It is actually very comfortable. Cushions are much better than I expected, it feels really good on my back.
The massage function is kind of pointless and really doesn't do much. I would advise these chair makers to skip that part and maybe focus on the quality of the chair itself. 
The one thing that worries me a little is that it seems slightly fragile. If you are overweight, this chair may not be for you. I feel like a good solid flop onto this thing by a heavy person or careless child could spell the end of its days. For me, a mindful bachelor living alone though, it is perfect.
For the price, it is a wise purchase for budget comfort. Only removed one star for the reduced sturdiness.
