A mesh office chair for buyers who want adaptive lumbar support, a footrest and several recline and armrest adjustments for work and breaks.
- Elastic lumbar support uses a dual-back design intended to move with posture changes.
- Retractable footrest for stretching out during reclined breaks.

- Wide seat cushion and 3D ultra-wide headrest.
Pros
- Dual-back lumbar design is intended to adapt across different sitting positions.

Consider before buying
- If you prefer a fixed-feeling chair, the combination of moving lumbar support, adjustable armrests and multiple recline positions may require more setup to settle on a preferred posture.
- The footrest is geared toward reclining breaks; buyers who only need a straightforward work chair may not use that feature enough to justify the added mechanism.
Read the full review summary
The B100 Pro combines a dual-back design with elastic lumbar support intended to move with the sitter through forward leaning, upright sitting and position changes.
A retractable footrest and three recline angles add a relaxation option for breaks, gaming or study sessions.
Its full-mesh seat and back, wide cushion and 3D headrest are aimed at longer desk sessions, while flip-up, rotating armrests offer positioning flexibility.
Consider it if those adjustments and a built-in footrest matter more than keeping the chair simple; its range of moving parts makes careful setup and fit checks worthwhile.

Who Should Buy SIHOO B100 Pro?
Good fit
Choose the B100 Pro if you want a single chair for desk work and reclined breaks. Its retractable footrest, three recline angles and adjustable armrests give it a broad posture range for home office, gaming or study use.
It is also a reasonable fit for buyers who prefer mesh over a padded back and want a wide headrest and cushion in the same chair.
Check that the up-to-300-lb capacity and the chair’s adjustment range fit your body and desk setup.
Who should skip it
Skip it if you need a chair for swimming or other wet use; this chair is designed for desk work, gaming and study sessions.
It may also be a poor fit if you want a basic work chair and have no interest in a footrest or reclined breaks; much of its design emphasis is on posture changes and relaxation.
SIHOO B100 Pro Review: Work Posture and Breaks
A lumbar design for changing positions
The dual-back support is meant to move with the sitter rather than hold one rigid position.
That approach may appeal to people who alternate between leaning forward and sitting upright, though a feature description cannot guarantee a comfortable fit for every body.
Recline and armrest adjustments
The chair offers three recline angles, plus armrests that adjust, rotate and flip. This range may help with different desk arrangements and break positions, though buyers should choose settings that suit their posture and workspace.
Mesh, cushion and headrest
Mesh spans the seat and back, while the cushion is widened and the headrest is 3D and ultra-wide.
These features point to an airflow-focused design with support surfaces intended for longer sessions; comfort still depends on personal fit and preference.
Capacity and construction
A reinforced metal base and Class 4 SGS-certified gas lift are paired with an up-to-300-lb capacity. Buyers should compare that limit with their needs and ensure the chair’s footprint and adjustment layout work with the intended desk area.

Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro Office Chair is worth considering if you want a mesh desk chair that can switch between work positions and reclined breaks. Its clearest differentiators are the retractable footrest, dual-back lumbar concept and flexible armrests.
Before buying, confirm that its up-to-300-lb capacity and adjustment-heavy design fit your requirements.
If those tradeoffs align with your workspace and routine, the B100 Pro makes the most sense for someone who will use both its desk-chair support features and its footrest for breaks.
