Read the full review summary
The B100 Pro combines a dual-back design intended to move with the spine, a mesh seat and back, and a retractable footrest.
That mix gives desk workers options for upright tasks and more relaxed breaks without requiring a separate lounge chair.
Consider it if lumbar adaptability, a wide headrest, and adjustable arms are priorities, and you want to recline between tasks.
Its 4D armrests and three recline positions offer flexibility, while the chair’s support limit and recline angles make it important to check fit and desk clearance before choosing it.
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 feature for people who shift between focused desk work and meetings.
Recline flexibility
Three lockable recline angles give buyers defined positions for focused sitting and breaks, though shoppers should consider whether the available angles match their preferred recline.
Armrest adjustment
The 4D arms rotate and flip up, allowing posture adjustments and the option to slide them under a desk when clearance is tight.
Break-time support
A retractable footrest expands the chair’s use for stretching out during short breaks, a practical extra for users who want more than an upright desk seat.
Breathable materials
Mesh covers both the back and seat, which promotes airflow during long work sessions; buyers who prefer padded upholstery may want a different seating feel.
Load capacity
The stated support limit is up to 300 lbs, so it gives a clear fit reference for shoppers assessing capacity needs.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a desk chair that can shift between upright work and reclined breaks.
Its adaptive lumbar design, three recline positions, and retractable footrest are most relevant to users who will make use of more than a basic seated posture.
It is also a candidate for buyers who prefer mesh surfaces and want armrests that can be repositioned or flipped out of the way. Check the chair’s measurements and capacity against your setup and needs before ordering.
Who should skip it
Skip it if you need a support capacity above 300 lbs or want a recline angle outside the three available positions. Those are concrete fit constraints to resolve before choosing this chair.
SIHOO B100 Pro: Workday Adjustability and Breaks
Lumbar movement for changing tasks
The dual-back lumbar structure is intended to follow the spine as the user leans forward, sits upright, or shifts position.
That design is aimed at varied desk postures; personal fit still depends on how the chair aligns with an individual’s back and sitting habits.
Recline and arm positioning
Three lockable angles create a straightforward choice between work and a more relaxed position.
The arms can rotate or flip up, and the latter may help when tucking close to a desk, provided the desk and chair dimensions work together.
Footrest and mesh tradeoffs
The pull-out footrest supports stretching out during a break, while the mesh seat and back promote airflow. Buyers who prioritize a traditional upholstered seat or rarely recline may not get as much value from these design choices.
