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.
Its four-dimensional armrests rotate or flip, while the recline locks at three angles, making it a flexible option for focused desk work and occasional relaxation.
Consider it if you value lumbar adjustability, neck support, and a place to stretch your legs during a break.
The chair’s stated support limit and included coverage provide concrete purchase considerations, but its broad feature set is most useful when you will actually use the footrest, reclining positions, and movable armrests.

Who Should Buy B100 Pro Chair?
Good fit
Choose the B100 Pro if you want a mesh chair with adaptive lumbar support and adjustability for both desk work and breaks.
The footrest, lockable recline, and rotating or flip-up armrests are its most useful features for buyers who expect to change positions throughout the day.
It is also worth considering if you prefer mesh across the seat and back and want a wide headrest. Check the 300 lb. support limit, seat fit, and 36-month coverage against your needs before ordering.
Who should skip it
Skip this chair if its 300 lb. support limit does not meet your requirements. A simpler desk chair may also be a better fit if you do not expect to use a footrest, reclining positions, or adjustable armrests.
B100 Pro Chair: Support, Recline, and Everyday Fit
Lumbar movement for changing postures
The dual-back layout is intended to move with the spine as you lean forward, sit upright, or shift position.
That makes lumbar adaptation a central reason to consider this chair, though individual fit still depends on how the chair aligns with your body.
A chair with a break mode
The footrest pulls out for stretching, while the back locks at three recline angles.
Buyers seeking a work chair that can also support a reclined pause may get more value from these features than someone who sits upright at a desk all day.
Airflow and upper-body support
Mesh on the seat and back is intended to promote airflow, and the wide headrest is designed to support the neck.
Those details address common priorities for extended desk sessions, but do not replace checking seat fit and headrest position for your own posture.
Capacity and ownership terms
The stated support limit is up to 300 lbs., and the chair includes 36-month coverage plus 30-day easy returns. Confirm the weight limit and review terms suit your circumstances before purchase.

Choose the M18 if seat-height and back-support adjustment plus its 150kg capacity best match your needs; choose the B100 Pro if its retractable footrest and rotating or flip-up armrests are more useful to you.
- The M18 offers adjustable seat height, headrest, lumbar support, and back support, with a support capacity up to 150kg.
- The B100 Pro is suited to buyers who want a retractable footrest and four-dimensional armrests that rotate or flip, alongside adaptive lumbar support.
Is B100 Pro Chair Worth It?
The SIHOO B100 Pro is worth considering if you want an ergonomic mesh chair that combines adaptive lumbar support with a footrest, lockable recline, and movable armrests.
Those features give it a clear work-and-break focus for buyers who plan to use more than a basic upright seating position.
Check the 300 lb. support limit, fit, and coverage terms before buying.
If the footrest and recline are unlikely to matter in your routine, the chair’s broad adjustment set may offer little practical benefit; if they are priorities, this is a feature-rich option to consider.
