ᐅ My KALLAX free-standing unit keeps developing new cracks on the inside.

Hello everyone,
A few months ago, I bought the KALLAX freestanding unit from Ikea and noticed that the inside of the shelf, especially the back panels and sides, keeps developing fine cracks. These cracks appear not only along the edges but also across the larger surfaces within the unit.
I’ve already made sure not to overload the shelf and to avoid placing it near sources of high moisture. However, the cracks still seem to be slowly increasing.
My question to the community: Has anyone experienced this issue? Could it be related to the material quality of the KALLAX, or might environmental factors such as temperature or humidity changes be causing it? Are there any preventive measures or repair tips to stop or reduce the cracking?
I look forward to your experiences and suggestions!

To improve stability, here is a brief guide:
1. Check the location: Avoid direct sunlight and placing it against cold exterior walls.
2. Humidity: Optimal between 40-60%. A humidifier can help during winter.
3. Apply protection: A water-based clear coat is discreet and protects against moisture fluctuations.
4. Repair cracks: Fill small cracks with wood filler, sand, and then repaint.
Common mistakes are placing it directly by windows or cold walls and skipping the protective coating.
If you follow these steps, the durability of your KALLAX should significantly increase.

Combination with protective coatings, or you use specially impregnated back panels from the hardware storeThanks, Davebla. Can you recommend a good alternative to the original back panels that I can install without much effort? I've never replaced shelf parts before, but I want to prevent the back panels from making the shelf less stable.
What do you mean by protective coatings? I've heard about clear varnish before—would that be similar to a colorless wood oil, or would they have different effects?

I’ve heard of clear varnish before, but is that comparable to colorless wood oil, or do they have different effects?Let me explain a bit more in detail: Wood oil penetrates the wood and nourishes it, making it more flexible and enhancing the grain, but it doesn’t provide real protection against shape changes caused by moisture or temperature.
Clear varnish, on the other hand, forms a solid protective layer on the surface that significantly reduces moisture penetration and stabilizes the wood. For interior particleboard, I therefore recommend clear varnish—preferably water-based, as it’s easier to apply and barely changes the surface appearance.
If you’re repairing cracks, you should first fill, sand, and then varnish, which can prevent many problems. If you have any questions about application, just ask.

Many thanks to everyone here; your advice has helped me understand the problem better, and I hope I can now reduce or at least gradually stop the cracking.
