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.
Those features make it a candidate for buyers who want desk support alongside an option to stretch out during a break.
Its strongest fit is a home office, gaming area, or study setup where adjustability and reclining matter.
Buyers should weigh the recline and footrest features against their need for a particular seating feel, since the product information do not establish individual comfort or fit.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a mesh office chair with adaptive lumbar support and a footrest for breaks.
The dual-back design and retractable footrest address different parts of a workday: changing posture and stretching out between tasks.
It also fits buyers who value adjustable arm positioning and more than one recline angle for work, study, or gaming sessions.
Consider whether those features match your normal routine before paying for a chair with several ways to reposition.
Who should skip it
Skip it if you specifically want a padded seat, since this chair uses mesh across both the seat and back.
Buyers whose priority is a simpler fixed sitting setup may also have little use for the retractable footrest and multiple recline positions.
SIHOO B100 Pro Chair Analysis
Support that follows posture
The dual-back lumbar approach is the chair's central ergonomic feature. It is designed to move with the spine as the sitter leans forward or sits upright, a useful idea for people who vary their posture during desk work.
The feature description does not tell buyers how the support will feel for their body, so return terms and fit should factor into the purchase decision.
A chair with a break mode
The retractable footrest works with the lockable recline to give the chair a clear relaxation role in addition to desk seating.
That flexibility is most relevant when the same chair serves for work and downtime; buyers who rarely recline may not get much value from those features.
Mesh, headrest, and workspace fit
The mesh seat and back are presented as airflow-promoting, while the wide headrest and cushion add further contact points. These are design intentions rather than a guarantee of comfort for every user.
Check the chair's dimensions and confirm the fit with your desk and preferred sitting posture before ordering.

Choose the M18 if its seat-height, headrest, lumbar, and back adjustments meet your needs and its capacity suits you; choose the B100 Pro if a retractable footrest and four-dimensional armrests matter more to your setup.
- The M18 has adjustable seat height, headrest, lumbar support, and back support, with a mesh back and a capacity of up to 150kg.
- Its adjustment emphasis may suit buyers who want those controls and a headrest without prioritizing a footrest.
- The B100 Pro combines adaptive lumbar support with a retractable footrest and four-dimensional armrests, making it the more suitable fit for buyers who want repositioning options and a stretch-out feature in one chair.
Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering for a home office or gaming setup if you want adaptive lumbar support, adjustable recline, and a retractable footrest in a mesh chair.
Its combination of posture-related adjustment and break-time flexibility gives it a clear intended use.
Buy it when those features match how you work and relax, and when mesh seating fits your preference.
If you do not need reclining or a footrest, or prefer a padded chair, the B100 Pro's defining features may not justify choosing it.
