Hello everyone,

I am currently planning to install an Ikea Kallax shelf unit in my car to have more storage space and a more flexible solution for my gear in everyday use. However, I have found very few reports on this so far and wonder how others have done it—especially regarding secure mounting during driving, possible modifications to the Kallax for automotive use, and its overall stability while on the road.

Has anyone here already installed a Kallax in their vehicle? If so, how did you secure the shelf and which types of vehicles did you adapt it for? I am particularly interested in whether it is better to just place the shelf unit loosely or to fully assemble it and possibly add extra anchoring to prevent wobbling or even sliding.

Looking forward to your experiences and tips, including any advice on potential pitfalls or necessary tools/materials.

Hello Fafe58,

Some time ago, I also installed a Kallax unit in my vehicle, specifically in my panel van, to better organize the cargo space and have quick access to tools and materials.

Regarding the mounting, I strongly recommend not only fixing the shelf with screws but also securing it to the vehicle floor or sidewall using angle brackets or metal strips. Simply assembling the Kallax elements is not enough, as the vibrations in the vehicle can cause it to wobble, which over time leads to material fatigue.

An important step is to sand the shelf thoroughly and treat it with a protective finish before installation, since moisture can build up inside the vehicle due to condensation. I also modified the back panel of the shelf by attaching a thin plywood sheet to increase stability and distribute the mounting points more effectively.

As for the vehicle type: depending on the width of the Kallax (usually 42 or 77cm (17 or 30 inches)), it is crucial to measure the installation space inside the vehicle precisely. My panel van has very limited space, so I chose the 42cm (17 inches) Kallax and secured individual compartments with sturdy metal baskets to prevent shifting inside the cabin.

If you are unsure about which mounting materials to use, I can recommend:
- Heavy-duty angle brackets made of galvanized steel, at least 3mm (0.1 inch) thick
- Screws of appropriate length with locking nuts
- Rubber buffers under the shelf to avoid contact with the vehicle bodywork

What is your exact vehicle configuration? I might be able to give you more targeted advice.

Best regards!

That’s a good point, although I wonder if this is realistic without major modifications to the vehicle, especially for rental or leased vehicles.

Before firmly anchoring the shelf myself, I would definitely check whether this could cause insurance issues in the event of damage (accident). Furniture installed permanently in a vehicle is certainly different from loose items.

Additionally, it’s worth considering whether the stability of the Kallax is sufficient if it gets propelled forward during sudden braking. The thin particleboard panels could be a potential weak point.

Does anyone have experience with how the Kallax performs in crash tests or under similar stresses, or is this more of a DIY solution with inherent risks?

The question about crash safety is absolutely valid, and it must be clearly stated: The Kallax shelf unit is designed as household furniture, not for automotive use with the highest safety requirements. On one hand, the materials are not certified for high-impact forces, and on the other hand, there is no testing standard that covers vehicle applications.

That said, if the unit is properly secured with suitable fastenings that transfer loads downward into the vehicle structure and additionally fixed with tie-downs or nets, the risk can be significantly reduced. Some users have also added foam padding or edge protection at vulnerable points to reduce the risk of injury.

What I recommend is careful planning regarding what loads will be placed on the shelf and how often the vehicle is used in urban traffic or possibly off-road conditions. The smaller and lighter the individual shelves are stocked—and the better the entire system is secured—the more practical the compromise becomes.

If you are looking for simple storage for occasional trips, the Kallax can be a practical solution. For more demanding outdoor equipment or heavy loads, I would suggest opting for specialized vehicle conversions instead.
