Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a chair that can move between upright work and reclined breaks. The three lockable angles, adaptive dual-back lumbar support, and retractable footrest address those uses directly.
It also suits buyers who value adjustable arm positioning and a mesh seat and back. The widened cushion and ultra-wide headrest add further contact points for desk sessions, while the support limit is up to 300 lbs.
Who should skip it
Skip it if you need a chair rated above 300 lbs; the stated capacity may not fit that requirement.
It may also be a poor match if you specifically want a conventional cushioned seat, since this model uses mesh for both the seat and back.
SIHOO B100 Pro: Workday Support and Reclined Breaks
Adaptive support for changing posture
The dual-back arrangement is intended to move with the spine as the sitter leans forward, sits upright, or changes position.
That makes the lumbar design relevant to people whose desk routine includes more than one static posture, though fit remains personal.
Recline and footrest as a pair
The footrest gives the recline function a clear break-time use: extend it to stretch out, then return to a working position as needed.
The three angles allow a choice of recline, but buyers should make sure their room has enough clearance to use the footrest.
Mesh, cushion, and headrest
Full mesh is a practical choice for shoppers who prioritize airflow across the chair's seat and back.
The widened cushion and 3D ultra-wide headrest add shaping and neck support to the design, but these features do not establish that the chair will suit every body or desk setup.
Fit and daily-use checks
The 300 lb support limit is a clear threshold to check before ordering. Buyers should also measure desk clearance and available floor space, especially if they plan to flip the armrests up or extend the footrest during breaks.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want adaptive lumbar support, several recline positions, adjustable armrests, and a retractable footrest in one mesh office chair.
Those features make it particularly suited to desk workers who also want a place to stretch out during breaks.
Before buying, check the 300 lb capacity and make sure a full-mesh seat suits your preference. If both fit, the B100 Pro's support and recline features offer a coherent setup for work and off-duty sitting.
