A widened cushion and extra-wide headrest provide useful contact-area features, though comfort depends on personal fit and preference.

Who Should Buy SIHOO B100?
Good fit
Consider the B100 if lumbar support that moves with posture is a priority.
The dual-back design and elastic support are intended to follow the natural curve, while three recline angles let you change position between focused work and breaks.
It also fits buyers working in tighter desk areas: the armrests flip up and tuck beneath the desk, and the full-mesh design promotes airflow. The widened cushion and extra-wide headrest round out its desk-focused support features.
Who should skip it
Look elsewhere if a built-in footrest is central to your break routine; the B100 is explicitly a chair without one. Its three recline positions may also be limiting if you prefer more open-ended recline adjustment.
SIHOO B100: What Its Support Design Means at a Desk
A moving lumbar approach
The dual-back structure is intended to follow the body's natural curve rather than hold the back in one rigid position. That design may suit buyers who shift posture throughout the day, though chair fit remains personal.
Recline for work and pauses
The three fixed angles give a choice between a more upright work posture and a more relaxed break position.
Think about whether these discrete options match how you sit, especially if you like to make small adjustments throughout a task.
Mesh and cushioning priorities
Full mesh promotes airflow, while the widened cushion is intended to spread weight more evenly. Those features address different comfort preferences, so consider whether you value an airy surface and broad seat area in your daily setup.
Practical fit around a desk
Flip-up armrests that tuck beneath a desk can help when floor space is tight or the chair needs to slide out of the way.
The no-footrest configuration keeps the B100 focused on desk seating rather than lounge-style leg support.
