Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want lumbar support designed to move with your back, plus multiple recline angles for shifting between concentrated work and breaks.
It is a practical fit for a compact desk area: the armrests flip up and tuck beneath the desk, while full mesh and a widened cushion suit everyday desk use.
Consider it if its up-to-300-lb capacity, 2D headrest and three-year warranty align with your requirements.
Who should skip it
Skip it if a footrest is essential for stretching out during breaks; the B100 is designed without one.
Look elsewhere if the chair’s stated 300-lb capacity does not meet your needs.
SIHOO B100 Review Analysis
Adaptive support for desk work
The B100’s dual-back construction is intended to follow the natural curve while allowing movement.
That makes adaptive lumbar support its central fit point for people who shift posture at a desk, though individual fit depends on body shape and setup.
Recline and armrest flexibility
Three recline angles let the chair move from focused work toward a more relaxed position. Because the armrests adjust with recline and flip up, the design also accommodates desks where arm clearance is useful.
Mesh, cushion and headrest
Full mesh encourages airflow, while the widened cushion is intended to spread weight more evenly. The 2D headrest adds neck support; buyers should still check fit against their desk routine and preferred sitting position.
Build and after-sale terms
The chair has a reinforced frame and heavy-duty base, and its capacity is up to 300 lbs. SGS and BIFMA standards testing, plus a three-year warranty and 30-day returns, give buyers concrete product and support details to weigh.

- The B100 Pro adds a retractable footrest, 4D armrests and a 3D wide headrest, and retains three recline angles.

Is SIHOO B100 Worth It?
The SIHOO B100 is worth considering if you want adaptive lumbar support, recline flexibility and armrests that can tuck beneath a desk.
Mesh construction, a widened cushion and the adjustable headrest round out a feature set aimed at everyday home-office use.
Its key tradeoff is the lack of a footrest, and buyers should match the 300-lb capacity to their needs.
If those limits work for your setup, the adjustable support and desk-friendly armrests make the B100 a considered option for routine desk work.
