ᐅ If overloaded, the KALLAX compartments can become warped or misshapen – has anyone experienced this?

Hello everyone,

I have a KALLAX shelf unit from IKEA in my apartment, which I mainly use for storing books and decorative items. I recently noticed that some of the compartments are starting to warp noticeably due to excessive weight – they look crooked, almost as if the shelves are bending and the sides are no longer standing straight.

Has anyone experienced something similar when these KALLAX compartments are filled too much or loaded too heavily? I am particularly interested in whether this is common with normal use or if I might already be reaching the load limits specified by the manufacturer.

Additionally, it would be helpful to know if there are any technical or practical solutions to prevent this leaning – for example, by reinforcing the shelves or using a different method of load distribution.

Looking forward to your insights and advice!

That sounds like a very common problem. I have a KALLAX myself that started to warp after a few months because I stored my books in it rather randomly and didn’t distribute the heavy ones evenly.

I will move the heavy books to the lower compartments.

That’s a good decision and can really make a difference. I was also hesitant to fix the shelf to the wall because I didn’t want to upset my landlord. But I did it anyway, and since then I’ve felt much more secure and there’s been no more tilting.

If you’re unsure about reinforcement, you could try just rearranging the books first. Sometimes that alone is enough.

Does anyone need tips on how to safely secure the shelf to the wall? I’d be happy to help. 🙂

Great to see so many good ideas already gathered here!

I love my KALLAX shelves, they’re really practical and stylish – but yes, if you overload them, they do tend to bend.

I can totally agree with that! Wall mounting really keeps everything stable, plus it feels safer when kids or pets are around the shelf.

And if you store the heavier items on the lower shelves and reinforce the compartments with support panels, you’ll be on the safe side.

Go for it, it’ll be great! 🙂

Additional tips:
- Distribute books evenly across multiple shelves.
- Reinforce shelves with wooden strips at the front and back.
- Address any damage promptly to prevent further issues.

If you want a certain look, you can also cover the board with white foil or paint it

Thanks again for the tip! Yesterday, I contacted a few timber suppliers about suitable MDF boards that I can mix and cut to size. I want to keep the shelf as close as possible to IKEA’s original design, so these kinds of solutions are important to me.

Distribute books evenly across several compartments

I’m going to redistribute the books more evenly now—I was probably a bit careless in handling. The compartments always seemed very stable to me, so I was all the more surprised when I noticed the deformation.

Are there any recommendations on how quickly deformations can be detected before they become a problem? Especially when using the shelf to store books, it can sometimes be difficult to assess.

Check the floors from below and from the side to see if they are sagging or if the edges are misaligned. If gaps appear at the joints or the shelf wobbles, it is definitely overloaded.

If there is slight sagging, respond early by reinforcing the shelves afterward or rearranging them.

I reinforced the back panel of my KALLAX with a thin plywood sheet and clamped it from behind. Since then, everything stays straight, even with many books.

This maintains the structure and prevents warping. It’s inexpensive and quick to do.
