Hello everyone, I am currently considering extending my existing Kallax shelf from IKEA to use it as a desk in order to gain more storage and workspace. Has anyone here had experience with a project like this? I am especially interested in tips regarding stability, the best way to attach the extension, and which materials are suitable for enlarging the workspace without compromising the appearance or overloading the support structure. Additionally, I would appreciate any advice on ergonomic design and cable management if you have implemented this. Thanks in advance!

Kallax is basically a shelving system and not designed for table loads.

That is correct. IKEA itself does not recommend using Kallax as a base for tables. However, in practice, sufficient stability can be achieved by using sturdy plywood panels and improved support, for example, with additional Kallax units or strong legs.

Regarding cable management: a good solution is to install cable trays underneath the tabletop—this keeps cables neatly concealed and preserves the overall design.

Thank you, that confirms my previous considerations. Can anyone recommend specific fasteners that are particularly suitable? Or perhaps even a trick to prevent the panel from slipping without having to use too much visible hardware? I value a clean, neat appearance as much as possible.

High-strength adhesive strips can prevent slipping when used together with angle brackets. Additionally, small rubber buffers placed between the Kallax unit and the board provide extra stabilization and mild cushioning. This keeps the board securely in place without creating an overly technical appearance.

90-degree metal brackets, either galvanized or powder-coated depending on the color of the panel. Screws measuring 4x40mm (about 0.16x1.57 inches) used with a properly matched drill are sufficient. If the panel fits precisely, the connection will also be stable.

In addition to securing the panel, I recommend using so-called "table connectors" (for example, metal furniture fasteners), which are often used in furniture assembly. These provide a particularly strong, slip-resistant connection between the panel and the frame without the need for visible brackets.

For a harmonious overall appearance, it is advisable to adjust the color of the panel (e.g., painting or veneering) so that the extension blends seamlessly into the existing piece of furniture.
