Product Overview

Modern and beautifully crafted, the D40 DRAGONFLY-S Ergonomic Dual-Back Office Chair features innovative elements that provide enhanced lateral support. Engineered with core ergonomic principles, every sit feels like a breakthrough in comfort and support.

Who is the D40 DRAGONFLY-S Ergonomic Dual-Back Office Chair Best Suited For?

• Individuals with limited mobility due to back or hip pain and tightness
• Professionals seeking office chairs that offer balanced right and left lumbar support
• Anyone needing extra spinal and lumbar support along with premium, upgraded functionality

Dynamic Variable Lumbar (DVL) Support 

One of the D40 DRAGONFLY-S's most groundbreaking ergonomic innovations lies in its support system—automatically adjusting every time you sit down. It adapts to your body and flexes with each movement. The Dynamic Variable Lumbar (DVL) system adjusts according to your weight, height, posture, and the pressure applied, rotating with you to ensure comfort and support as you shift positions. This lets you focus on your work—not your back.

Korean WINTEX Elastic Mesh Fabric

Soft, adaptive, and anything but ordinary. Our core elastic mesh fabric delivers breathable, ventilated comfort while providing all the support you need for lasting ease. Having passed over 100,000 durability abrasion cycles, WINTEX became one of the renowned mesh suppliers for the famous brand Herman Miller in 2017.

Waterfall-Edge Seat — Gentle on Your Knees, Ergonomic by Design

Crafted with long hours in mind, the D40 DRAGONFLY-S features a waterfall-edge seat that enhances comfort behind the knees. Its softly contoured front edge promotes better circulation and reduces pressure, while the built-in foam padding delivers lasting support. Designed to blend form and function, this thoughtful detail keeps you comfortable and well-aligned throughout the day.

Ratchet-Style Backrest Design

The ratchet-style backrest enhances dynamic, adaptive lumbar support that conforms to the natural curve of your body. It offers four levels of height adjustment, allowing your spine to settle into the most relaxed and comfortable position.

Patented Aluminum Alloy Lever with Synchronized Tilt Mechanism

This independently developed innovative double-spring control system, patented in 2010, features a polished aluminum alloy frame. The surface of the alloy is wear-resistant and rust-proof, delivering a sense of high quality and strength.

Thanks to its refined engineering and structure:

• The backrest tilt offers four adjustable angles, with a maximum tilt of 130 degrees
• Users can enjoy a relaxing posture while the seat cushion remains relatively stable

Pressure-Relieving Seat Cushion Design

The seat cushion incorporates a specially contoured ergonomic shape that helps reduce pressure on the user. Its thoughtful design prioritizes comfort and care, making long hours of sitting more pleasant and supportive.
