A mesh office chair for buyers who want adjustable lumbar support, a retractable footrest, and flexible recline for work and breaks.
- Dual-back design with elastic adaptive lumbar support intended to move with changes in posture.

Pros
- Footrest and recline make it easy to create a more relaxed break position.
- The dual-back lumbar design is intended to accommodate changes in sitting posture.
Consider before buying

- If you prefer a padded seat surface, the B100 Pro’s full-mesh seat may not match that preference.
Read the full review summary
The B100 Pro combines a dual-back design that moves with posture changes with a retractable footrest and lockable recline.
That mix makes it worth considering if you want a chair that can shift between upright work and a more relaxed position without adding a separate footrest.
Its full-mesh seat and back, widened cushion, and wide headrest point toward buyers who value airflow and multiple adjustment options during desk time.
The tradeoff is a feature-rich design that prioritizes reclining and lounging as well as everyday work, so buyers who only need a basic upright chair may not use much of what it offers.
The buying factors
SIHOO B100 Pro Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support design
The dual-back arrangement is designed to move with the spine as the sitter leans forward, sits upright, or shifts position, which gives the chair a useful range for changing desk postures.
Recline and break flexibility
Lockable recline and a retractable footrest support a broader work-to-break routine than a fixed upright setup.
Armrest adjustability
The 4D armrests can be adjusted, rotated, or flipped, giving buyers several ways to position them around posture and desk clearance needs.
Airflow design
Mesh across both the back and seat is a practical choice for buyers who prefer an airy chair surface during long desk sessions.
Head and seat support features
A widened cushion and 3D wide headrest add support features for buyers who want more than a basic mesh seat and back.
Stated weight capacity
The chair is specified for support up to 300 lbs, a relevant fit check for buyers comparing chairs by stated capacity.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the SIHOO B100 Pro if you want an office chair that can move from focused desk work to reclined breaks.
The retractable footrest and lockable recline are its most distinctive practical features for a work area that also serves as a gaming or relaxation spot.
It is also a fit for buyers who want adjustable arm positioning and lumbar support designed around posture changes.
The headrest and widened cushion add to the support-oriented feature set, while mesh across the seat and back is suited to those who prefer an airy chair surface.
Who should skip it
Skip it if you want a simple upright chair and are unlikely to use a footrest or recline for breaks; those features are central to the B100 Pro’s flexible positioning.
Look elsewhere if you specifically want a chair with a padded rather than mesh seat surface.
SIHOO B100 Pro Review Analysis
Lumbar support for changing posture
The dual-back design is intended to move with the spine while the sitter leans forward, sits upright, or shifts position.
That makes the chair relevant to buyers who alternate between concentrated work and meetings, though individual fit will still depend on how the chair’s shape suits the person using it.
A chair that accommodates breaks
The retractable footrest and lockable recline broaden the chair’s use beyond a single upright desk position.
They make sense for a home office that also handles gaming or short rests, provided the buyer values reclining rather than wanting a strictly task-focused seat.
Mesh and adjustment choices
The mesh back and seat put airflow at the center of the chair’s design, while the 4D armrests allow more positioning choices around the user and desk.
Buyers should weigh that combination against their preference for a mesh seat and whether the wide headrest works with their posture.
Capacity and construction details
A reinforced metal base and Class 4 SGS-certified gas lift are paired with a stated capacity of up to 300 lbs.
Buyers who use weight capacity as a screening factor can check that figure against their needs before deciding.
