Read the full review summary
The B100 combines an elastic lumbar support system with a dual-back design intended to move with the user.
Its full-mesh build and widened cushion make it a practical option for everyday desk work, while the extra-wide 2D headrest adds neck support and the armrests can flip up to clear a desk edge.
It is a better fit for buyers who prioritize a flexible work chair over lounge features.
Three recline angles support changes between focused work and breaks, but there is no footrest, so buyers seeking a place to stretch their legs while reclining should consider that limitation before choosing it.

Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.

Breathable materials
A full-mesh design promotes airflow, which is a useful material choice for long desk sessions.
Head and seat support
The extra-wide 2D headrest and widened cushion cover two useful contact areas, although personal fit will depend on the user's proportions and preferences.
Build and ownership support
A reinforced frame, heavy-duty base, stated capacity, and three-year warranty add practical ownership points for everyday use.

Who Should Buy SIHOO B100?
Good fit
Consider the B100 if you want a mesh desk chair with adaptive lumbar support and a headrest for longer work sessions.
The dual-back design is intended to follow movement, while the widened cushion and full mesh address everyday seating and airflow needs.
Its recline positions and flip-up arms are useful if you alternate between upright work, short breaks, and pushing the chair under a desk.
The stated capacity and three-year warranty may also matter to buyers weighing everyday use and longer-term ownership.
Who should skip it
Skip it if a footrest is central to how you plan to use a reclining chair. The B100 is explicitly a chair without one, so it does not meet that particular use case.
It may also be a poor fit if you need a broader recline range than the three positions provided; review those angles against your preferred working and resting posture before buying.
SIHOO B100 Review: Support and Desk-Fit Analysis
Adaptive lumbar support for changing posture
The elastic lumbar support and dual-back layout are intended to move with the user rather than hold the back in one fixed position.
That makes the chair worth considering for desk work that includes shifting between tasks, though the right feel and support remain personal fit decisions.
Recline settings for work and breaks
The three angles—110°, 125°, and 135°—give the B100 defined positions for focused work and more relaxed breaks. Buyers who prefer a continuously adjustable recline or a dedicated leg-rest position may find this setup restrictive.
Mesh, cushion, and headrest considerations
Full mesh promotes airflow, while the widened cushion is intended to spread weight more evenly and the extra-wide 2D headrest supports the neck.
Those features address common desk-chair contact points, but individual comfort depends on proportions and preferred cushioning.
Compact desk setup and ownership
The armrests tuck under a desk, giving buyers a way to bring the seat closer to a work surface or reclaim floor space.
A reinforced frame, heavy-duty base, capacity up to 300 lbs., and three-year warranty add practical ownership details for a home office chair.

Its strongest fit is everyday desk work where airflow and compact clearance matter.
