Read the full review summary
The B100 Pro combines a dual-back lumbar design with a full-mesh back and seat, four-dimensional armrests and a three-position lockable recline.
Its retractable footrest adds a way to stretch out during a break without leaving the chair, so the feature set suits a home office that also serves for gaming or unwinding.

Consider the dimensions and adjustment range against your desk and body before buying, especially if you rely on precise seat-fit settings for long sessions.

Who Should Buy B100 Pro Chair?
Good fit
Choose the B100 Pro if you want an office chair that can shift between upright desk work and reclining breaks.
Its three lockable recline positions pair with a retractable footrest, giving the chair a clear role beyond sitting upright at a workstation.
It also fits buyers who want multiple armrest adjustments and a mesh back and seat.
The dual-back lumbar design is intended to follow position changes, while the wide headrest and widened cushion add further contact points for desk sessions.
Who should skip it
Skip it if your required weight capacity exceeds 300 lbs; this chair’s stated support limit is up to 300 lbs.
If you need a recline angle outside 110°, 125° or 135°, look for a chair with positions that match your preferred range.
B100 Pro Chair: Comfort and Adjustability in Daily Use
Lumbar support for changing positions
The adaptive lumbar setup is paired with a dual-back structure designed to move with the spine as the sitter leans forward or returns upright.
That makes posture changes central to the chair’s appeal, though the design alone cannot guarantee a comfortable fit for every body.
Recline and the footrest
The chair has three lockable recline angles and a retractable footrest, so it can accommodate a transition from desk work to a more stretched-out break.
Buyers should make sure those fixed positions suit how they prefer to sit and rest.
Armrests and desk clearance
The 4D armrests rotate and flip, with the option to slide them under a desk. That flexibility may help with workstation positioning, but desk clearance still depends on the relationship between the chair and the desk.
Materials, support limit and ownership
A full-mesh back and seat promote airflow, while the chair uses a reinforced metal base and a Class 4 SGS-certified gas lift.
Its capacity is up to 300 lbs, and coverage is 36 months, details buyers can weigh alongside fit and adjustment needs.
