ᐅ KALLAX is More Wobbly After Moving – Why Is That?

Hello everyone, I recently rearranged my IKEA KALLAX shelving unit because I changed the room layout. I noticed that the shelf is now significantly wobblier than before, even though I did not use any new screws or fasteners.

My specific question is: Why is my KALLAX shelving unit wobblier after being moved, even though the components seem unchanged? What mechanical or structural reasons could cause the shelf to lose stability simply by being relocated? I would appreciate a detailed explanation, especially considering the assembly method and material properties.

Thank you in advance!

This is usually because the fasteners have loosened after moving it. Check the screws and tighten them if necessary. The floor surface can also have an effect, especially if it is uneven now.

I find the explanation of loose screws too simple.

. Have you checked the connection points thoroughly? Often the cause is more complex:

IKEA furniture like the KALLAX is designed to maintain stability through the connection of individual parts at precise assembly points. When the shelving unit is just moved, the surface underneath may differ, leading to changed pressure or a different load distribution. Additionally, the unit might have been slightly deformed or twisted during the move—which, considering the relatively thin material of the KALLAX, can cause wobbling.

How exactly did you place the shelving unit? On a flat surface or carpet? If the floor is uneven, the legs cannot rest evenly, which creates movement.

That describes it very well.

Basically, the KALLAX shelf is a lightweight construction, especially when it is not attached to the wall. When moving it, the individual parts may no longer be perfectly parallel to each other, which reduces stability.

It is always recommended to fix the KALLAX to the wall, as this makes the entire structure more rigid. The joints in the plug-in and screw connections are not necessarily damaged by moving it, but if the shelf stood perfectly level before and now wobbles slightly, the play can increase.

A tip: also check the feet to ensure they are fully resting on the floor and that no small shims (washers or felt pads) have slipped out of place. Sometimes this is not immediately noticeable.
