in close to the keyboard like me then the raiseable arms are a deal-sealer. No neck-pillow. So i bought my own for $11. but now the chair is perfect.
