The pros, easy to put together, The chair seams of good quality and is sturdy. the cons; the seat cushion isn’t very padded therefore it’s not as comfortable as it could be and the electrical cord that runs the vibration/heat comes out of the back of the backrest of the chair. That means when you swivel, the cord swivels with you.  This I can see as being a tripping hazard or just a hazard in general.  I wish it was more comfortable, after a few hours at my desk my tailbone starts to hurt. For the price I paid, I was hoping for a little extra comfort!
