Read the full review summary
The B100 is worth considering if your desk chair needs to shift between focused sitting and reclined breaks.
Its dual-back arrangement is designed to move with the spine, while a wide headrest, widened cushion, and full-mesh construction address support and airflow across a workday.
It best suits people who want adjustable recline and armrests that can clear a compact desk.
The chair is rated to support up to 300 lbs and comes with a three-year warranty; buyers seeking a footrest should look elsewhere, since this B100 is sold as a chair without one.
The buying factors
SIHOO B100 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support design
The elastic dual-back lumbar support is intended to follow the natural curve and move with the sitter, a useful feature for buyers who change posture during desk work.
Recline flexibility
Three recline angles give the chair distinct positions for focused work and relaxed breaks, offering more than a single fixed posture.
Desk clearance
The armrests flip up and tuck under a desk, which is handy when floor or desk space is tight.
Airflow design
A full-mesh design is aimed at keeping air moving during long periods of sitting, a practical choice for buyers who prefer mesh seating.
Head and seat support
The extra-wide headrest and widened cushion target neck support and weight distribution, though individual fit will depend on the sitter and desk setup.
Warranty coverage
A three-year warranty and 30-day returns provide defined support terms for buyers considering a daily-use chair.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want a mesh chair whose back support is designed to move with you as you change posture.
The three recline angles make it a candidate for alternating between focused work and breaks without needing a separate lounge chair.
It also fits compact desk arrangements where armrests need to clear the desktop. Flip-up arms, a wide headrest, and a widened cushion make the B100 most relevant to buyers prioritizing adjustable posture support and practical desk fit.
The up-to-300-lb support rating and three-year warranty may matter to buyers comparing chairs for regular home-office use. Confirm the chair fits your proportions and setup, since headrest and cushion comfort are personal.
Who should skip it
Skip it if a footrest is essential for stretching out during breaks; this B100 is explicitly a no-footrest design.
Look elsewhere if you need recline control beyond the three provided angles, or if you prefer to avoid mesh as your main chair material.
SIHOO B100 Review Analysis
Adaptive lumbar support for changing posture
The B100’s dual-back support is designed to follow your natural curve as you move, with lumbar support that does not restrict movement.
That may appeal if you shift between working positions, though it is a support design rather than a guarantee of personal comfort.
Recline and desk fit
The three-angle recline gives a defined set of positions, and the armrests can move up and tuck beneath a desk.
That combination is useful when the chair needs to serve both work and short breaks while returning to a compact footprint afterward.
Mesh, cushion, and headrest fit
The full-mesh build aims to keep air flowing, while the widened cushion is intended to spread weight more evenly.
The extra-wide 2D headrest adds neck support, but chair fit remains personal, so buyers should consider their own proportions and desk height.
