Read the full review summary
The B100 brings together adaptive lumbar support, an extra-wide headrest, three recline angles and a widened cushion.
Its full-mesh design and flip-up armrests add practical flexibility for everyday desk work, including setups where the chair needs to tuck under the desk.
Consider it if you want a chair with several ways to adjust posture and a stated weight capacity of up to 300 lbs.
The tradeoff is clear: there is no footrest, so buyers who want to stretch out with leg support should look at a different design.

Who Should Buy SIHOO B100?
Good fit
Choose the B100 if you want lumbar support designed to move with you and three recline choices for shifting between focused tasks and short breaks.
It also fits buyers who need armrests that can lift out of the way: they adjust with recline and tuck under the desk. The mesh construction and widened cushion round out the everyday desk-work setup.
Who should skip it
Skip it if a footrest is central to how you plan to use a recliner-style office chair; the B100 is explicitly a chair without one.
Pass if the up-to-300-lb capacity does not meet your requirements, since that is the stated limit for this chair.
SIHOO B100: What Its Adjustments Mean for Desk Work
Support that moves with posture
The B100 pairs a dual-back lumbar structure with three recline angles.
That combination gives you ways to change position during the day while keeping lumbar support central to the design; it does not guarantee that the fit will suit every body, so consider your own preferred posture and chair dimensions before choosing.
Making room under the desk
The armrests flip up, adjust with recline and tuck under a desk. That is a useful arrangement for compact workspaces or for sliding the chair closer to a desk when the arms are in the way.
Mesh and cushion choices
Full-mesh construction is intended to keep air moving, while the widened cushion is designed to distribute weight more evenly. These are sensible priorities for long desk sessions, though actual comfort depends on individual fit and preference.
Capacity and downtime
The reinforced frame and heavy-duty base support up to 300 lbs, while the recline settings let you shift back for a break.
Since this model has no footrest, it does not offer the extended-leg lounging setup some buyers want.

Is SIHOO B100 Worth It?

Its mesh construction and widened cushion add practical design choices for extended desk sessions.
Pass if you need integrated leg support for lounging, since the B100 has no footrest, and make sure its up-to-300-lb capacity suits you.
For a desk-focused chair that emphasizes adjustable support and space-conscious armrests, it is a reasonable fit on paper.
