How to Assemble Modular Furniture: A Step-by-Step Guide

Assembling modular furniture like USM Haller or Klackjoy might seem daunting at first, but with the right approach, it's a surprisingly straightforward process. This guide will walk you through everything you need to know.

What You'll Need

Before you begin, gather these tools:

Allen key / Hex wrench (usually included)
Rubber mallet (optional, for stubborn connections)
Soft cloth (to protect surfaces)
Level (to ensure your furniture is balanced)
Measuring tape

Understanding the Components

1. Ball Connectors (Nodes)

The iconic chrome-plated brass balls that join everything together. Each ball has 6 threaded holes arranged at 90° angles.

2. Tubes

Chrome-plated steel tubes in various lengths:

350mm — Standard height between shelves
500mm — Extended height option
750mm — Standard width

3. Panels

Powder-coated steel panels that form the surfaces:

Side panels
Back panels (optional, for closed units)
Shelves
Doors and drawers (for closed storage)

Step-by-Step Assembly

Step 1: Plan Your Layout

Before touching any components, visualize your final design. If you used our 3D Configurator, print out or save your design as reference.

Step 2: Create the Base Frame

Connect four ball connectors with horizontal tubes to form a rectangle
This creates the foundation of your first cube
Ensure all connections are hand-tight initially

Step 3: Add Vertical Tubes

Thread vertical tubes into the top holes of your base balls
For floor-standing units, attach leveling glides or castors to the bottom

Step 4: Complete the First Cube

Add the top layer of ball connectors
Connect them with horizontal tubes
You now have a complete structural frame

Step 5: Insert Panels

Slide panels into the grooves formed by the tube framework
Panels simply rest in place — no additional fastening needed
For back panels, insert them before completing the cube

Step 6: Expand Your Design

Continue adding cubes by sharing ball connectors
Each new unit shares one vertical face with the existing structure
This is the beauty of modular design — infinite expandability

Pro Tips

Tip 1: Work on a Soft Surface

Lay down a blanket or carpet to prevent scratching chrome components.

Tip 2: Don't Fully Tighten Until Complete

Keep connections finger-tight until the entire structure is assembled. This allows for small adjustments.

Tip 3: Use the Right Torque

Ball connections should be snug but not over-tightened. Over-tightening can damage threads.

Tip 4: Level as You Go

Check for level after completing each layer. It's much harder to adjust later.

Troubleshooting

Panels won't fit? Check that tubes are properly aligned. A slight misalignment can prevent panel insertion.

Structure feels wobbly? Ensure all connections are evenly tightened. Add back panels for additional rigidity.

Chrome scratched? Minor scratches can be buffed with chrome polish. For deeper scratches, replacement components are available.

Disassembly & Reconfiguration

One of the greatest advantages of modular furniture is reconfigurability:

Simply reverse the assembly process
Components can be reused indefinitely
Easily adapt your furniture as needs change
