Read the full review summary
The B100 combines a moving lumbar support design with three recline angles, an extra-wide headrest and flip-up armrests.
That mix gives desk workers options for changing posture and tucking the chair beneath a compact desk when the armrests are raised.
Its all-mesh construction, widened cushion and stated support capacity make it a candidate for routine home-office use.
The chair’s strongest fit is buyers who value ventilation and adaptable positioning; the chair is explicitly sold without a footrest, so it is less suited to anyone who expects one as part of the setup.
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
The elastic dual-back support is designed to follow the user's natural curve while allowing movement, a useful approach for buyers seeking back support during desk work.
Position adjustment
Three recline angles offer a clear choice between upright work and more relaxed breaks, while the armrests move with the recline.
Head and arm support
The extra-wide 2D headrest supports the neck, and flip-up armrests provide desk-clearance flexibility. Buyers looking for more specified adjustment details may want to check that the listed controls match their preferred fit.
Breathable construction
Full mesh is intended to promote airflow during long hours, which makes the material choice relevant for buyers who prefer a more ventilated chair design.
Desk-space flexibility
The armrests flip up and tuck beneath a desk, a practical feature for compact work areas or when the chair needs to be pushed in.
Build and support terms
The chair has a reinforced frame and heavy-duty base, with a stated 300 lb capacity, a three-year warranty and 30-day returns. These are useful purchase details, though they do not establish long-term durability in every setting.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want a mesh office chair with a lumbar support design intended to move with you and a choice of three recline angles.
These features make it relevant for alternating between focused desk work and more relaxed breaks.
It is also a sensible candidate for compact workspaces: the armrests flip up and tuck under a desk, while the full-mesh build is designed to keep air moving during long hours.
Consider it if those practical features matter more than having a footrest included.
Who should skip it
Skip the B100 if a footrest is essential to your chair setup; this model is sold without one. Buyers should also compare the 300 lb capacity with their own requirements before choosing a chair.
SIHOO B100: Support, Recline and Desk Fit
Adaptive lumbar support for desk work
The B100’s dual-back approach is intended to follow the natural curve while allowing movement.
That design may appeal to buyers who dislike a chair that feels restrictive, though the useful fit depends on whether the support meets their own posture needs.
Recline choices for changing posture
Three angles give the chair a defined range for upright work and reclined breaks. The armrests adjust with the recline, tying arm support to those positions rather than treating it as a separate feature.
Mesh and cushion for everyday use
The full-mesh design aims to keep air flowing, while the widened cushion is intended to spread weight more evenly.
Together, those choices make the B100 worth considering for daily desk use, subject to personal preferences for seat feel and fit.
Capacity, warranty and ownership
A reinforced frame and heavy-duty base accompany a stated capacity of up to 300 lbs. The three-year warranty and 30-day easy returns add useful purchase terms, though neither guarantees a particular comfort or durability outcome.

Is SIHOO B100 Worth It?
The SIHOO B100 is worth considering if adaptive lumbar support, three recline positions, full mesh and armrests that tuck under a desk align with your workspace and sitting habits.
Its features target flexible everyday desk use, with a stated capacity of up to 300 lbs and a three-year warranty.
The B100 has no footrest, so it is a poor match if one is a must-have. Its elastic dynamic lumbar support follows your natural curve, and it offers three recline angles for shifting between focused work and breaks.
