Steelcase Gesture

Choose the Gesture if your arms are the problem. Its arms swing through a full 360 degrees and, by Steelcase's account, have the widest width range of any chair on the market, so they can be set close for typing or swung out wide. Broad-shouldered sitters who find most armrests pinch should start here. The controls are refreshingly simple: a front knob sets seat height and depth, a back knob sets tension and recline stop. Lower-back support is built into the back, but adjustable lumbar is an option, so add it if you want to fine-tune it. It is rated to 400 lbs and has a 12-year multi-shift warranty.
