ᐅ Kallax shelves tend to sag, especially when loaded with books.

Hello everyone,

A few months ago, I bought a Kallax shelf unit from Ikea, mainly to store books. Unfortunately, I noticed that the shelves—especially the horizontal surfaces holding the books—start to sag significantly over time. According to the product description, the shelves are supposed to have a high load capacity, but in my case, they don’t seem to hold up in the long run. Has anyone experienced something similar or knows how to prevent this?

I’m particularly interested in whether there are reinforcing methods to better support the material or if alternative shelves or additional support braces might be useful.

Thanks in advance for your insights and suggestions.
