RIM FLEXi Ergonomic Mesh Back Office Chair - ST1 Synchro Mechanism

The RIM FLEXi ergonomic office chair is designed to deliver comfort, adjustability, and long-term support for both professional and home office environments. Combining refined European design with considered ergonomics, the FLEXi adapts easily to different users and working styles.

A breathable mesh backrest with height adjustment supports airflow and posture, while the high-quality synchro mechanism allows the seat and backrest to move together naturally as you recline. This encourages dynamic sitting and helps reduce fatigue during long periods of desk work.

Finished in black, the FLEXi has a clean, professional appearance suited to a wide range of modern office interiors.
