It's good but the wheels were kind of sticking so I replaced them with the wheels from the original chair. Also the headrest doesn't tilt back and forth as easily or slide up and down but that's actually a really good thing because on the old one it too easily slipped down when I didn't want it to. I'm guessing this level of stiffness is actually correct and it was the old chair that had it wrong.
This chair is very poor quality especially for the almost $200 asking price. Maybe worth $30? But even then. I have had this chair since September 2023 - it is now November 2023. I use it approximately 6-7 hours per day and I weigh less than 200 pounds. This chair is already starting to fall apart! See photo. Also this chair is meant for very short people. I cannot even use the included head rest. It isn't adjustable enough. I wish I had not purchased this chair.
