Read the full review summary
The SIHOO B100 Pro is built around movement and posture adjustments: its dual-back lumbar support moves with the spine, while the armrests can adjust, rotate or flip.
A retractable footrest and lockable recline extend the chair's use from focused desk work to short relaxation breaks.
It is aimed at home-office users, gamers and students who value a breathable mesh seat and back, multiple recline positions and a broad headrest.
The chair has a stated support limit of 300 lbs and a reinforced metal base, but its extra reclining and footrest features make it a larger set of priorities than a simple task chair.

Who Should Buy SIHOO B100 Pro?
Good fit
Buy the SIHOO B100 Pro if you want a work chair that can recline for breaks and includes a retractable footrest.
Its lumbar design and adjustable armrests also suit users who change position or like to tune how their arms rest at the desk.
It may fit home offices or gaming spaces where mesh, a broad headrest and multiple recline positions are appealing.
Check the 300 lbs support limit along with chair dimensions and desk clearance, especially if you expect to use the footrest or flip the armrests under the desk.
Who should skip it
Skip it if you want a minimal chair with few adjustment parts or do not expect to use a footrest or recline. Those features are central to the B100 Pro's sit-and-relax design.
Look elsewhere if the 300 lbs support limit does not leave a suitable margin for your needs.
SIHOO B100 Pro: How Its Recline and Support Fit Desk Work
A moving lumbar design
The dual-back system is intended to follow the spine as the sitter leans forward, sits upright or shifts during the day.
That makes the chair worth considering for people who dislike staying in one fixed position, though the fit of any lumbar support depends on how it aligns with an individual's back.
Recline and footrest for breaks
The chair combines lockable recline at three angles with a retractable footrest, so the same seat can serve focused work and a more extended break.
Buyers who mainly sit upright may get less value from this extra flexibility, while those who like to lean back have a clear feature to prioritize.
Mesh and upper-body support
The full-mesh back and seat promote airflow, and the 3D ultra-wide headrest supports your neck. Headrest fit is personal, so check the chair's dimensions and whether its shape suits your posture before committing to a long-session setup.
Fit and desk clearance
The armrests can flip or slide under a desk, which offers some flexibility for storage and positioning. Before buying, compare the chair's footprint and support limit with your workspace and intended use; the stated capacity is 300 lbs.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want an ergonomic mesh office chair with adaptive lumbar support, flexible armrests and a footrest for reclining breaks.
Its most distinctive buying case is the combination of posture adjustment and lounge-style features in one chair.
It is a less compelling fit if you want a simple upright chair, and the 300 lbs support limit should factor into the decision.
Confirm the chair's dimensions and how its headrest and lumbar support align with your body and desk before choosing it for a full-time setup.
