so i just got a new chair for my desk. In the store it reclined fine, when I first put it together it reclined fine. I wound up turning that nob on the bottom. Its a big black round nob you can rotate several times left or right which I know is for the reclining function. Now no matter which way I turn it, it seems to only recline a little. What is the logic behind it? each time i mess with it, it seems like neither direction has a definite impact on the reclining capability. Im going crazy with this thing!! i just wanna lean back forever!!!
