Read the full review summary
The B100 SE’s main appeal is the pairing of dynamic lumbar support with a thick, plush cushion.
Its lumbar support is intended to move with posture changes, while the softer seat may appeal to people who find traditional mesh seating too firm or exposed.
These design choices make it a comfort-focused desk chair rather than a bare-bones work seat.
It also offers adjustable seat height, an adjustable headrest, and three lockable recline angles, so buyers can tune the chair around their desk setup and preferred work or break posture.
The main tradeoff is that its cushioned seat differs from mesh seating, and fit will still depend on your body and desk; check the stated height range and recline positions against your needs before choosing.

Who Should Buy SIHOO B100 SE?
Good fit
Consider the B100 SE if you want a softer cushioned seat and lumbar support designed to move with posture changes. That combination is relevant for desk work that shifts between focused typing, meetings, and relaxed breaks.
It is also worth considering if you want a defined set of recline positions and a headrest that can support the neck while typing or leaning back.
Check that the 18.3-to-21.9-inch seat-height range fits your desk and preferred seating position.
Who should skip it
Skip it if you specifically want mesh seating: the B100 SE’s thick, plush cushion is positioned as a softer alternative to traditional mesh seats.
It may also be a poor fit if you need recline choices beyond its three lockable angles.
SIHOO B100 SE Review Analysis
Lumbar support for changing posture
The chair’s dynamic lumbar support is meant to follow the spine’s natural curve while the sitter leans forward, sits upright, or changes position.
That makes it a relevant feature for people who alternate between concentrated desk work and meetings, although individual comfort depends on fit and preference.
Cushioning versus mesh
The thick cushion and plush padding distinguish the B100 SE’s seat approach from traditional mesh. That may suit buyers seeking a softer, more padded surface, while those who prefer a mesh seat should weigh that preference carefully.
Recline and setup range
Seat height adjusts from 18.3 to 21.9 inches, and the headrest is adjustable.
The three lockable angles—110°, 125°, and 135°—provide distinct positions for working and relaxing; check the seat range and headrest placement against your desk and body before buying.
Standards and coverage
The chair is built to meet SGS and BIFMA standards and comes with 36-month coverage and 30-day easy returns.
These terms may make the purchase feel more supported, while the best choice still depends on whether the seat and adjustment range suit your everyday setup.

Is SIHOO B100 SE Worth It?
The SIHOO B100 SE is worth considering if your priorities are a plush cushioned seat, dynamic lumbar support, and three defined recline positions.
