We bought one of these chairs and when you lean back (not heavy people or leaning back hard) the back mesh rips out from the side of the chair. We got a replacement chair because of this and the first time I sat in it (I am 150lbs) the new chair did the same thing.
This chair has held up tremendously. I bought it pretty quickly in 2020 and 8 hours a day for a year plus most days in 2021 and then about half the days in 2022... durable no problems at all. great back support the seat is comfortable as well. My daughter asked for the same for Christmas in 2020 and she's WFH more than I am and also very pleased.
