ᐅ KALLAX crooked after assembly – design flaw or error?

Hello everyone,

I recently assembled a KALLAX shelving unit from IKEA and unfortunately noticed that it is noticeably crooked after assembly. I followed the instructions very carefully and handled all parts with care. The unevenness is so pronounced that doors and inserts do not fit properly, making the whole unit feel unstable.

So my question is: Is the problem inherent to the KALLAX system itself, such as the design or tolerances of the components? Or could this be a production or assembly issue that occurs frequently?

I would like to know if other users have had similar experiences and whether there are any specific tips for making the KALLAX unit perfectly level, or if some unevenness is to be expected with this model.

Thanks for your opinions and advice!

The back panel not being properly secured or installed unevenly is often the cause. Check whether the back panel is straight and that all screws are firmly tightened.

I can understand your frustration, Annigo. The same thing happened to me with the KALLAX, and I wondered whether the system allows too little tolerance for installation errors.

Sometimes it’s due to minor warping in the engineered wood, which isn’t immediately noticeable but later causes the shelf to lean. This can occur during manufacturing or as a result of moisture in the room.

At the time, I made simple adjustments—for example, placing small rubber pads under some feet and repositioning the back panel. It’s probably a combination of the materials, the subfloor, and the assembly process.

Keep at it; this is not an unsolvable issue. 🙂

A common issue: when dowels are inserted crookedly, nothing fits correctly afterward. Simply recheck the wood joints and insert the dowels straight.

Are there any common problem areas in certain components (back panel, side panels) or screw fasteners that frequently cause issues with KALLAX?

The back panel is often the weak point, especially in older models. It can become loose or not sit flush. When installed correctly, however, it provides significant stability as a reinforcing element.

I completely agree. That’s why proper installation of the back panel is the most important step for correct alignment.
