Compatible Spare Parts & Extensions for USM Haller® Systems

A modular furniture system should never become obsolete—it should evolve with you.

If you already own a USM Haller® system, there’s no need to replace it simply because your requirements have changed. Compatible components provide a practical and cost-effective way to expand, repair, or customise your furniture while preserving the flexibility of modular design.

The DERLOOK CMS Collection includes compatible components designed for use with existing USM Haller® systems, helping extend the life, functionality, and versatility of modular furniture.

Extend Your Existing System

One of the greatest advantages of modular furniture is its ability to adapt over time.

Whether you’re furnishing a new home, redesigning your workspace, or simply creating additional storage, compatible components make it easy to expand your existing system without starting from scratch.

Popular upgrades include:

• Adding additional shelves
• Increasing the width or height of a unit
• Creating larger TV units or sideboards
• Converting open shelving into enclosed storage
• Adding cable management or internal dividers
• Reconfiguring existing layouts to suit new spaces

Because every modular system is designed with flexibility in mind, your furniture can continue to evolve alongside your lifestyle.

Compatible Replacement Components

Individual components may occasionally become damaged, misplaced, or require replacement after years of everyday use or relocation.

The DERLOOK CMS Collection includes a wide range of compatible replacement components, including:

• Steel panels
• Chrome tubes
• Connector balls
• Shelves
• Drop-down doors
• Internal dividers
• Assembly hardware

Replacing only the components you need is an economical way to restore your furniture while extending its service life.

Compatible Accessories & Custom Solutions

In addition to replacement components, DERLOOK offers a range of compatible accessories and custom solutions that allow you to personalise and expand your modular furniture.

Available options include:
