The chair in the store was comfortable and just my size; try one first. I am 5'11 and 205lb. If you're a bigger in the middle other chairs are wider. Union and Scale made a chair that is solid and easy for most folks to put together. There is a lot of twisting with the Allen wrench but that is the most difficult work. Everything is CLEARLY explained and the screws are color coded in separate packets. So open one packet at a time for easy install. Very happy I spent the money. I bought it 1/2 off on Pres Day sale.
The color of this chair is a beautiful deep red. I wasn't sure about the mesh at first because I have never had a chair with a mesh seat but it really is quite comfortable to sit in all day long. Other chairs I always have to move around it and sit differently. This one holds me well and still has flex so it doesn't feel like you're sitting on a rigid surface the whole time.
