A mesh office chair with adaptive lumbar support, adjustable armrests, reclining positions and a retractable footrest for workdays that include time to unwind.
- Adaptive lumbar support uses a dual-back design intended to move with the spine.
- Retractable footrest for stretching out during breaks.
- 4D armrests adjust, rotate and flip; three recline positions are 110°, 125° and 135°.
- Full-mesh seat and back are designed to promote airflow.
Pros
- Dual-back lumbar support is designed to adapt as posture changes.
- Retractable footrest supports stretching out during breaks.
Consider before buying
- The footrest and recline functions favor a chair that can serve as a lounge seat, so buyers wanting a simple upright work chair may not use much of its feature set.
- Check the chair’s dimensions and fit against your workspace before buying, particularly if you plan to use the recline and footrest in a compact room.
Read the full review summary
The B100 Pro’s dual-back design is intended to move with the spine, while its retractable footrest makes it possible to stretch out during a break.
Together with a recline that locks at three positions, those features give the chair a work-and-relaxation focus for a home office or study space.
The full-mesh seat and back are designed to promote airflow, and the 3D wide headrest and widened cushion add support-focused features.
This is a feature-rich option for buyers who value adjustability and a footrest; it is less compelling for someone seeking a straightforward desk chair without reclined lounging features.

Who Should Buy SIHOO B100 Pro?
Good fit
Consider the B100 Pro if you want a desk chair that can also support reclined breaks. The retractable footrest and three locking recline angles are directly suited to stretching out between work sessions, gaming or study.
It is also worth considering if adjustable arm positioning and a moving lumbar-support design matter to you.
The 4D armrests can be rotated or flipped, while the dual-back design is intended to move with the spine as posture changes.
Who should skip it
Skip it if you want a basic chair mainly for upright desk work and have little use for a retractable footrest or multiple recline positions. Those features are central to the chair’s work-and-break design.
SIHOO B100 Pro Review Analysis
Support that follows posture changes
The dual-back arrangement is meant to move with the spine during forward-leaning focus, upright meetings and position changes.
That makes the support concept relevant to people who vary their posture during the day, though a feature description alone cannot establish personal fit or comfort.
A chair with a break mode
The retractable footrest and lockable recline shape the B100 Pro around alternating desk work with resting or entertainment.
Buyers should make sure they have enough room to extend the footrest and recline, especially if the chair sits close to a desk or wall.
Mesh and contact points
The seat and back both use mesh, while the widened cushion and wide headrest add distinct contact points.
These are design choices for airflow and broader support, but shoppers should still consider whether the chair’s shape and dimensions suit their body and desk setup.
Capacity and construction
The chair combines a reinforced metal base with a Class 4 SGS-certified gas lift and a maximum capacity of 300 lbs.
Treat that capacity as a key fit check, and consider the certification and construction details alongside the chair’s adjustment features when deciding whether it matches your needs.

Choose the M18 if adjustable seat height and back support with a 150kg capacity fit your priorities; choose the B100 Pro if a retractable footrest, three recline positions and 4D armrests better match how you use a chair.
- The M18 has adjustable seat height, headrest, lumbar support and back support, plus a stated capacity up to 150kg.
- Its mesh back and headrest make it a support-adjustment-focused desk chair.
- The B100 Pro combines a retractable footrest with 4D armrests and a dual-back lumbar design, suiting buyers who want reclined breaks and several armrest positions.
Is SIHOO B100 Pro Worth It?
The SIHOO B100 Pro is worth considering if you want an adjustable mesh chair that can move from desk work to reclined breaks.
Its adaptive lumbar design, 4D armrests, multiple recline positions and retractable footrest give it a broad feature set for that use.
It is a less natural match for buyers who want a straightforward upright chair and will not use the lounge-oriented adjustments.
Check that its up-to-300-lb capacity and the space needed for the recline and footrest align with your setup before choosing it.
