## Before you buy

- Listing details are contradictory or inconsistent: the model is named B100-M102 but another field gives model number B300-XX-JP, and its dimensions are listed both as 27.56 x 28.35 x 44.09 inches and 28.3"D x 27.6"W x 51.6"H. Recline angles, adjustable seat-height range and a 300-pound limit appear in feature text rather than the compact details, so confirm these specifications and the selected configuration before ordering. The item highlight says without footrest, while the contents list includes an LED light, so confirm the package contents as well.

## In the box

- Arm pad (Included)
- Caster (Included)
- Cushion (Included)
- LED light (Check selected pack): The contents list names an LED light, but the listing highlight describes a chair without a footrest. Confirm the selected package contents.

## A good fit for

- Desk and home-office users wanting adjustable lumbar support, headrest and seat height.
- People who prefer a mesh-backed chair and want multiple lockable recline positions.
- Buyers whose desk setup works with the listed 18.3-to-21.9-inch seat-height range.

## Less suited to

- People needing a chair with a footrest, which the listing highlight says is not included.
- Buyers whose required capacity exceeds the listed 300-pound recommendation.
- Anyone who needs confirmed model or dimensions before purchase without first clarifying the listing inconsistencies.

## Customer feedback

Customer feedback highlights perceived strengths in quality, lower-back support, ergonomics, sturdiness and appearance, with some customers describing the chair as suitable for long work hours. That aligns with the listing’s mesh construction and adjustable lumbar and headrest features, though those product claims do not guarantee an individual fit. Assembly and adjustability experiences are mixed, including reports of confusing instructions and armrests that flex too much. These concerns matter if straightforward setup or firm arm support is a priority.
- Positive themes: Customers describe the chair as well made and supportive for the lower back.
- Positive themes: Some feedback praises its ergonomics, sturdy feel and appearance.
- Mixed feedback: Assembly experiences vary, with some finding it easy and others describing confusing instructions.
- Mixed feedback: Feedback on adjustability varies, and some customers report excessive armrest flex.
