ᐅ Kallax warped after standing upright – is there a chance to restore its shape?

Hello everyone,

I have a problem with my IKEA Kallax shelving unit, which I have stored upright for a few weeks. Unfortunately, I have now noticed that the unit has warped slightly – the back panel no longer sits flush against the wall, and some of the shelves appear a bit crooked or no longer perfectly rectangular. My question is: Is there any way to restore a Kallax shelving unit that has warped slightly after extended upright storage back to its original shape? Or is the warping irreversible because the material has permanently deformed?

Specifically, I have checked the back panel and side panels, which are made of pressed wood composite with a melamine coating.

I understand that load and moisture can play a role, but the unit has so far been stored dry and not overloaded. Does anyone have experience with whether such warping can be corrected by pressing it back, applying weight, or other methods, or should I prepare for a replacement?

Thanks in advance for any helpful advice!

My advice: Check whether the warp is still flexible or has become stubborn.

Thanks, that makes sense. I will try tightening it firmly.

Whether you try to reshape the current warp or not – my impression is that it depends on the definition of "original." Because the shape doesn’t just “disappear” on its own.

That also makes sense to me. I will disassemble the shelf and inspect the parts individually.

One more detailed question: Would it help to treat the shelf with targeted heat indoors (e.g., using room heating) to possibly release moisture? Or would that risk damaging the finish?

I’m grateful for any further tips!

That is basically not a bad idea, but be careful: excessive or rapid heating can cause the melamine coating to crack or peel. It’s better to warm the shelf slowly and evenly, avoiding direct heat sources aimed at it, and instead maintain a consistently warm and dry room.

A tip: use a dehumidifier to help keep the humidity relatively low and stable. Prolonged drying periods over several days reduce swelling.

And as mentioned before: loosen or remove the back panel while straightening the shelf.

I wish you good luck!
