Been using thid chair for a couple of months now and so far it is gotten more uncomfortable each day. It  is wider than I anticipated and there seemsto be a spring in the middle that also adds to the uncomfort. For being short stature and petite, it is not a great design. I didnt realize that this came with what they call a massager for the back, basically it just vibrates a lot and doesnt really do much so that was a bummer. Also in order to use the massager, you have to plug it in via USB and if you are using your pc, be careful it will go flying.
