I have trouble getting my wheels into place when assembling the chair, how can i fix this?
My gas piston does not go up or down, did I assemble it wrong?
I noticed that I need to remove the red protective plastic cap on the gas piston after I assembled the chair, is there a way to do it once already assembled?
I am having a really hard time getting the screws into the backrest while assembling the chair, is there something wrong?
I don't understand how to attach the lumbar cushion, what do I do?
