I purchased this chair in Sept 2022 and have been using it as my work chair 8 hours a day 5 days a week. In December of 2022 I noticed the mesh was starting to stretch even though I'm under the weight limit (195 lbs). I ignored it because I expected it stretch... some. It's now March of 2023 and the mesh of the seat started to rip away from the frame. Totally unusable now and very disappointed.
I was not 100% of Mesh material however it’s surprising me so far. It’s comfortable and doesn’t loose it’s comfort for the several hours I use it for work each day. I would recommend. Try it out before buying to be sure it will work for you. Everyone is different.
