A mesh office chair for buyers who want adjustable lumbar support, flexible armrests, and a retractable footrest for work and breaks.
- Adaptive elastic lumbar support with a dual-back design.
- Retractable footrest for stretching out during breaks.
- Four-dimensional armrests that adjust, rotate, or flip.
- Three recline angles: 110°, 125°, and 135°.
Pros
- Retractable footrest adds a dedicated option for reclining breaks.
- Armrests offer several ways to adjust their position.
Consider before buying

- The recline positions are set at three specified angles, so buyers seeking a different preferred angle should check whether one of them works for their routine.
Read the full review summary
The B100 Pro combines a full-mesh seat and back with an adaptive dual-back lumbar design, a retractable footrest, and armrests that adjust, rotate, or flip.
That mix makes it a plausible choice for a home office where the chair needs to handle focused desk time as well as occasional reclining breaks.
Its strongest fit is for someone who values configuration options and a footrest in one chair.
The tradeoff is that the central comfort features are adjustable by design, so buyers should consider whether the seat shape, recline positions, and support style suit their own body and desk setup.
The buying factors
SIHOO B100 Pro Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Adjustable lumbar support
The elastic dual-back design is intended to move with changing seated positions, which gives buyers a support feature aimed at active desk use.
Recline flexibility
Three lockable angles give the chair distinct positions for upright work and reclined breaks.
Armrest adjustment
The armrests can adjust, rotate, or flip, making it easier to adapt their position around posture changes or desk clearance.
Rest features
A retractable footrest and wide headrest make this chair more oriented toward taking breaks at the desk as well as working.
Breathable mesh design
Mesh covers both the back and seat, a useful design choice for buyers who prefer airflow through the chair during desk sessions.
Capacity and base
The reinforced metal base and stated 300 lbs capacity provide a clear load specification for buyers checking fit against their requirements.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a desk chair with a retractable footrest for switching from work to a reclined break.
Its mesh seat and back, wide headrest, and widened cushion also make it a fit to consider if you want those comfort-oriented features together.
It is also worth considering if flexible arm positioning matters at your desk. The armrests adjust, rotate, and flip, while the three recline angles give you defined options for changing posture during the day.
Who should skip it
Skip it if you need a chair with a specific recline position outside its three available angles. The B100 Pro’s recline choices are 110°, 125°, and 135°, so confirm that range matches how you prefer to sit.
Look elsewhere if you specifically want to avoid a dual-back lumbar design or do not want a footrest as part of your chair setup.
SIHOO B100 Pro Review Analysis
Support for changing positions
The elastic dual-back lumbar setup is designed to move with the spine as the sitter changes posture.
That makes the chair worth considering for people who alternate between leaning forward and sitting upright, though personal fit will depend on whether this support style feels appropriate at the desk.
A work chair with a break mode
A pull-out footrest and recline positions turn the chair toward relaxation as well as desk work.
The practical appeal is having those options at the workstation; buyers should still verify that their desk and available floor space leave room to extend and use the footrest.
Desk fit and adjustment
The armrests can be adjusted, rotated, or flipped to suit posture or slide beneath a desk.
That flexibility can help in a changing workspace, while the widened cushion and ultra-wide headrest shape the chair’s fit; check dimensions and clearance against your own desk and body before buying.
Structure and everyday use
The chair pairs a reinforced metal base with a Class 4 SGS-certified gas lift and a capacity of up to 300 lbs.
Quiet casters and smooth tilt control are intended for easier movement and adjustment, while the stated coverage period may matter to buyers weighing long-term ownership.
