ᐅ After taking apart the furniture, my Kallax shelving unit loses its stability – any tips?

I recently assembled an Ikea Kallax shelf unit, which I had to take apart after a while and then reassemble in a different location. However, I noticed that after disassembling, the shelf no longer has its original stability. It wobbles noticeably more, feels less sturdy, and is generally less secure for placing items on it. I followed the assembly instructions correctly, but even after reassembling, it seems less robust than before.

Are there any specific tips for improving the stability of a Kallax after it has been taken apart and put back together? Maybe tightening screws, using different connection methods, or adding extra reinforcements? Or is the material simply too susceptible to repeated assembly and disassembly? I want to avoid the furniture becoming unsafe if possible. Thanks in advance for your advice!

This issue actually occurs quite often when furniture like the Kallax is disassembled and reassembled. The main reason is usually the weakening of the connection strength of the screws and dowels, which become less tight after being loosened and tightened multiple times.

My advice: Carefully check all connection points and, if possible, replace screws and dowels with new ones. Applying a small drop of wood glue to the dowels can also improve stability. Make sure not to tighten the screws too much to avoid damaging the material, but also not too loosely. Sometimes, reinforcing the corners with brackets during assembly can help make the shelf more stable in the long term.

Check if all the joints fit properly. If the dowels are loose, you can secure them with wood glue. Replace screws if necessary, or use longer ones. Sometimes, attaching small felt pads under the feet helps to prevent the shelf from wobbling.

Hello! I am very familiar with the issue of reduced stability after disassembly, which has also happened with several Kallax shelves. Although the Ikea instructions are good, the plug-in joints often become a bit loose after multiple assemblies.

In addition to the tips already mentioned, it can help to reinforce the joints with a narrow strip of double-sided tape before joining the panels – this increases friction and thus stability.

You should also make sure during assembly that the shelf is placed on a perfectly level surface to avoid wobbling. If you still disassemble and reassemble the shelf frequently, you might consider reinforcing it at certain points with metal brackets that are barely visible from the outside.

The crucial factor is the precise fit of the dowels. As soon as the holes become slightly worn out, the shelf loses a lot of stability.

One option would be to use new wooden dowels with a slightly larger diameter or to fill the holes with wood filler and, after drying, rework them.

I also recommend securing the screws with a thread-locking adhesive to prevent them from loosening.

That is a reasonable approach. Enlarging the dowel holes makes little sense if the fit is compromised. Alternatively, increasing the contact surface of the connecting elements is advisable to better distribute forces.

The stability also depends on the alignment of the shelf – check both horizontal and vertical positioning with a spirit level. Uneven floors can cause the shelf to become unstable more quickly.
