Have had it a little over a week now and very happy with the purchase so far. Was pretty easy to put together and have been working 10 hour days in it without any issue.
We have only been using this chair for about 2 weeks but it is already so creamy we are thinking about returning it. Our weight is normal and the chairs seems not to be able to handle the 140 ponds. Very disappointing.
The back and flat of the char is flexible but firm mesh which is comfortable and does not flatten over time leaving you with sitting on a flat metal plate. Overall it’s a great buy.
I really wanted to like this chair as I've always wanted a mesh chair for improved ventilation which this does well. That said due to it being a mesh chair you have to fit in it perfectly for it to be comfortable. The mesh stretched between hard plastic components so if you are a little bigger than normal (I'm 6'4" and 250 pounds) you end up feeling the hard plastic supports. I actually started putting my wallet in my front pocket hoping I'd be comfortable for longer than 10 minutes (on the plus side I am getting up from the computer much more often now so I guess there is a health aspect to it). I would have given it one star due to my disappointment but the chair is well-made and likely comfortable for normal-sized people so I gave it three stars. I have two more weeks to return it and keep hoping it will magically become more comfortable but I have my doubts.
