Unlike the advertisements the arms don't move forward/backward nor in/out. I'm not going to unscrew the six bolts to move it 1/2 inch. The arms do move up and down.
This is a nice and comfortable ergonomic office chair. I have issues with lower back pain even with moderate amount of sitting. This chair has helped a lot with providing support at all the right places. I would have given 5 stars if the lumber support had more adjustment room.
Great office chair very comfortable and easy to assemble. This is the 3rd Hyken mesh chair I have purchased. The first one is in our winter home then I bought one for my daughter and now I have one here in our summer home. I highly recommend this model!
