Pros
- Adaptive dual-back lumbar support is designed to move with posture changes.
- The retractable footrest adds a way to stretch out without leaving the chair.

- The chair's many adjustments may be unnecessary if you want a simple, fixed-position task chair.
Read the full review summary
The B100 Pro combines an adaptive dual-back lumbar design with a full-mesh seat and back, a wide headrest and a retractable footrest.
That mix makes it worth considering if your home office chair needs to support focused desk sessions as well as occasional reclining breaks.
Its defining appeal is range of adjustment: the armrests rotate and flip, and the recline locks at three angles.
Consider it if you value those positioning options and the chance to put your feet up; its feature set is more involved than a basic task chair, so prioritize the adjustments you will actually use.

Who Should Buy B100 Pro Chair?
Good fit
Choose the B100 Pro if lumbar support that moves with posture, a retractable footrest and multiple recline positions match how you work and take breaks.
Those features make it suited to a home office where the chair may also be used for reading or gaming.
It is also a plausible fit for buyers who prefer a mesh chair and want the seat and back to promote airflow.
Check that the stated capacity suits the intended user and that the chair's recline and footrest will fit the available area.
Who should skip it
Skip it if you want a simple chair without reclining or a footrest; those features are central to the B100 Pro's work-and-break design.
Look elsewhere if the stated support capacity does not match your needs, or if you prefer a non-mesh seat and back.
B100 Pro Chair: How Its Work and Break Features Fit
Lumbar support through position changes
The dual-back construction is intended to move with the spine, which could suit desk users who alternate between leaning forward and sitting more upright.
It is a design feature rather than a guarantee that the support will suit every body; if lumbar fit is a priority, check the chair's adjustment and return terms before deciding.
Recline and footrest for breaks
The three locking recline angles and pull-out footrest point to a chair meant to cover brief relaxation as well as upright desk work. Make sure your floor plan leaves room to extend the footrest and lean back comfortably.
Mesh, cushioning and head support
The full-mesh seat and back emphasize airflow, while the widened cushion and wide headrest add support surfaces for longer desk sessions.
Material preference is personal, so buyers who prefer upholstered padding should consider whether a mesh surface suits them.
Construction and ownership terms
A reinforced metal base and Class 4 SGS-certified gas lift accompany a stated support capacity of up to 300 lbs.
The package also includes 36-month coverage and 30-day returns, giving buyers a period to assess whether the chair's fit and adjustments work for their setup.

Choose the B100 Pro if a retractable footrest and four-dimensional armrests are priorities; prefer the M18 if you want adjustable seat height, headrest, lumbar and back support and its capacity of up to 150kg suits your needs.
- The M18 has adjustable seat height, headrest, lumbar and back support, plus a stated capacity of up to 150kg.
- The B100 Pro is centered on an adaptive dual-back lumbar design and adds a retractable footrest and four-dimensional armrests for more ways to recline and reposition.
Is B100 Pro Chair 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 locking recline positions.
Its feature mix is particularly relevant when a chair also needs to work for short relaxation breaks.
Buy it if those adjustments match your routine, the up-to-300-lb capacity fits, and your workspace can accommodate reclining and the footrest.
If you do not need the break-time hardware or prefer a simpler seat, the B100 Pro's extra functions are unlikely to be useful day to day.
