The seating cushion is made with good quality material. Lumbar support is fine. Hight & Tilt adjustments are fine too. The only small drawback is the seating width might feel smaller for big guys. But I am an average size person so I have no issues in sitting and getting up. Overall a nice office chair.
Love this chair. Seat goes higher than most which I love. The seat could use a little more cushion but the ones with a cushion make me hot. This keeps me cool. Arm rests are removeable if they get in the way for you.
I am very picky about my office chair since I sit in it for so many hours during the day. It has excellent height and tilt options and the seat cushion is comfortable and supportive.
