Read the full review summary
The B100 Pro centers on posture adjustments and rest breaks: its dual-back design moves with the spine, the armrests adjust and flip, and the footrest pulls out for stretching.
That mix is useful if you want one chair to support desk time and occasional reclining without moving to a separate lounge seat.
Its full-mesh back and seat promote airflow, while the widened cushion and broad headrest add contact areas for longer sessions.
Consider it if those adjustments and the integrated footrest match your routine; the chair’s stated maximum supported weight is 300 lbs, so check that limit against your needs before buying.
The buying factors
SIHOO B100 Pro Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar adjustment
The dual-back lumbar support is described as moving with the spine, a useful fit for people who shift between forward-leaning and upright desk postures.
Recline flexibility
Three lockable recline angles provide options for focused sitting and breaks, though the seat remains an office chair rather than a dedicated recliner.
Armrest positioning
The 4D armrests can adjust, rotate, and flip, giving buyers more ways to position the arms or slide the chair under a desk.
Break-time support
A retractable footrest makes stretching out during a short break possible without adding a separate footrest.
Breathable seating design
Mesh covers both the back and seat to promote airflow, which may appeal to buyers who prefer a breathable chair surface.
Weight capacity
The stated maximum support is 300 lbs; buyers should confirm that this capacity fits their requirements.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a mesh chair with adjustable lumbar support and a footrest for stretching out during breaks.
The footrest, recline settings, and positionable armrests are especially relevant if you alternate between concentrated desk work and short periods of relaxation.
It also merits consideration if you prefer mesh across the seat and back and want a broad headrest as part of the chair.
Check the 300 lbs maximum against your requirements, and make sure the chair’s reclined position and extended footrest fit your room.
Who should skip it
Skip it if your required weight capacity exceeds 300 lbs; the stated maximum does not meet that need.
Look elsewhere if you need a chair that does not recline or include a footrest, or if your available space cannot accommodate the extended setup.
SIHOO B100 Pro: Workday Support and Reclining Tradeoffs
Support that moves with you
The adaptive lumbar system is the central ergonomic feature: the dual-back design is intended to follow changes between leaning forward and sitting upright.
This gives the chair a posture-oriented focus, though the right fit still depends on how its shape matches your body.
A chair that includes break mode
The retractable footrest and lockable recline make short rest periods part of the design.
They are useful additions for a home office that also serves as a gaming or leisure space, provided there is room to extend the chair.
Mesh and contact surfaces
Mesh covers both the seat and back, while the cushion is widened and the headrest is ultra-wide.
Those choices prioritize airflow and broader support surfaces; they do not guarantee comfort, so buyers should consider whether mesh seating and a wide headrest suit their preferences.
Capacity and room planning
The reinforced metal base and Class 4 SGS-certified gas lift are paired with a maximum support capacity of 300 lbs.
Plan around that limit and the space needed for reclining and footrest extension before making the chair your everyday workstation.
