Read the full review summary
The B100 combines a dual-back design with elastic dynamic lumbar support intended to follow the spine’s natural curve.
Its recline options and flip-up arms add useful flexibility for alternating between focused work, relaxed breaks, and tucking the chair under a desk.
Its full-mesh construction, widened cushion, and extra-wide 2D headrest make it a practical fit for everyday desk use, especially if airflow and neck support matter to your setup.
The tradeoff is a straightforward chair without a footrest, so buyers wanting a place to stretch their legs during breaks 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 design
Elastic dynamic lumbar support and a dual-back design are intended to follow the natural curve of your back, a useful foundation for buyers prioritizing adjustable-feeling support while working.
Recline flexibility
Three recline angles provide distinct positions for focused work and relaxed breaks, giving the chair useful flexibility without relying on a footrest.
Desk-clearance features
Flip-up armrests that tuck under a desk make the B100 easier to fit into a compact workstation when the chair is not in use.
Breathable construction
Full mesh across the chair is designed to promote airflow, a sensible feature for people who prefer a less enclosed seat during long desk sessions.
Head and seat support
An extra-wide 2D headrest and widened cushion cover two useful contact points, though the fit will depend on whether their shape and adjustment suit your body and desk posture.
Weight capacity
The chair supports up to 300 lbs, a concrete fit consideration for buyers checking capacity before purchase.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want lumbar support designed to move with you and the option to change posture across three recline angles.
The flip-up armrests are particularly useful when desk clearance matters or you want to slide the chair closer to your workstation.
It also suits buyers who prefer full mesh and want an extra-wide headrest and widened cushion for regular desk work.
Check the stated capacity against your needs, and consider whether a 2D headrest provides the adjustment you prefer before choosing.
Who should skip it
Skip this configuration if a built-in footrest is essential for stretching out during reclined breaks. The B100 is a desk-focused chair with recline positions, but its product name identifies it as a model without a footrest.
SIHOO B100 Review: How Its Support Fits Desk Work
Adaptive lumbar design
The B100’s central ergonomic feature is elastic dynamic lumbar support paired with a dual-back structure.
That design is intended to follow the back’s natural curve as you move, making it relevant for buyers who shift posture rather than remain fixed in one position.
Treat that as a design rationale, not a guarantee that the chair will fit every body; adjustability and personal fit remain important.
Recline and workstation flexibility
The three recline angles create a defined choice between upright work and more relaxed positions.
The flip-up arms complement that setup by tucking under the desk, so the B100 makes practical sense in a compact workspace where chair storage and desk approach matter as much as leaning back.
Mesh, cushion, and headrest
The all-mesh approach prioritizes airflow, while the widened cushion is intended to spread weight more evenly.
An extra-wide 2D headrest adds neck support, but its stated adjustment type makes fit worth checking if you rely on precise headrest positioning.
For long sessions, comfort will depend on how these shapes and support points suit your build and posture.
Capacity and ownership support
The B100 supports up to 300 lbs and includes a 3-year warranty with 30-day easy returns.
Those terms help define the purchase’s capacity and initial support window; check that the capacity fits your needs and review the applicable return and warranty conditions before ordering.

Read Amazon ReviewsSIHOO B100 Pro Ergonomic Office Chair
Prefer the B100 Pro if you want a retractable footrest for stretching out or the added positioning options of 4D armrests and a 3D headrest.
The B100 remains the simpler fit if a footrest is unnecessary and flip-up arms with adaptive support meet your needs.
- The B100 Pro adds a retractable footrest, three recline angles, and 4D armrests that adjust, rotate, or flip. Its headrest is 3D and ultra-wide.

Is SIHOO B100 Worth It?
The SIHOO B100 is worth considering if you want adaptive lumbar support, breathable full mesh, three recline positions, and armrests that can tuck away at a desk.
Its widened cushion, extra-wide headrest, and up-to-300-lb capacity round out a practical office-chair feature set.
It is a less suitable choice if a footrest is central to your breaks or if you need more headrest positioning than a 2D design offers.
If those tradeoffs fit your setup, the B100 makes the most sense as a flexible desk chair rather than a lounge-style reclining seat.
