Read the full review summary
The B100 is designed for desk workers who want lumbar support that moves with them and a mesh seat and back.
Its recline positions support a shift between focused work and relaxed breaks, while the wide headrest and widened cushion add support features for longer desk sessions.
The strongest fit is a home office where a chair needs to tuck beneath a desk between work sessions. The armrests flip up and adjust with the recline, and the chair supports up to 300 lbs.
Buyers seeking a place to stretch their legs during breaks should account for its no-footrest design.

Who Should Buy SIHOO B100 Chair?
Good fit
Choose the B100 if you want a mesh chair with adaptive lumbar support and several recline positions for switching between desk work and breaks.
Its armrests tuck under a desk, which can help keep a compact workspace clear when the chair is not in use.
It also suits buyers who prefer mesh across the seat and back and want a wide headrest and widened cushion. The up-to-300-lb support capacity is another relevant specification to weigh against your needs.
Who should skip it
Skip it if a footrest is central to how you want to relax in a chair. The B100 is specifically a no-footrest model, so recline alone will not provide a place to elevate or extend your legs.
SIHOO B100 Chair: Support and Workspace Fit
Lumbar movement for desk work
The B100’s adaptive lumbar support is designed to follow the natural curve of the back, with a dual-back construction intended to move as the sitter changes position.
That approach may appeal to people who shift between leaning forward and sitting upright, though the feature description cannot establish how the support will feel for a particular body or desk setup.
Recline for work and pauses
Three set recline angles give the B100 distinct positions for focused work and relaxed breaks.
Buyers who prefer a simple set of positions may find that useful; those who need a footrest for longer lounging should factor in the chair’s no-footrest design.
Mesh and compact desk clearance
The full-mesh design is intended to promote airflow, while the flip-up armrests can tuck under a desk.
That combination makes the chair a practical candidate for a workspace where ventilation and storing the chair close to the desk matter; the widened cushion adds another comfort-oriented design choice.
Capacity and ownership terms
The B100’s stated capacity is up to 300 lbs, and the chair is backed by a 3-year warranty and 30-day easy returns.
Those details can help buyers assess fit and purchase terms, but they do not replace checking that the chair’s dimensions and adjustment range work for the intended user.
