Read the full review summary
The B100 Pro combines elastic lumbar support that moves with the spine, a dual-back design and a retractable footrest.
Its four-dimensional armrests can adjust, rotate or flip up, while three recline positions support changes between desk work and breaks.
Consider it if you want a mesh seat and back, a wide headrest and a footrest in the same office chair.
The 300-pound support limit and 36-month coverage may also matter when comparing chairs, while the additional reclining and resting features make it a more elaborate fit than a chair used only for upright desk work.

Headrest support
The chair has a three-dimensional wide headrest designed to support the neck during seated tasks and breaks.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if your home-office routine includes both focused desk work and regular reclining breaks.
Its footrest, three recline positions and dual-back lumbar support are aimed at users who value ways to shift posture throughout the day.
It is also a candidate for buyers who want a full-mesh seat and back, adjustable armrests and a wide headrest in one chair. Check that the 300-pound support limit fits your requirements before buying.
Who should skip it
Skip it if a 300-pound support limit does not meet your needs, or if the chair's three fixed recline angles do not align with the adjustment range you want.
It may be more chair than you need if you want a straightforward seat for upright desk work and have little use for a footrest or reclining breaks.
SIHOO B100 Pro: Workday Support and Break-Time Flexibility
Lumbar support that moves with posture
The dual-back construction and elastic lumbar support are designed to move as you shift between leaning forward, sitting upright and changing position.
That makes the chair worth considering if you want lumbar support to be part of a more flexible seating setup, though the fit of any chair remains personal.
A chair with a built-in break mode
The retractable footrest is the feature that most clearly broadens this chair beyond desk posture: pull it out to stretch out, then use one of three recline angles for a change of position.
Buyers should consider whether they will use those break-oriented features often enough to make them worthwhile.
Mesh and headrest for extended desk sessions
A full-mesh seat and back promote airflow, and the wide headrest is designed to support the neck.
Together these features suit shoppers prioritizing breathable coverage and upper-body support, without guaranteeing that the chair will feel comfortable for every body or desk setup.
Check capacity and recline preferences
The support limit is up to 300 pounds, and the recline is set at three angles. Confirm the capacity and those positions suit your use before committing, particularly if you prefer more flexible recline adjustment.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want a mesh office chair that combines adaptive lumbar support with a retractable footrest, adjustable armrests and three recline positions.
Those features make it a stronger fit for a workday that includes planned reclined breaks than for a minimal upright-only setup.
Before buying, confirm that the up-to-300-pound support limit and the three recline angles suit your needs.
If they do, and you expect to use the footrest and posture adjustments, the B100 Pro offers a clear feature set for work and downtime in one chair.
