Read the full review summary
The B100 Pro combines a dual-back design with adaptive lumbar support, four-dimensional armrests, and three recline angles.
That range of adjustment suits buyers who change posture through a workday and want the option to lean back for a break.
The full-mesh seat and back are intended to promote airflow, while the widened cushion and wide 3D headrest provide additional contact and adjustment points.
This is a feature-rich option for a home office that also serves as a gaming or study space; the footrest makes reclined breaks part of its design.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want one chair for desk work and reclined breaks. The retractable footrest, three recline angles, and adjustable armrests support that mixed-use setup.
It also suits buyers who prioritize airflow-oriented materials and a broad set of support adjustments. Check that the stated capacity of up to 300 lbs aligns with your requirements.
Who should skip it
Skip it if you want a simple chair for upright desk work and have no use for a footrest or reclining breaks; those features are central to this design.
Look elsewhere if your needs exceed the chair’s stated capacity of up to 300 lbs.
SIHOO B100 Pro: How Its Adjustments Shape the Workday
Support that moves with posture
The dual-back arrangement and elastic lumbar support are aimed at adapting as you lean forward, sit upright, or shift position. The practical appeal is flexibility during a changing workday, rather than a fixed lumbar setup.
A chair that also serves for breaks
The retractable footrest pairs with the recline function for stretching out between tasks. Buyers who intend to use the chair only upright may get less value from this part of the design.
Desk fit and positioning
The armrests adjust, rotate, and flip, which helps tailor their position and slide the chair under a desk. The wide headrest and widened cushion are also worth considering in relation to your desk layout and preferred fit.
Materials and capacity
Mesh across the seat and back is intended to promote airflow, and the reinforced metal base and Class 4 gas lift provide a stated support capacity up to 300 lbs.
Buyers should use that capacity as a firm selection check for their situation.
