I love the mesh on the back and bottom I apparently produce a lot of heat while sitting in the old style office chairs. Love all the cushioning but I get hot and uncomfortable rather quickly. This type of chair lets me breathe and stay cool. The mesh is supportive in the seat as well I'm comfortable thats all that matters for me.
The head restscrew holes would not align with the back screw holes. Had to shave some of the head rest bracket to align them. They must have poor quality control. The chair is ok as an office chair.
