Where to begin. Right off the bat, the massage function chord is too short so unless you have a plug almost directly beside the chair you cannot use it. 
We purchased the chair for our daughter's birthday in October and after only having it for a couple of months, the armrests keep getting loose to the point where we have to tighten them daily with an allen key. 
The chair is no longer comfortable either. Cannot sit in it for more than about an hour. Really disappointed with this purchase. Would return it but are past the return window since I have purchased $100 chairs elsewhere that are comfier than this chair and we don't need to tighten the armrests.
