Read the full review summary
The B100’s elastic lumbar support uses a dual-back design intended to follow the spine as the user moves.
Three recline angles allow a shift from focused work to a more relaxed position, while the extra-wide 2D headrest and flip-up armrests add adjustability around the upper body and desk setup.
A full-mesh design promotes airflow, and the widened cushion is intended to spread weight more evenly.

Who Should Buy SIHOO B100 Chair?
Good fit
Consider the B100 if you want lumbar support designed to flex with movement and more than one recline position for work and rest breaks.
The wide headrest and flip-up armrests offer useful adjustment around the upper body and desk.
It may also fit a compact desk area: the armrests flip up and tuck under the desk, and the full-mesh design is intended to keep air flowing during longer work periods.
Who should skip it
Skip this model if a built-in footrest is central to how you plan to relax or work; this B100 is specified without one.
Look elsewhere if the stated 300 lbs capacity does not match your requirements, or if you need a chair whose fit can be confirmed against a specific body size before purchase.
SIHOO B100 Chair Performance and Fit
Support that follows movement
The elastic lumbar support and dual-back design aim to follow the user’s natural curve, which could appeal to people who change posture during desk work.
Buyers who need a particular lumbar shape or firmness should confirm that this style suits their preference before settling on it.
Recline for work and breaks
Three recline angles create a choice between a more upright working position and a deeper lean for breaks.
This is a practical range for buyers who want position changes, while the source does not establish a lock mechanism or a particular recline feel.
Desk space and arm placement
Flip-up armrests can tuck beneath the desk and adjust with recline, which may help when space is tight or when arm position changes during the day. Check the desk clearance and armrest height against your setup before ordering.
Mesh, cushion, and practical limits
The full-mesh construction promotes airflow, and the widened cushion is designed to spread weight more evenly. At up to 300 lbs capacity and with no footrest, its fit is clearest for users whose needs align with those limits.
