This chair had the best lumbar support of all the chairs we tried. The assembly instructions were awesome. Never saw such detailed yet simple ones. Glad we bought this chair.
My stats: 42 years old 6'0" 285 lbs.... I found as I entered my late 30s I was starting to have back aches and needed a good lumbar support. Tried multiple chairs before finding this one it is just right for my back. The mesh material does start to lose its tightness after a couple years I'd say after having it for about 2.5 years I noticed it wasn't as firm as it should be anymore. I replaced it with the same chair 6 months later (now) so overall got about 3 years out of the thing. Keep in mind I work from home so spend easily 45-50 hours a week in the chair between work and personal use. To me that is an excellent wear and tear ratio given my weight and amount of usage. I would happily buy this chair every 3 years and not feel cheated. In fact I'm tempted to just buy another now as a spare and throw it in my basement for a few years from now as I find more often than not once I find something great the company inevitably stops selling it. :)
I have had the chair for about a month now and it is my favorite chair! it glides so nicely across my low pile carpet the back support is nice and firm (adjustable to your liking) and I can feel the fan through the mess so i don't get overheated! I have back problems so good support is great for productivity !
The chair is well constructed and functions as expected overall. My issue is that the arm supports are too high and the padding on them is too firm. I removed them and am using the chair without arm supports.
The chair is really nice and comfortable to sit in. Has a good brace for my back that can be adjusted arms raise & lower to height of your table. Really glad I brought this chair.
