## Before you buy

- The listing gives a separate overall size of 43D x 61W x 110H centimetres, a seat height of 21 Inches and a back interior height of 123 Centimeters alongside other dimension claims. These measurements are inconsistent or unclear, so confirm the relevant chair and seat dimensions before purchase. The listing also claims a 150 kg capacity in its title and feature text, while the separate maximum weight recommendation is 330 Pounds. Its model name is M57 but its model number is B100-LITE-JP-4. These discrepancies do not establish a product defect.

## In the box

- Cushion (Included)

## A good fit for

- Desk users seeking adjustable arm support, lumbar support and a headrest.
- Buyers who prefer a mesh back and seat and want a chair with tilt and height adjustment.

## Less suited to

- Buyers who need fully consistent published measurements or a clearly confirmed capacity stated in a single unit.
- Buyers prioritising assured long-term hydraulic reliability, given reports of mechanism problems in customer feedback.

## Customer feedback

Customer feedback reports positive experiences with quality, comfort, value, ease of assembly and adjustability. Lumbar support is appreciated, but ergonomic feedback is mixed, including a concern about uneven weight distribution. Some customers also report hydraulic mechanism failures after one year. These reports matter if the chair is intended for regular desk use, where sustained support and mechanism reliability are relevant. They describe customer experiences, not verified performance findings.

- Positive themes: Feedback describes the lumbar support and adjustability positively.
