I have purchased 4 chairs like this. This one has plastic pieces protruding in the seat that are very uncomfortable One of the them the seat is parting from the frame. The other 2 are comfortable and working fine.
all ajustments are manual you have to get out of the chair and turn it over. Also it's chair is not 17 inches deep it's about 21". I'm about 125 lbs and the mesh stretches to hit the support bar. The back support only hits on one angle so feels like another bar. The 3 stars is because it is actually a chair and looks ok.
I love this chair so much this is the second time I bought it! I left the first one at my old office and spent one day in the chair that was here before ordering this one. Very comfortable cool and great lumbar support!
This chair is exactly what I was looking for. The mesh is very comfortable definitely not hot to sit in and the ergonomics are just what I needed. The plus was that it was on sale as well.
