Concept Onyx

Concept Onyx presents a deep charcoal-black ground crossed by tightly drawn, maze-like linear motifs. The low-contrast pattern has a graphic presence, while the woven surface gives the near-black shade subtle depth as it catches the light.

About this fabric

This heavyweight 585 gsm textile is well suited to upholstery, with a 140 cm usable width for covering substantial furniture pieces. Fine charcoal and muted grey lines form repeating angular pathways, creating a measured geometric rhythm rather than a bold, high-contrast statement. The pattern repeats vertically every 16.5 cm, allowing the motif to be positioned neatly across upholstered panels. With 65 threads per centimetre, the closely constructed weave reinforces the composed, tailored appearance of this Onyx colourway.

How to use it

Pair the deep charcoal tone with warm timber, brushed metal or soft stone upholstery for a sharply tailored scheme. On larger seating, let the restrained grey linework provide pattern while keeping the overall room feeling dark, calm and architectural.

Use this deep charcoal geometric weave on tailored seating, where its quiet contrast adds structure without overwhelming the room.

A pattern needs somewhere for the eye to rest, so these are the plains and textures that sit beside Concept Onyx without fighting it. Mixed across the houses we hold, which is the part a single supplier's book cannot do.

Paint that goes with it

Two ways to take the room. Both colours are from houses we hold, so a pot can come off the same order as the cloth. Screens shift colour, so treat these as a direction and bring the cloth to the shelf before you buy the paint.
