Read the full review summary
The B100 Pro suits a home office where the chair needs to shift between focused desk work and reclined breaks.
Its dual-back design provides adaptive lumbar support, while the footrest and lockable recline give you more ways to change posture over the day.
It is also a practical fit for shoppers who prioritize breathable mesh, a wide headrest and armrests that can move out of the way under a desk.
The feature set leans toward adjustability and relaxation, so consider whether those options justify choosing a chair with a more involved setup than a basic task seat.
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
The dual-back arrangement is designed to move with posture changes, making adaptive lower-back support central to the chair’s appeal.
Recline flexibility
Lockable recline with three selectable angles gives the chair a defined range from upright work to leaning back.
Armrest adjustability
The armrests rotate and flip as well as adjust, offering several ways to align them with posture or desk clearance.
Break-time support
A retractable footrest adds a leg-stretching option for breaks without leaving the chair.
Breathable seating
Mesh covers both the back and seat, supporting airflow across more of the chair than a mesh back alone.
Capacity and build details
A reinforced metal base and Class 4 SGS-certified gas lift accompany a stated 300 lb capacity, useful points to check against your requirements.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want one chair for desk work and reclined breaks. The footrest, lockable recline and adjustable armrests offer multiple ways to change posture without moving away from the workstation.
It also fits shoppers who prefer mesh seating and want lumbar adjustment paired with a broad headrest. Check the 300 lb capacity against your needs, and make sure the available chair adjustments suit your desk layout.
Who should skip it
Skip it if you need a chair strictly for upright task work and have no use for a footrest or reclining breaks; those features are a prominent part of this design.
Look elsewhere if the stated 300 lb capacity does not match your requirements.
SIHOO B100 Pro: Support and Recline in Daily Use
Adaptive support through posture changes
The dual-back lumbar design is intended to move as you lean forward, sit upright or shift position.
That makes adjustability the defining choice here: buyers should plan to tune the chair to their desk posture rather than expect a single fixed seating position to suit every task.
A work chair that reclines for breaks
Three recline angles and a retractable footrest make relaxation part of the chair’s intended role.
The tradeoff is that these features matter most when you have room to lean back and use the footrest; in a crowded or tightly positioned workstation, that flexibility may be less useful.
Mesh, headrest and desk fit
Full-mesh construction supports airflow, while the wide headrest and widened cushion add contact-area features for longer sitting sessions.
Armrests that flip and rotate can help with desk fit, but buyers should consider how those moving parts line up with their own workspace before choosing.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want adaptive lumbar support, mesh seating and a chair that can shift from desk work to reclined breaks.
Its footrest, three recline angles and adjustable armrests give it a broad set of posture options for a home office.
Buy it when you will use those reclining and stretching features, and when its stated capacity of up to 300 lbs fits your requirements.
If you mainly need a straightforward upright desk chair, the extra adjustment and lounge-oriented features may not add enough value for your routine.
