Read the full review summary
The B100 Pro combines a dual-back design with adaptive lumbar support, a retractable footrest and a full-mesh seat and back.
That mix suits a home office where the chair may also be used for reading, gaming or taking a reclined break.
Its standout appeal is adjustability: the armrests rotate or flip, and the recline locks at three angles.
Buyers who want a simpler upright work chair may find those relaxation features unnecessary, while anyone choosing it should make sure its recline and footrest fit the way they use a desk chair.
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 elastic lumbar support and dual-back construction are designed to move with posture changes, a useful fit for people who shift between leaning forward and sitting upright.
Recline flexibility
Three lockable recline positions give the chair a clear work-to-break range, although buyers who prefer a fixed upright posture may not use the extra settings.
Armrest adjustment
The armrests can be adjusted, rotated or flipped, helping accommodate different postures and allow the chair to slide under a desk.
Break-time support
A retractable footrest and wide headrest add practical support for stretching out and resting between desk sessions.
Breathable materials
Mesh covers both the back and seat, which is a useful design choice for buyers who value airflow during long desk sessions.
Stated weight capacity
The stated capacity is up to 300 lbs, with a reinforced metal base and Class 4 SGS-certified gas lift. Buyers should confirm that capacity suits their needs.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want one chair to cover desk work and reclined downtime. The footrest, lockable recline and wide headrest make stretching out between work sessions part of its design.
It is also a reasonable fit for buyers who prioritize airflow and adjustable arm placement. Mesh spans the seat and back, while the armrests can rotate or flip to accommodate posture and desk clearance.
Who should skip it
Skip it if you want a straightforward chair for upright work and do not expect to use a footrest or recline settings. Those features are central to the B100 Pro’s work-and-relaxation design.
If its stated capacity does not meet your needs, choose a chair with a capacity that does. The B100 Pro’s stated limit is up to 300 lbs.
SIHOO B100 Pro: Workday Support and Reclined Breaks
A dual-back approach to lumbar support
The chair pairs elastic lumbar support with a dual-back structure intended to move as you change position.
That design may suit people who alternate between leaning forward and sitting upright, though fit depends on individual posture and body shape.
Recline and footrest for downtime
The footrest extends for stretching out, and the recline offers three lockable angles. This makes the B100 Pro more oriented toward breaks at the desk than a chair focused only on remaining upright.
Mesh airflow and fit considerations
A full-mesh back and seat prioritize airflow, while a widened cushion and ultra-wide headrest shape the sitting area. Consider your body dimensions and desk arrangement, particularly if you prefer a compact seat or want armrests tucked close.
Capacity and construction
The chair combines a reinforced metal base with a Class 4 SGS-certified gas lift and a stated capacity up to 300 lbs. That gives buyers a concrete capacity figure to compare with their own requirements.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want a mesh office chair that combines adaptive lumbar support with reclined breaks.
Its retractable footrest, three recline positions and adjustable armrests give it a clear use case for buyers who alternate between working and relaxing at a desk.
Before buying, confirm the chair’s capacity and that its widened seat and ultra-wide headrest suit your body and desk.
If you need an upright-first chair or have no use for the footrest, its main features may not match your routine.
