Read the full review summary
The B100 Pro combines a dual-back design intended to move with the spine, a retractable footrest, four-dimensional armrests, and three recline angles.
That mix suits a home office where the chair needs to serve for work as well as occasional lounging or gaming breaks.
Its full-mesh seat and back are intended to promote airflow, while the wide headrest and cushion add support surfaces for longer desk sessions.
The chair is a stronger fit for buyers who value adjustability and a footrest than for anyone seeking a simple, work-only seat.
The buying factors
SIHOO B100 Pro Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Lumbar support design
The dual-back construction is intended to move with the spine through forward-leaning, upright, and shifting postures, making it a central feature for desk use.
Recline and break options
Three lockable recline positions and a retractable footrest support a clear transition from work posture to stretching or reclining breaks.
Armrest flexibility
The 4D armrests can be adjusted, rotated, or flipped, giving buyers several ways to tune desk clearance and posture.
Breathable construction
Mesh across both the seat and back is intended to encourage airflow, a useful construction choice for extended sessions.
Headrest and seat support
A widened cushion and ultra-wide headrest provide broad contact areas, although their fit will depend on individual proportions and preferences.
Capacity and chair base
A reinforced metal base and Class 4 gas lift are paired with a stated capacity of 300 lbs, offering a useful published limit for shoppers to check against their needs.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a desk chair that can also support reclining breaks. The retractable footrest, three recline angles, and lockable recline make those features part of its core fit.
It is also worth considering if adjustable arm positioning matters in your workspace. The armrests adjust, rotate, or flip up, while the dual-back lumbar design is intended to move with posture changes.
Check the stated weight limit against your needs, and make sure a wide headrest and cushion feel appropriate for your build and desk arrangement.
Who should skip it
Skip it if you want a minimal work chair and have no use for reclining breaks or a footrest; those functions are prominent parts of this design.
It is also a poor fit if your required supported load exceeds 300 lbs, since the published capacity is up to that limit.
SIHOO B100 Pro Review Analysis
Lumbar movement for changing postures
The dual-back support is designed to move with the spine as you lean forward, sit upright, or shift.
That makes the chair relevant to people who change position through a workday, though the design description alone cannot determine whether its support shape will suit a particular back.
A work chair with a dedicated break mode
The footrest and three recline positions make relaxation a central use case alongside desk work.
Buyers should consider whether that flexibility is useful in their room and routine, since reclining a chair also needs clear space behind and in front.
Mesh, headrest, and workspace fit
The full-mesh seat and back are intended to promote airflow, and the wide headrest adds another support point. Check desk clearance and fit in your setup, especially if you expect to use the flip-up armrests or recline regularly.
Capacity and ownership considerations
The chair combines a reinforced metal base with a Class 4 gas lift and a stated capacity up to 300 lbs.
Its stated 36-month coverage and 30-day returns may be useful terms to review before purchase, particularly if you expect daily use.

Consider the M57 if height-and-depth lumbar adjustment and its recline range are priorities; the B100 Pro suits buyers who specifically want a retractable footrest with its three-position recline.
- The M57 has lumbar support adjustable in height and depth, recline from 90° to 126°, and a waterfall-edge seat.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want adaptive lumbar support, flexible armrests, and a chair that can recline with a footrest for breaks.
Its mesh construction and broad headrest round out a feature set aimed at extended desk use.
It is a less compelling fit if you will not use the reclining and footrest features, or if the 300 lb stated limit does not meet your needs.
Check how its wide seat, headrest, and armrest setup fit your body and workspace before choosing it for daily sitting.
