Nice looking chair.  Love the swivel ability.  Problem that I have is after six weeks of use, the motorized feature seems to be failing.  The chair will not return to upright position without holding the button and pushing down real hard on the foot rest to engage upright position.  Not an easy task as I am recovering from knee replacement surgery.  Love the usb port for charging my cell phone.  Back position is very upright and firm.  I have experienced back pain because of the curve of the chair as well.  My head won't touch the back when seated so have to add a little pillow to make myself comfortable.  Firm seat which does help me get up from sitting which has helped with my recovery.  I love the small size of the chair as I am 5'.  Wanted to love the entire chair but would not feel good about recommending this to others.
