ᐅ KALLAX doors always pop open when closing – are better hinges needed?

Hello everyone, I have been having an issue with the KALLAX doors from IKEA for some time now: whenever I close the doors, they “pop” open slightly after a short while, even though the hinges seem to be installed correctly. This happens with both doors on a KALLAX 4x4 unit. I wonder if this is caused by the standard hinges used and if there are better, more stable alternatives that could prevent this problem? I would appreciate any tips on hinges that stay firmly closed and stable over time. Maybe someone has experience with alternative hinges or improvements that stop the doors from “popping” open? Thanks!

I know this problem well. Often, realigning the hinges or tightening the screws helps. If something is already damaged, replacing them with stronger concealed hinges can be useful.

Hello Sonfredric, your issue with the "jumping" KALLAX doors is actually a known problem. The standard KALLAX hinges are cup hinges with a spring mechanism, but they often reach their mechanical limits due to the thin inner side of the door and the particleboard base.

I recommend first checking all the hinge screws and gently tightening them, but not too much to avoid tearing the material.

If that’s not enough, there are hinges available with reinforced spring tension and sometimes an adjustable soft-close mechanism, which provide more stable closing force. Brands like Blum or Hettich offer good models that are often suitable for furniture with thinner wooden panels.

Alternatively, you can check if the frame or the door is warped, which increases tension on the hinge and strains the spring mechanism. Especially with KALLAX, which is produced relatively inexpensively, material tolerances cannot be ruled out.

What is the condition of your material? Are the doors still in their original state, or have you modified or repainted them?

Thanks for the tip! The doors are still original, but I had already moved and realigned the unit a bit – the warping could have happened because of that.

Are there any recommended models that are mechanically more robust but remain size-compatible? I prefer not to do too much modification, more like plug-and-play solutions.

Regarding the issue: The standard hinge supplied with KALLAX is a simple cup hinge with a spring, designed for lightweight interior doors. The spring tension is relatively low, which can explain why the door sometimes "pops open" when closing if the door frame is slightly warped or the mounting is not ideal.

Hinges from Blum (e.g., BLUM Clip Top BLUMOTION 110°) with higher spring tension and integrated soft-close damping are recommended. Although these are somewhat more expensive, they are more durable and stable.

It is important that the drilling pattern of the new hinges matches that of the KALLAX unit; otherwise, adapters or modifications to the door panel will be necessary. A complete replacement with butt hinges or recessed hinges is usually not advisable due to the material thickness of KALLAX.

Less recommended are cheaper universal hinge types without springs, as they tend to worsen the problem.

I can well imagine how annoying it is when the doors keep popping open. I experienced the same, and after a while, it really became frustrating because you couldn’t use the furniture properly. I think it’s good that constructive suggestions are already being shared here.

It might be worth checking carefully whether there is a combination of door warping and hinge spring tension. Often, it feels like the problem is only with the hinge, but the actual issue lies in the material or the assembly.

It’s also important not to get discouraged. IKEA furniture is often designed for self-assembly, and with a bit of patience, you can usually get it under control!
