Read Amazon ReviewsSIHOO B100 Pro
A mesh office chair for desk workers who want adjustable lumbar support, a retractable footrest, and several ways to recline and position their arms.
- Adaptive lumbar support uses a dual-back design that moves with the spine.
- A retractable footrest supports stretching out during a break.
- Four-dimensional armrests can be adjusted, rotated, or flipped.
- The recline locks at three angles: 110°, 125°, and 135°.
Pros
- Adaptive lumbar support follows changes in sitting position.
- A retractable footrest makes it easier to stretch out during breaks.
Consider before buying
- The broad feature set is most useful if you will use both the recline and footrest; buyers seeking only a basic upright desk chair may not need those extras.
- Check the chair's fit at your desk before buying, especially if you plan to use the footrest or recline in a compact room.
Read the full review summary
The B100 Pro combines a full-mesh seat and back with adaptive lumbar support, a retractable footrest, and a wide 3D headrest.
That mix gives it appeal for people who spend much of the day at a desk but also want a chair that can recline for a reading or gaming break.
Its flexibility is the main reason to consider it: the armrests rotate or flip, and the recline has three angles for shifting between an upright posture and a more relaxed position.
It makes the most sense for a home office where the chair can serve both work and downtime, rather than a setup that needs a simple task chair alone.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if your home-office chair needs to cover focused desk time as well as relaxed breaks. The moving lumbar design, adjustable armrests, and lockable recline give you multiple ways to change posture through the day.
It is also worth considering if you prefer a mesh seat and back and want a headrest and footrest included in the chair's design.
The 300 lb capacity provides a specific limit to compare with your needs before ordering.
Who should skip it
Skip it if you need a chair specifically for swimming-pool areas or expect an open, armless design; its reclining footrest and adjustable armrests are central parts of the setup.
If your priority is only an upright chair for desk tasks, consider whether the footrest and multiple recline positions will earn their space in your room.
SIHOO B100 Pro: Workday Flexibility and Break-Time Design
Lumbar support for changing posture
The adaptive lumbar system is intended to move with the spine as the sitter leans forward, sits upright, or shifts position.
That makes it a relevant feature for people who alternate between concentrated work and meetings, though the right fit still depends on individual posture and desk setup.
A chair that can recline for breaks
The footrest and lockable recline are the features that broaden this chair beyond a standard work posture.
The three stated angles support different degrees of leaning back, while the pull-out footrest gives the legs a place to extend; buyers should check that the reclined position suits their room layout.
Mesh and headrest for long desk sessions
A mesh surface across the back and seat may appeal to buyers who prefer airflow-oriented materials.
The wide 3D headrest is designed for neck support during typing, calls, or video conferences, so those who rely on head support should check how its adjustment range fits their body and screen height.
Capacity and room planning
The chair has a 300 lb capacity, with a reinforced metal base and a Class 4 SGS-certified gas lift.
Its reclining positions and extending footrest make floor space worth checking in advance, particularly when the chair will sit near a wall or other furniture.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want one mesh chair for work, study, and off-duty breaks.
Adaptive lumbar support, a retractable footrest, adjustable armrests, and three lockable recline angles give it a flexible role in a home office.
Check the 300 lb capacity against your requirements and make sure you have space for the footrest and recline.
If your chair will serve only as a simple upright workstation seat, this design's relaxation features may be more than you need.
