I love this chair. It's super comfy all day long plus the breathability doesn't make me feel like I'm sweating/sticking to the chair if it's a little warm that day. It looks handsome and professional was a breeze to assemble and easy to use the functions. I love that you can lock it in the "recline" tilt back position. I've only had it a few weeks but so far I'd buy another one in a heartbeat. I'm shorter at 5'3" and the seat length is comfortable for my shorter legs.
Assembly was super easy with everything including the hex key provided. The red color is a nice deep red. The assembled chair is 80% comfortable with my issue being the headrest. I think I received a defective headrest because one side bows out way more than the other which forces my head to turn to the right. Part of the reason I got this chair was for the headrest so it's a shame that i can't even use it with the headrest because it's uncomfortable.
I prefer the much more expensive chair provided by my employer but COVID19 has forced me to work at home. This chair fits my available space is comfortable works well and was super easy to assemble. Materials are passably sturdy the lean function is very nice.
My wife has some back problems and found this chair helped her feel better over an extended work times. She did first compare chairs at the store however. Assembly was fast easy and clearly explained.
