Hello everyone,
A few months ago, I modified and expanded a KALLAX shelving unit from the IKEA range according to my ideas – unfortunately, one of the components has since become loose, meaning the joints are no longer stable, and the shelving wobbles significantly more than before. This concerns the modular extension with several shelves and the additional interior frame that I attached with wood screws.
I am particularly interested in finding out what options exist to reinforce KALLAX modules afterwards or to fix loosening issues, especially when modifications with additional fasteners have been made. Are there proven repair techniques or specific materials that are recommended?
I want to avoid buying a completely new shelving unit and am looking for practical solutions that also handle the structural load. I am very much looking forward to your tips and experiences!

Hello hubertgo,
I can understand how frustrating it is when a system like KALLAX, which should be sturdy, suddenly loses stability after such modifications. It sounds almost as if the original joints were weakened due to the extra load.
One idea might be to reinforce the corners with small brackets or metal connectors—these are often discreet and can be attached from the back. I also recommend applying wood glue at the screw points, which adds extra strength once it dries properly.
What type of screws did you use? Sometimes the quality of the screws or the wood can also be a factor. Keep your spirits up; with a few tricks, this kind of issue can usually be resolved quite well! 🙂

Hello hubertgo,
to address your issue from a more technical perspective: loosening or sagging in KALLAX after modifications usually occurs because the slat joints and the thin particleboard give way under prolonged stress or additional alterations. Here is a brief step-by-step guide for repair and reinforcement:
1. First, it is advisable to loosen the screws and, if necessary, slightly enlarge any existing pilot holes to refill the old screw holes—for example, with wood filler or wooden dowels plus wood glue.
2. Then you can use new screws instead of the old ones. Important: choose screws with a larger diameter but not too thick, as this could cause the wood to split.
3. Metal brackets on the back or inside of the joints help a lot. Make sure that they connect not just two but preferably three points, as this effectively absorbs the leverage forces.
4. If possible, you can additionally install a thin plywood panel where the sagging is most critical—for example, as a reinforcement plate within the inner frame.
My question to you: Is the shelf subjected to heavy loads permanently (e.g., books, appliances) or rather moderate? Also, what exact modifications have you made? Have you possibly used different materials than the original KALLAX?

Hello hubertgo,
From a technical perspective, the main issue with KALLAX is often the quality of the particle board, which can deform under load and frequent stress, causing screw holes to enlarge.
For repair, I recommend the following steps:
- Remove the old screws and fill the holes with wooden dowels or a mixture of wood glue and sawdust.
- After the filler has fully dried, reinsert screws with a larger diameter and self-tapping tips.
- Use small metal brackets for internal reinforcement, especially at critical edges.
- Check the screws for corrosion and replace them with stainless steel versions if necessary.
Avoid overtightening the screws, as this can cause the wood to chip. The goal is a stable connection without overstressing the wood structure.

Additionally, you can drill elongated holes instead of round holes in the reinforcements, to allow some movement during expansions and prevent stresses from concentrating on brittle chipboard.
