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.
This chair is super comfortable I used to have back pains from my previous chair and this has completely solved that issue. My only issue after having this chair for a few months is the creaking. it has massive amounts of creaking when I lean back just a little bit but stops after I keep leaning farther. Other than that this is a perfect chair.
I bought this for my telecommuting home office very comfortable after week 1 Seems sturdier and better ergonomically than the similar model I had purchased previously at Costco.
