Hello everyone,
Some time ago, I used an IKEA Kallax shelving unit to organize my LEGO bricks and sets systematically. The idea was to fill the individual compartments well with sorting boxes or bags—mainly smaller bricks but also some larger, heavier pieces. Unfortunately, after a few weeks, I noticed that the middle shelves in the compartments had noticeably sagged, and in one area even torn, which I attribute to the load. I wasn’t even extremely overloading it; I would estimate the weight to be about 8–10 kg (18–22 lbs) per compartment.
So, my question is: Has anyone had similar experiences with the Kallax shelving unit in the context of LEGO organization? How much weight can the shelf actually support, and are there any tips or solutions to permanently counteract these stresses? On the internet, there are very different opinions regarding its stability and load capacity. Thanks in advance for your feedback!

To keep the shelf stable over the long term during LEGO sorting, it is essential to adjust the load distribution.
This is exactly where the problem lies. For shelves with thin boards, it is important that the load is distributed as evenly as possible over a large surface area. In practice, this means:
- Use wide supports under small boxes (such as sturdy boards) so that the individual containers do not rest on the shelf board at single points.
- Check the maximum load per shelf and aim for the lower end of the specified range to avoid permanent heavy loads.
- Alternatively, arrange heavier items in the lower shelves during sorting, as the load is better supported there.
- For heavier sets, freestanding shelves made of metal or solid wood are a good alternative.
Technically, the Kallax is furniture intended for light to medium weight. For permanently heavy loads, renovation or an upgrade of the shelving system is necessary.
I also recommend occasionally checking the shelves for initial deflection and taking corrective action in time.
