ᐅ My Kallax unit tips over when only one side is loaded – is this normal?

Hello everyone,

I have an issue with my Kallax shelving unit from Ikea that’s causing me some concern. When I load the shelf only on one side, for example, just the left or right side with books or other items, the unit tilts slightly toward that side. This happens even when the total weight isn’t very high—the other side is basically empty or almost empty. My question is: Is this tilting normal for Kallax units because the design is relatively lightweight and open, or does it indicate an assembly problem or instability?

I’m aware that the shelf is not a heavy-duty piece of furniture, but I expected that even with this noticeable tilting effect, the whole unit would still remain stable enough. What are your experiences with Kallax in these situations? Are there any tips or additions to minimize this issue without significantly changing the appearance of the unit?

Looking forward to your opinions and thanks in advance for any tips or shared experiences!

This sounds like a classic beginner’s mistake – Kallax is modular and lightweight by design, not primarily intended for unbalanced loads. The furniture tips because it simply isn’t designed for one-sided loading.

One could argue that the user should ensure an even load distribution, but IKEA clearly states that the shelf is meant more for light storage than as heavy-duty furniture. By the way, the tipping issue isn’t just related to materials or construction, but also to the floor’s condition – it becomes even more noticeable on uneven floors.

However, if the Kallax tips significantly even with a light load, I would check whether all screws are properly tightened and if the back panel and base supports are correctly installed – these are often the cause of an unstable structure.

In short: no, the Kallax should not tip just because you load one side, but it can happen with extreme weight imbalance. Placing one side against a wall or securing the unit to the wall is a good idea.

Does the Kallax tip over when only one side is loaded? Yes, that is normal.

You can fix this by securing it to the wall or distributing the weight evenly on both sides.

It’s not an installation error, just the design principle.

The tipping issue with the Kallax shelf is technically understandable. The Kallax is a lightweight shelving unit with narrow side panels and a thin back panel, primarily designed for moderate loads. In fact, the tipping stability is low when loaded on one side only, as the center of gravity then shifts significantly outside the base area.

To improve stability, the following measures can be recommended:

1. Wall mounting: IKEA provides mounting kits that secure the shelf additionally.
2. Load distribution: Evenly loading the compartments prevents one-sided tipping.
3. Anti-slip mats: These help prevent sliding on smooth floors, which can lead to tipping.
4. Use of additional feet or floor leveling: Check if the floor is level, as small unevenness can allow significant movement with Kallax.

Conclusion: Tipping under one-sided load is not a construction fault but a design characteristic. Those seeking maximum stability should plan for wall mounting and load the shelf accordingly.
