A mesh office chair for desk users who want adjustable lumbar support, reclining positions and a pull-out footrest for breaks.
- Dual-back design with elastic adaptive lumbar support.
- Retractable footrest for stretching out during breaks.

- The footrest adds a way to stretch out during desk breaks.
Consider before buying
- The footrest and recline features take up consideration in a workspace where the chair needs to tuck away neatly; check your desk clearance and available floor space.

Read the full review summary
The B100 Pro combines a full-mesh back and seat with a dual-back design and elastic lumbar support intended to move with the spine.
Its adjustable recline and armrests give desk users several ways to change posture during work or a break.
It is especially relevant if you value a pull-out footrest and a wide headrest for relaxing, gaming or watching a movie at your desk.
The tradeoff is a more lounge-oriented feature set; buyers focused on straightforward sitting should decide whether those extras fit their workspace and routine.

Lumbar adjustability

A retractable footrest and wide headrest make the chair more oriented toward stretching out during breaks as well as desk work.

Mesh covers both the back and seat, a design intended to encourage airflow through long workdays.

Who Should Buy SIHOO B100 Pro?
Good fit
Consider the B100 Pro if you spend long periods at a desk and want adjustable lumbar support, armrests and recline positions to help vary your posture.
The mesh seat and back are also intended to promote airflow during extended use.
It is a stronger fit for people who expect to use a chair for short relaxation breaks as well as work: the footrest pulls out, and the wide headrest supports the neck during typing, calls or video conferences.
Who should skip it
Skip it if you do not want a reclining chair with a pull-out footrest or do not have room to extend one during breaks. Those features are central to its work-and-relaxation setup.
Look elsewhere if the 300 lbs support limit does not suit the intended user, or if none of the three stated recline positions matches the posture you want.
SIHOO B100 Pro Review Analysis
Support that moves with you
The dual-back layout and elastic lumbar support target users who change position through the day.
That design may appeal to people who alternate between leaning forward and sitting upright, though the listing's comfort language is not a substitute for checking whether the chair's support shape suits your body.
A chair with a break mode
The footrest, recline and wide headrest give the chair a clear relaxation role alongside desk work. This can be useful for gaming or short movie breaks, but it also makes room and desk clearance worth checking before purchase.
Materials and fit checks
The full-mesh seat and back are designed to encourage airflow, while the widened cushion and headrest add contact areas to consider when assessing fit. Confirm the 300 lbs support limit and available floor space against your intended use.
Coverage and ownership
The product includes 36-month coverage and a 30-day easy-return period, giving buyers a stated window for resolving fit or product concerns. Review the return and coverage terms at purchase so the conditions are clear.
