I have purchased over 10 desk chairs in my life and have never bought one anywhere near this bad. The chair tilts too far back even with the tilt lock in place and with tilt tension all the way up. If you use the backrest like you are supposed to you will sit at a 110 angle if u remove the tilt lock thing. You will sit at a 140-degree angle. The 110 angle is a terrible position and uncomfortable for your neck and back. For the price the quality of the parts is far below what should be expected. I highly discourage anyone to purchase this chair. I am extremely dissatisfied and will never purchase another chair from staples. I would return the chair if it was worth the time to take it apart. I will be buying a new chair from somewhere else.
I am a teacher doing remote learning during the coronavirus pandemic. I needed a comfortable chair so my body could handle hours in front of a computer. The mesh of this chair is supportive and is holding up well. It rolls and swivels smoothly. It was easy for one person to put together- even the little wrench was included all parts were labeled and the different screws were packed separately so they were easy to identify.
