Read the full review summary
The B100 Pro combines a dual-back design intended to move with the spine, a full-mesh seat and back, and a retractable footrest.
That mix makes it a practical candidate for a home office where the chair needs to handle work sessions as well as reclined breaks.
Its adjustable armrests, three recline angles and wide headrest offer several ways to change posture during the day.
Consider it if those adjustments and a footrest matter more to you than keeping the chair simple; the stated weight capacity is 300 lbs.
The buying factors
SIHOO B100 Pro Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar adjustment
The dual-back lumbar support is designed to move with the spine as sitting posture changes, which is useful for workers who shift between leaning forward and sitting upright.
Recline options
Three recline angles create options for upright work and more relaxed breaks, with a lockable recline for setting a preferred position.
Armrest positioning
The 4D armrests can be adjusted, rotated or flipped, giving buyers more positioning choices and a way to move them out of the way under a desk.
Breathable construction
Mesh covers both the back and seat, a construction choice aimed at promoting airflow during longer desk sessions.
Break-time flexibility
A retractable footrest gives the chair a more relaxed setup for stretching out during a break, gaming or a movie session.
Capacity and base
The reinforced metal base and Class 4 SGS-certified gas lift are paired with a stated capacity of up to 300 lbs, a useful fit check before purchase.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if your desk routine includes posture changes and you want lumbar support designed to move with you. Its dual-back approach is intended to accommodate leaning forward and sitting upright during the day.
It also fits buyers who want a chair to cover short relaxation breaks as well as desk work.
The retractable footrest, lockable recline and flip-up armrests provide configuration options for shifting between tasks and taking space under a desk when needed.
Who should skip it
Skip it if a footrest and multiple recline settings would go unused; those adjustments are central to the chair’s break-time flexibility. Also confirm the capacity works for the intended user before buying.
SIHOO B100 Pro: How Its Adjustments Fit a Home Office
Support for shifting posture
The dual-back design is meant to follow the spine as the sitter leans forward or sits upright.
That makes the chair relevant to desk users who change positions through the day, while personal fit will still depend on the sitter and setup.
Recline and break use
Three recline angles give the chair a clear work-to-break range, and the retractable footrest is intended for stretching out. Buyers should consider whether they will use a reclining break setup often enough to value the added feature.
Mesh and desk fit
The mesh seat and back are designed to promote airflow, while the armrests can flip up to slide under a desk.
This pairing may suit a compact work area where airflow and the ability to move the armrests matter.
Capacity and expectations
The chair’s base and gas lift are paired with a stated capacity up to 300 lbs. Treat that as a practical compatibility check, and weigh the feature set against how simply you want your desk chair to function.
