  • Our take on the B100 Pro Ergonomic Office Chair

    The Sihoo B100 Pro is a mesh-back ergonomic office chair built around adjustable lower-back support, 4D armrests that flip up, and a recline that stops at 135 degrees. Its headrest, lumbar pad and seat depth adjust, so it fits a wider range of bodies than fixed-frame chairs at the same tier. Buyers rate it very highly, and the common praise is the lumbar support and the armrest flexibility. The trade-offs are typical of mesh chairs: a firmer seat and assembly that takes some time.

    Questions and answers

    Is the B100 Pro good for lower-back pain?
    Its adjustable lumbar pad is the main feature and owners with back discomfort often credit it. It supports posture but is not a medical device.
    How far does it recline?
    The back reclines to 135 degrees and can lock at set positions. That is enough for a relaxed lean, not a full lie-flat rest.
    Do the armrests get out of the way?
    The 4D armrests flip up, so the chair can slide under a desk. They also adjust in height, depth and angle.
    Is the seat mesh or foam?
    The seat is mesh over a firm base rather than thick foam. It stays cooler but feels firmer than padded chairs.
    Does it come with a headrest?
    Yes, a headrest is part of the chair and adjusts. Shorter users may find its lowest setting still high.
    How hard is assembly?
    Most buyers manage it alone, but it takes time and the instructions are basic. Set aside an hour.
    Where is the B100 Pro Ergonomic Office Chair cheapest?
    At Official US Sihoo Store, for $299.99, as of our latest check.
