Read the full review summary

Who Should Buy B100 SE Chair?
Good fit
Buy the B100 SE if you want a cushioned desk chair with lumbar support designed to follow changes in posture. The adjustable headrest and seat-height range are useful fitting controls for a home office or study setup.
It also makes sense for someone who wants to sit more upright during focused work and recline during a break. The three lockable positions provide that choice without relying on a single fixed seating angle.
Who should skip it
Skip it if a soft cushioned seat is a poor match for your preference and you specifically want the feel of a traditional mesh seat.
Consider another style if you need a chair whose fit is confirmed for a particular body size; compare the stated seat-height range and try to assess headrest positioning before committing.
B100 SE Chair: Comfort, Support and Fit
Cushioning versus mesh feel
The seat is a central part of this chair’s appeal: plush padding creates a softer sitting experience than traditional mesh.
That points toward buyers who like a cushioned surface, while someone who prefers mesh under them should pay close attention to that design choice.
Lumbar support through posture changes
The lumbar support is designed to follow the spine when you lean forward, sit upright or shift position.
That moving-support concept fits a desk routine with varied postures, although the listing provides no basis to promise a particular comfort outcome for every body.
Recline for work and breaks
Three lockable recline angles let you choose between work mode and a more relaxed position.
This is useful if you prefer a chair that can stay upright for desk tasks and recline for short breaks, but it is not presented as a flat sleeping surface.
Sizing the chair to a desk
The seat adjusts from 18.3 inches to 21.9 inches, and the headrest is adjustable. Check those points against your desk height and preferred neck support position, especially if a precise fit matters to your setup.
