Info Overview

About the Lux.

Adaptive. Engineered. Supportive.

The LUX Chair is a high-back ergonomic task chair built around a dual mesh backrest. Two mesh layers are separated by a central structural support, so the outer layer flexes with the user while the frame behind it holds the shape of the back. Seat and backrest are cushioned in high-resilience moulded foam produced through a water-foaming process, and the whole assembly is carried on a five-star base with castors.

Adjustment is where the chair earns its place. Lumbar support, seat height, seat depth and armrest position can all be set independently, so one chair specification can accommodate a wide range of body sizes rather than requiring variants across a floor. A balanced tilt mechanism lets the backrest follow the user into a recline and lock at a chosen angle, making the shift between focused work and a moment away from the screen a matter of fingertip pressure. That adaptability suits open-plan offices, executive settings, meeting rooms and home workspaces equally.

Combining considered ergonomics, tested materials and a restrained visual language, the LUX Chair delivers seating that adjusts to the person rather than asking the person to adjust to it.

What makes it special.

Dual mesh backrest support

Dual mesh backrest support

The back is built from a double layer of elastic fabric over a strong central frame. The frame carries the load while the outer layers move with the user, cushioning the back as they lean into it. A pattern of Y-shaped perforations runs through the frame, letting the back breathe and giving it a structure that supports without feeling hard. The result holds its shape across every sitting position rather than flexing away under pressure.

Adjustment across every contact point

Adjustment across every contact point

Lux is built around lumbar support any user can set without a manual. The pad slides up or down through 40mm across six positions to meet the curve of the lower back, balancing load across the lumbar spine and the muscles around it. Seat depth slides forward and back for thigh support at any height, and 3D armrests adjust up and down, forward and back, and side to side. A newly developed mechanism opens the chair to a 140° recline with four locking positions, moved by fingertip.

Tested materials for daily use

Tested materials for daily use

Seat and back are upholstered in a mixed-colour weave that sets a bold tone against a deeper one. The fabric is soft and full to the touch, bringing a warmer, less corporate character to a workspace, and the mixed weave disguises everyday wear so the chair looks newer for longer. Tested to 30,000 Martindale cycles with colour fastness grade 4 and above, over a one-piece moulded foam seat made by a water-blown process.

FAQ Lux

Questions about this chair.

All FAQs
How is the lumbar support adjusted?

The lumbar support moves through six positions across a 40mm stroke, set by a handle at the back of the chair. This allows the backrest curve to be matched to the user's spine without changing posture to do it.

What adjustments does the chair offer?

Seat height, seat depth, lumbar position, armrest position and backrest tilt are all independently adjustable. Armrests adjust in three directions: height, forward and backward, and left and right.

How far does the backrest recline?

The tilt mechanism allows a maximum recline of 140°, with four locking positions so the backrest can be fixed at a chosen angle or left free to follow the user's movement.

What is the seat height range?

The seat adjusts between 440mm and 510mm, suiting standard desk heights and a wide range of users.

How durable is the upholstery?

The upholstery is tested to 30,000 Martindale cycles with colour fastness grade 4 and above. The mixed-colour weave also disguises everyday wear, helping the chair hold its appearance in continuous commercial use.
