Hello everyone,
I’m planning to stack two KALLAX shelves on top of each other and I’m wondering how stable the whole setup really is. The combination is mainly intended as a room divider and will occasionally support some weight—not extreme loads—but I do want to feel reasonably secure. In various forums, opinions differ: some say the two-unit setup is stable enough without additional anchoring, while others strongly recommend fixing it to the wall or adding extra support with brackets or even a shelf panel.
My question is: Does anyone have practical experience with the stability of two stacked KALLAX units? How high is the risk of tipping? Does IKEA provide any recommendations for combining two shelves from this series? If you have used such setups yourself, how did you improve the stability, and what loads do you consider safe? Thanks for your insights!

Regarding the stability of two KALLAX units stacked on top of each other, it should be noted that the system is primarily designed for single-unit assembly. The IKEA instructions do not include stacking unless the modules are additionally secured (e.g., wall mounting with brackets).
In practice, stability depends greatly on usage and load. Simply placing the units on top of each other poses a risk of tipping, especially with uneven loading or lateral pressure. As a general recommendation:
- Secure to the wall or use stability brackets between the modules,
- Do not exceed the maximum load limits specified by the manufacturer,
- Take leveling measures to compensate for uneven floors.
Without these precautions, there remains a certain risk, so I advise against stacking without proper securing.

I stacked two KALLAX units on top of each other without any brackets! 😄 It’s quite stable, but honestly, I didn’t leave it like that permanently. My trick was to put heavy items at the bottom and keep the top unit lightly loaded. If you do that, it stands well – no wobbling or anything.
Exactly, that’s the key point! Safety first, especially if there are children in the house. But for my simple storage needs, it has been absolutely fine so far 🙂

In addition to the previous information: When stacking two KALLAX shelves on top of each other, stability should always be ensured by using connecting elements. I recommend securing them with sturdy metal brackets that can be screwed between the two units. Additionally, the bottom unit should be placed on a flat and solid surface.
The maximum load capacity per compartment is approximately 10-15 kg (22-33 lbs), which should not be exceeded, especially for the upper shelf section. This reduces the risk of tipping.
Regardless of the connection method, I advise against stacking the units without attaching them to a wall, as the structure can easily shift or lose stability.

IKEA notes on many pieces of furniture that wall mounting is strongly recommended, especially for higher stacking. In my opinion, this is not just a “recommendation” but essential for safety, as tipping hazards can cause serious injuries.
Furthermore, the question arises whether ignoring the specified securing measures (i.e., a purely “freestanding setup”) could exclude insurance coverage in the event of an accident. It would be important to know. Does anyone have specific experience or reliable sources on this?
What is clear is that even with relatively light loads, the center of gravity shifts and the risk increases significantly as the units get taller. So, I would strongly recommend stabilization.

Thank you for the feedback so far; it’s already very helpful.
That’s a simple but effective measure, which I will probably rely on as well.
This is really important to me because I have small children at home. If I want to build without securing to the wall, I should at least know the legal situation.
Are there any reliable sources on how IKEA interprets this issue under German law? And are there alternative stabilization solutions that don’t necessarily require wall mounting but are still safe?
Looking forward to more opinions!
