- Full-mesh construction is designed to promote airflow, and the cushion is widened to spread weight more evenly.
Pros

Read the full review summary
The B100 combines a full-mesh design, an extra-wide headrest and elastic dynamic lumbar support intended to move with the sitter.
That makes it a plausible fit for everyday desk work when airflow, back support and the ability to shift posture are priorities.
Its practical appeal is strongest in a compact workspace: flip-up armrests tuck under a desk, while three recline angles support changes between focused work and breaks.
The widened cushion and up to 300 lbs capacity broaden its everyday-use case, though fit and comfort will still depend on the individual.
The buying factors
SIHOO B100 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Posture adjustment

Elastic dynamic lumbar support and a dual-back design are intended to follow the back's natural curve as the sitter moves.

Breathable construction
Full mesh is designed to keep air moving during long desk sessions, which may suit buyers who prefer a less enclosed chair surface.

Who Should Buy SIHOO B100?
Good fit
Consider the B100 if you want a mesh chair for daily desk work and value lumbar support designed to move with you.
Its full-mesh construction and widened cushion target extended work sessions, while the headrest adds another support point.
It also fits buyers who need to reclaim space beneath a desk or want recline choices built into the chair. The flip-up armrests tuck away, and the three positions accommodate shifts from work to a break.
Who should skip it
Look elsewhere if a footrest is essential, since the B100 is sold without one. Buyers who need a specific headrest fit should also check the 2D adjustment range against their preferences before settling on this chair.
SIHOO B100 Review Analysis
Support that moves with the sitter
The B100's defining support feature is an elastic lumbar system paired with a dual-back design.
Its intended movement may appeal to people who shift position while working, while buyers seeking a precisely positioned lumbar pad should decide whether a dynamic design matches their preference.
Recline choices for work and breaks
Three specified angles give the chair a more structured range of recline than a single tilt position.
They are positioned for moving between focused work and relaxed breaks, so the configuration may suit users who want posture changes without switching chairs.
A practical fit for tighter desks
The flip-up armrests are the clearest space-saving feature: they can tuck beneath a desk and also adjust with the recline.
That makes desk clearance a meaningful reason to consider the B100, particularly in a setup where a chair needs to move out of the way between sessions.
Mesh and everyday construction
Full mesh is intended to help air flow through the chair during long use, while the widened cushion spreads weight more evenly.
The reinforced frame, heavy-duty base and quiet casters round out the everyday office design, though those details do not establish an individual's comfort or fit.

Is SIHOO B100 Worth It?
The SIHOO B100 is worth considering if your priorities are adaptive lumbar support, a mesh build, selectable recline positions and armrests that clear space under a desk.
Its widened cushion, headrest and up to 300 lbs capacity add practical details for everyday office use.
It is a weaker match if you require a footrest, since this configuration comes without one.
