M57 Ergonomic Office Chair with 3 Way Armrests Lumbar Support and Adjustable Headrest High Back with Tilt Function (Black)

The Sihoo M57 offers great value with multiple adjustments (headrest, lumbar support, armrests, recline), comfortable mesh fabric, and a sturdy build. However, the recline tension knob's placement is inconvenient, especially with the footrest, and the armrests lack width adjustment. The warranty is only one year (though mechanical parts are covered for three).
