A mesh desk chair with adaptive lumbar support, adjustable armrests and a retractable footrest for people who want work and relaxation features in one seat.
- Dual-back adaptive lumbar support is designed to move with the spine as posture changes.
- The footrest retracts when it is not needed and pulls out for stretching or reclined breaks.
- Four-dimensional armrests can adjust, rotate or flip; recline locks at three listed angles: 110°, 125° and 135°.
- A widened cushion and 3D ultra-wide headrest provide the chair’s seat and neck-support features.
Pros
- Footrest adds a stretching and lounging option to a desk chair.
- Armrests can be adjusted, rotated or flipped to suit different desk postures.
Consider before buying
- The footrest and reclining features are most useful if you plan to take seated breaks; buyers wanting only a basic work seat may not benefit from that extra setup.
- The recline is described through three fixed angles, so consider whether those positions match the way you prefer to lean back.
Read the full review summary
The B100 Pro combines a dual-back design that moves with the spine, a full-mesh seat and back, and a footrest that pulls out for stretching.
Those features make it a compelling fit for a home office that also serves for gaming or casual breaks, particularly if adjustable arm positioning matters at your desk.
Its strongest appeal is range of adjustment: the armrests can rotate or flip, the headrest is described as 3D and ultra-wide, and recline locks at three angles.
Consider the tradeoff between this relaxation-oriented setup and a simpler office chair if your priority is straightforward desk use and you do not expect to use the footrest or reclining positions.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if your home office doubles as a place to game or relax and you want a pull-out footrest alongside a reclining chair. The added break-time setup is a key reason to consider this model.
It also suits desk users who value adjustable arm placement, a wide headrest and mesh across both the seat and back.
Check the 300 lbs capacity against the intended user and confirm that the chair’s dimensions fit your workspace.
Who should skip it
Skip it if your needs are limited to a straightforward desk chair and you are unlikely to use a retractable footrest or recline. Much of this chair’s appeal centers on those break-time features.
Look elsewhere if the stated capacity does not suit the intended user, or if you need dimensions confirmed before deciding on fit.
SIHOO B100 Pro Review Analysis
Lumbar support and adjustment
The dual-back design is intended to move with the spine during forward, upright and shifting postures.
Along with armrests that rotate or flip and a 3D headrest, it offers several adjustment points; buyers who want a highly fixed, simple seat may not use all of them.
A chair for work and pauses
The pull-out footrest and lockable recline make breaks part of the chair’s intended use.
This makes sense for a room where one chair serves for work and casual gaming or media, but the benefit depends on whether you prefer to recline at your desk.
Mesh and seat feel
A full-mesh seat and back make airflow a central design choice, while the widened cushion spreads weight across a broader sitting area.
Buyers who prefer a padded upholstered seat may favor another chair style; the mesh design alone cannot establish personal comfort.
Capacity and support terms
The reinforced metal base, Class 4 gas lift and stated 300 lbs limit give buyers concrete points to check against their requirements.
The provided coverage is 36 months, and returns are offered within 30 days, which may help when weighing purchase support.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want a mesh desk chair with adaptive lumbar support and expect to use its footrest, adjustable armrests and reclining positions.
Its work-to-break flexibility is the clearest reason to choose it.
Before buying, check that the 300 lbs capacity fits the intended user and that the dimensions work in your office.
If those points fit and you value a chair that can serve for work and reclining breaks, the B100 Pro has a coherent feature set; if you want only a basic work seat, its relaxation features may go unused.
