ᐅ KALLAX shelves no longer stay securely in place after moving

Hello everyone, I have a problem with my KALLAX shelves from IKEA after moving. Previously, the shelves fit perfectly in the compartments and held firmly. After setting it up in the new location, I noticed that the shelves no longer fit tightly. They wobble a bit and sometimes even slide out if you’re not careful. In my opinion, the structure of the shelf hasn’t changed; I assembled it very carefully.

Could it be that the groove or the shelf unit itself has warped? Or is there a specific way to position the shelves to ensure they fit tightly again? I am not using screws to fix them in place, as far as I know KALLAX doesn’t require that – the shelves are simply inserted.

Has anyone else experienced something similar? Maybe you have a solution? Thanks in advance for your tips!

Hi albert-pin, I’m familiar with this issue from a friend who assembled their KALLAX shelf after moving. 😊 Often, it’s caused by slight warping of the side panels, which can easily happen during transport. The shelves actually rest only on small support ledges that sometimes give a little or feel slightly loose due to minor distortions.

My advice: Check if all the side panels are truly flat and aligned. A small adjustment during assembly can make a big difference. Also, very thin strips of foam or felt at the support points can help if the wood has slightly shrunk or expanded in width.

Good luck, you can do it! 🙂

Kallax shelves no longer fit snugly? First, check if the sides of the shelving unit are warped. Assemble the unit in a different location on a level floor. If the groove of the supporting strips is damaged, felt pads can help.

The shelves will only fit loosely if the support strips are damaged or bent. There are no screws in KALLAX, only supports, as mentioned before. It’s possible that some areas were scratched during transport?

Hello albert-pin, I understand that this is frustrating. The KALLAX shelving unit is undoubtedly sturdy, but the shelves are simply laid in place and are held by precise measurements and the edges of the frame.

One possible cause could be a slight deformation or shift during transport and assembly. It can help to set up the unit on a flat surface and make sure all corners are square.

Sometimes, it helps to briefly remove the shelves and lightly sand or clean the surfaces of the support strips to prevent dust or paint residues from interfering.

If applicable, please let us know whether you have assembled the unit multiple times or if this is your first time setting it up at the new location, as that information could be useful.

Thank you for the suggestion. This is indeed the first time I am assembling it on site. I have used the shelf for several years at my previous residence without any issues. It was carefully disassembled and transported. I did not notice any visible damage, neither on the side panels nor on the support strips. Of course, I cannot rule out that its shape may have changed due to humidity, temperature, or stress.

Can such changes happen that quickly? Are there specific material properties in Ikea KALLAX that might cause this kind of reaction? Perhaps the colors or surface treatments are relevant in this context?
