Hello everyone,
I plan to store several very heavy boxes (about 25-30 kg (55-66 lbs) per box) in the IKEA KALLAX shelving unit. My question is: What is the best way to safely secure such heavy boxes or crates in the KALLAX so that they stand firmly, do not slip, and the shelving itself does not get damaged?
I am especially interested in which methods or additional aids you use to prevent the boxes from tipping over or shifting sideways. Tips for custom-built solutions or modifications for the KALLAX would also be very helpful.
I look forward to your experiences and advice!

Hello Pra-dan,
I find your question very interesting, as the KALLAX is basically designed as a simple shelving unit and not necessarily for loads in the weight range of 30 kg (66 lbs) per compartment. Here are some detailed thoughts on this:
1. Load capacity: A single KALLAX shelf normally supports a maximum of about 13-15 kg (29-33 lbs), according to IKEA’s specifications. So at 25-30 kg (55-66 lbs), you are clearly above that. This means the entire shelving unit needs to be reinforced or additionally supported.
2. Securing the boxes: To prevent slipping, non-slip mats made of rubber or silicone are especially suitable. You place these directly on the shelves. This increases friction.
3. Strapping or locking in place: One option is to fix the boxes within a compartment using straps or hook-and-loop fasteners. This helps prevent them from falling out or sliding sideways.
4. Additional supports: If you do not want to reinforce the shelf itself, you can build a kind of enclosure with wooden or metal strips at the back or sides inside the compartments, so the boxes cannot physically slide out sideways.
5. Reinforcing the shelves: A very important measure is to strengthen the shelves themselves. The thin particleboard of the KALLAX is not primarily intended for heavy loads. It is worth attaching extra boards underneath or installing slim metal brackets as supports.
6. Location safety: The shelving unit should definitely be secured to the wall to prevent tipping over when loaded or subjected to slight force.
What does your spatial situation look like exactly? Are the boxes moved frequently, or is the unit in a quiet spot? I ask because that affects the requirements for securing them.
Best regards!

Hello Pra-dan,
I’d like to add some points and cover a few basics, especially if you plan to take the boxes in and out frequently.
1. Before securing the boxes, you should check how much weight the shelving unit can actually support. Sometimes it helps to reinforce the shelf with an additional wooden board (e.g., plywood, 12 mm (0.5 inch)) to add stability and prevent sagging.
2. If the boxes will mostly stay in place, you can use brackets or small metal strips on the back of the shelf to prevent the boxes from sliding too far backward.
3. Using non-slip mats (available at most hardware stores) inside the individual compartments is very useful — they increase friction between the shelf and the box.
4. Sometimes a simple anti-tip device on the shelving unit can be sensible, especially if the weight is unevenly distributed. IKEA offers suitable brackets for screwing into the wall.
Please note that KALLAX is a modular series, and if you’re using multiple units, you should connect the individual elements securely to each other.
If you like, you can also describe what type of boxes you’re using — what material they’re made of and whether they have handles — as this can also influence how you secure them :-)

That's brilliant, so many options! 🙂
I just secured my heavy boxes to the carcass with wide Velcro straps – it holds great and opens quickly! I also placed simple rubber mats under the boxes, and since then everything has been rock solid.
And don’t forget: Always screw the KALLAX unit itself to the wall! Safety first!
Good luck, you’ll definitely manage it! 🙂

I’m honestly wondering: How stable is the KALLAX really under such loads?
This means that if each box is expected to hold 25-30 kg (55-66 lbs) easily, it will be a constant overload. The question isn’t just how to secure the boxes, but whether the shelf can support that weight long-term without losing stability.
Therefore, I would suggest installing a stronger shelf panel and placing the whole unit on a more robust substructure. In my opinion, just securing it on top is not enough.
What about considering alternative shelving systems? Or are you thinking about modifying the KALLAX with solid wood shelves or metal reinforcements?
