Cortex

3D knitted innovation, ergonomic breathability

Effortless Ergonomics

Set by no one. Right for everyone.

Automatic tension

The recline matches itself to your body weight. No wheel to hunt for, no guesswork.

Lumbar, dialled in

Height-adjustable lumbar support puts firmness exactly where your lower back asks for it.

The finishing touches

Height-adjustable arms and a seat slider complete the personal fit.

Four Colours, One Chair

A task chair you would choose for how it looks.

Black, grey, mint and brick red, with details to match. Cortex is designed to be seen, not hidden under a desk.

The design-led studio

A chair that holds its own in a space where every object was chosen on purpose.

Brick red Cortex against a matching tonal interior palette, colour-blocked composition

The brand-matched fitout

Carry an interior palette through to the seating, instead of stopping at the walls.

Black Cortex in classic open plan, monochrome grade, quiet and premium

The classic floor

In black or grey, Cortex does understated as well as it does colour.

The Cortex Back

Knitted, not upholstered.

One engineered surface

Cortex’s back is a single 3D-knitted panel. Structure and comfort in the same layer, with a stitching pattern you will not find on another chair.

Breathes by construction

Knit is porous by nature. Air moves through the back itself, not through perforations in padding.

Flexes where you do

The elastic knit distributes weight evenly and keeps supporting you as you shift.
