The SIHOO B100 suits desk workers seeking adaptive lumbar support, breathable mesh, and recline options, with a design that leaves out a footrest.
- Elastic dynamic lumbar support uses a dual-back design intended to follow the user's natural curve.

- Extra-wide 2D headrest and flip-up armrests that tuck under a desk.
- Full-mesh design and widened cushion.
Pros
- Adaptive lumbar support is designed to move with the back.
- Multiple recline angles accommodate shifts between focused work and breaks.
Consider before buying
- A footrest is not included, so it is a less direct fit for buyers who want to stretch out with their legs supported.
- For long sessions, consider whether a widened cushion and an extra-wide headrest match your preferred seat and neck support; individual fit can vary.
Read the full review summary
The B100 combines a dual-back design with elastic dynamic lumbar support intended to follow the user's curve.
Its full-mesh construction, widened cushion, extra-wide 2D headrest, and three recline angles give desk workers several ways to configure the chair for focused work and breaks.
Its strongest fit is a home or work desk where armrests need to tuck under the desktop and airflow is a priority.
The chair supports up to 300 lbs and comes with a 3-year warranty, but the title identifies it as a no-footrest model, so buyers wanting an integrated place to stretch their legs should look elsewhere.
The buying factors
SIHOO B100 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support
The elastic dynamic support and dual-back design are intended to move with the user's back, a useful feature for changing positions during desk work.
Adjustability
Three recline angles and flip-up armrests offer practical ways to shift posture and clear desk space.
Breathable construction
Full-mesh construction is designed to keep air flowing through long work sessions.
Headrest
The extra-wide 2D headrest offers neck support, with two-dimensional adjustment indicated by its product description.
Desk clearance
The armrests flip up and tuck under a desk, which helps when the chair needs to move close to a compact workstation.
Included relaxation features
The recline supports breaks, but this model is sold without a footrest, limiting its appeal for buyers who want to stretch out in the chair.

Pros

- Multiple recline angles accommodate shifts between focused work and breaks.
- Flip-up armrests can tuck beneath the desk.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 for daily desk work if you want adaptive lumbar support, a full-mesh design, and recline positions for shifting between focused tasks and breaks.
Its widened cushion and extra-wide headrest add support features to assess against your own fit preferences.
It is also worth considering for compact workstations: the armrests flip up and tuck under a desk, and the chair supports up to 300 lbs.
The 3-year warranty and 30-day return period provide defined after-sale terms to factor into a purchase.
Who should skip it
Skip it if an integrated footrest is central to how you relax at your desk; this chair is explicitly a without-footrest model. The recline angles support breaks, but the chair does not provide that leg-stretching feature.
SIHOO B100 Review Analysis
Lumbar movement and recline
The B100's dual-back arrangement and elastic lumbar support are intended to follow movement rather than hold the back in one position.
Three recline angles give the chair defined options for upright work and more relaxed breaks, although preference for a particular recline setting is personal.
Airflow and seating fit
The full-mesh construction is aimed at airflow during long desk sessions, while the widened cushion is designed to spread weight more evenly.
Those features are useful considerations for warm rooms or buyers seeking a broader seat, but the actual fit still depends on body shape and desk setup.
Armrests and workspace
Armrests that flip up and tuck under the desk can help the chair sit closer to a compact workstation when the arms are in the way.
Their movement with the recline adds flexibility, though buyers should check that their desk height and preferred arm position work with this style.
What the design leaves out
This is a task-oriented chair with recline for breaks, but its title makes clear that a footrest is not part of the setup.
Buyers who want a chair that supports their legs while reclining should treat that as a meaningful design limitation.

Prefer the B100 Pro if a retractable footrest and 4D armrests are important for stretching out or adjusting arm position.
Choose the B100 if you do not need the footrest and its flip-up armrests meet your desk setup needs.

Is SIHOO B100 Worth It?
The SIHOO B100 is worth considering for desk workers who want adaptive lumbar support, mesh construction, several recline positions, and armrests that can tuck under a desk.
Its widened cushion and up-to-300-lb capacity add practical fit points, while the 3-year warranty gives a defined coverage period.
It is a weaker fit if a footrest is essential or if you need to confirm the seat and headrest suit your body before committing.
For a straightforward everyday desk chair with airflow, adjustable recline, and stowable armrests, the B100 has a coherent feature set; weigh those benefits against the no-footrest design and your own fit preferences.
