Sonos CMF Guidelines

Global Standards & Implementation Framework

CMF Lead — Cross-Category / 2021-25

A unified CMF foundation across the Sonos product portfolio.

Context

The Sonos CMF Guidelines are a living document—a cross-category framework defining materials, colors, and finishes that ensure brand consistency while adapting to new products and technologies. Serving as both reference and evolving toolkit, it bridges design intent and implementation, supporting teams across multiple product lines and generations.

Goal

Develop a dynamic, flexible resource that balances coherence with adaptability, enabling teams to make informed CMF decisions while supporting new form factors, materials, and emerging technologies.

Approach

  • Material hierarchy: Defines priority and application across metals, plastics, and textiles, updated continuously as new materials are introduced.

  • Finish language: Specifies textures, gloss levels, and tactile qualities, refined as products and processes evolve.
