Hello everyone,
I am currently planning to reinforce my KALLAX shelf unit, as I mentioned that it can sometimes wobble under heavier loads. I came up with the idea of stabilizing the frame additionally using aluminum profiles.
Have any of you already tested stabilization solutions with aluminum profiles on the KALLAX? I am particularly interested in how you implemented it, which profiles you used, how you attached the profiles to the furniture, and what effect you achieved.
It would also be great to know whether the effort is worthwhile or if there might be other effective and simple alternatives to make the cabinet more resistant to bending.
I appreciate any constructive advice!

Are any reinforcements or special connection techniques necessary here to prevent long-term deformation or even loosening of the screws?This is also an important point for me. So far, I have mainly considered simply screwing the profiles through the back panel, but the back panel is usually just thin hardboard and certainly not very strong.
Therefore, I am looking for methods to attach the profiles either directly to the wood of the sides or the base, in order to create load-bearing connection points.
Does anyone have experience with how to do this well using standard KALLAX units, without making the assembly too complicated? I am also interested in advice on the appropriate screw size and whether it makes sense to use additional wooden strips as a backing.
From a technical perspective, it is correct that the back panel of the KALLAX, being a thin hardboard, does not effectively support loads from aluminum profiles. Therefore, I recommend the following approach:
1. Attach the aluminum profiles not only to the back panel but reinforced on the inside of the side panels using continuous drilling and suitable anchors or direct screw fastening.
2. Use wooden strips (e.g., spruce strips measuring 20x20 mm (0.8x0.8 inches)) inside the cabinet, fitted between the side panel and the bottom/carcass to provide a stable base for the profiles.
3. Instead of standard Phillips screws, use countersunk screws with a minimum diameter of 4 mm (0.16 inches) to ensure long-lasting stability.
4. Pre-drill holes with a slightly smaller diameter than the screws to prevent splitting the wood.
These measures significantly improve the connection and distribute the load more evenly. Without such reinforcements, heavy loads can cause the attachments to loosen quickly.
Fjum10, if you want load-specific values, I can also offer advice on loads and their distribution.

In addition to the good advice already given, I can add the following:
For sustainable stabilization, I recommend using aluminum angle profiles, which are attached to the inner edges (corners) of the KALLAX shelf.
These angle profiles simultaneously increase vertical and horizontal rigidity, preventing both edge deformation and lateral wobbling.
In my opinion, a combination of profiles on the back panel as well as on the corners provides the best stiffness for the piece of furniture.
Additionally, screw connectors could be combined with hardwood battens to make the connection permanently load-bearing. However, I would only do this if you plan to use the furniture for very heavy loads.
