Read the full review summary
The B100 SE centers its appeal on a thick, plush seat and lumbar support that moves with changes in posture.
That combination makes it worth considering for a home office where a softer seat and ongoing lower-back support matter during desk work.
Its adjustable seat height, adjustable headrest and three lockable recline positions add ways to adapt the chair for a desk, calls or a break.
Buyers who need a chair whose fit can be tuned should compare the listed adjustment range with their own desk and preferred posture before choosing.
The buying factors
SIHOO B100 SE Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support
Dynamic support follows the spine’s natural curve as the user shifts between leaning forward, sitting upright and changing posture.
Seat cushioning
The thick, plush cushion is a clear fit for shoppers who prefer padded seating to a traditional mesh seat.
Fit adjustments
Seat height spans 18.3 to 21.9 inches, and an adjustable headrest provides another fit option for the neck.
Recline flexibility
Three lockable angles provide distinct work and rest postures, though the chair’s listed recline positions are specific rather than continuous.
Build and support terms
The chair is built to meet SGS and BIFMA standards and includes 36-month coverage and 30-day returns, useful terms for a substantial home-office purchase.

Who Should Buy SIHOO B100 SE?
Good fit
Consider the B100 SE if a plush, thick cushion is a priority and you want lumbar support that follows posture changes through desk work.
Its headrest and adjustable seat height also offer several fit controls to evaluate against your own setup.
It is also a candidate for buyers who want a small set of defined recline positions for shifting from focused work to a more relaxed posture.
The SGS and BIFMA standards, 36-month coverage and 30-day returns add practical purchase considerations.
Who should skip it
Skip this chair if you specifically want a traditional mesh seat; the B100 SE is built around thick plush cushioning for a softer sitting experience.
Buyers who need a mesh back should look for a chair whose seat and back materials match that preference.
Look elsewhere if the chair’s specified three lockable angles do not offer the recline choices you need, or if its seat-height range does not fit your desk setup.
SIHOO B100 SE Office Chair Analysis
Support that moves with posture
The dynamic lumbar design is meant to follow the spine’s natural curve while the user leans forward, sits upright or changes posture.
This makes the chair a plausible option for varied desk tasks, though individual fit still depends on whether the support lands comfortably for the buyer.
A padded alternative to mesh seating
The B100 SE uses a thick cushion with plush padding and is positioned for a softer seat feel than traditional mesh seats.
That will appeal most to buyers who prefer cushioning; shoppers who prioritize mesh seating should weigh this design choice carefully.
Fit and recline choices
The seat height adjusts from 18.3 to 21.9 inches, while the headrest adjusts to support the neck during typing, calls or leaning back.
Three lockable angles—110, 125 and 135 degrees—provide defined recline options, so compare those positions with the way you plan to use the chair.
Coverage and daily-use considerations
The chair is built to meet SGS and BIFMA standards and comes with 36-month coverage plus 30-day easy returns.
Those terms add reassurance around the purchase, while checking seat-height fit and the specific recline positions remains important for choosing an office chair that matches your routine.

Its main appeal is the combination of plush cushioning and defined adjustment options.
