The Sihoo M57 is a mesh office chair with a headrest, adjustable lumbar support, 3D armrests, seat-height adjustment, and a recline that goes back to 126 degrees with adjustable tension. It holds up to 330 lbs and is BIFMA and SGS certified. It suits home-office and full-day desk workers who want broad adjustability without stepping up to a premium chair. Against rivals in its class, it offers more adjustments than many fixed-armrest mesh chairs, though the seat cushion and plastic build are where it shows its budget standing. Reviewers rate it highly for back support and breathability.
