Read the full review summary
The B100 centers on a dual-back design with elastic lumbar support that follows the user's curve, plus three recline positions for changing posture between focused work and breaks.
The full-mesh construction, wide cushion and extra-wide 2D headrest round out a feature set aimed at everyday desk use.

The buying factors
SIHOO B100 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support
The dual-back construction and elastic dynamic lumbar support are designed to follow the user's natural curve while allowing movement, which makes this a strong fit for shoppers seeking built-in back support.
Recline flexibility
Three recline angles offer defined options for shifting between work and breaks, giving buyers useful posture flexibility without implying a fully reclining chair.
Desk fit
Armrests that flip up, adjust with recline and tuck beneath the desk make the chair practical to consider for compact workspaces.
Mesh construction
The full-mesh design is intended to promote airflow, a useful feature for people who spend long stretches at a desk.
Headrest and cushion
An extra-wide 2D headrest and widened cushion add support-focused features, though the provided specifications do not establish whether their dimensions suit every body type.
Capacity and warranty
A stated capacity of up to 300 lbs and a three-year warranty offer clear purchase parameters for buyers comparing fit and support coverage.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want a mesh chair with built-in lumbar support and multiple recline positions for alternating between desk work and breaks.
Its armrests fold up and tuck under the desk, which is especially useful when workspace clearance is tight.
It also makes sense for buyers who prefer mesh and want a defined capacity and warranty to check against their requirements. The chair supports up to 300 lbs and includes a three-year warranty with 30-day easy returns.
Who should skip it
Skip it if a footrest is essential: this is explicitly a chair without one. Buyers above the 300 lb capacity should also consider another chair.
SIHOO B100: Fit, Support and Recline
A support design for shifting posture
The B100's defining feature is its elastic lumbar support paired with a dual-back structure.
That layout is meant to follow the back's natural curve without restricting movement, while the three recline angles let users move from a work position to a more relaxed break.
Buyers who prefer a fixed upright feel should consider whether these adjustments match their routine.
Desk clearance and adjustment
The flip-up armrests are a practical part of the design: they adjust with recline and tuck under a desk.
This gives the B100 a useful space-saving angle for smaller work areas, while the headrest offers two-dimensional adjustment for positioning around the neck.
Mesh and everyday use
Full mesh is intended to keep air moving during long desk sessions, and the widened cushion is designed to spread weight more evenly.
These are relevant priorities for daily work, but shoppers should still check chair dimensions and fit for their own body and desk before committing.
Capacity and ownership terms
The 300 lb capacity helps define who should consider this model, and the three-year warranty plus 30-day easy returns provide the stated ownership terms.
The return period can be useful if the fit is uncertain, subject to the seller's applicable return process.

Consider the M18 if you want adjustable seat height and back support or need the capacity printed in its title; choose the B100 if its three recline angles and flip-up, tuck-under armrests better match your desk setup.
The capacity figures use different units, so compare them carefully against your needs.
- The M18 has adjustable seat height, headrest, lumbar and back support, and its title gives a 330 lbs capacity. Its notes also express capacity as up to 150kg.
- The B100 offers three recline angles and a 300 lb capacity, giving buyers a defined recline range and support limit to weigh when considering its flexible setup.
Is SIHOO B100 Worth It?
The SIHOO B100 Office Chair is worth considering if you want built-in adaptive lumbar support, three recline angles and armrests that fold out of the way beneath a desk.
The mesh design and widened cushion add practical features for everyday desk use.
Pass if you require a footrest or need capacity beyond 300 lbs.
For buyers within that limit who will use the recline and tuck-away arms, the B100's combination of adjustments and mesh construction makes it a reasonable office-chair option to shortlist.
