ᐅ How sturdy are IKEA BRIMNES shelves under heavy load?

Hello everyone,

I am currently facing the challenge of finding a sturdy shelving system for my home office that maintains its shape reliably under heavy loads. Specifically, I am looking at the IKEA Brimnes shelves. The product description states a maximum load capacity of about 25 kilograms per shelf (55 pounds), which seems a bit low for my needs, as I plan to store heavy binders and electronic equipment on them.

My main question is: How stable are the shelves in the IKEA BRIMNES series over an extended period when subjected to loads significantly exceeding the stated capacity? Are there any long-term experiences regarding whether they bend, break, or if the entire structure might be damaged?

It would also be important to know if the load should be distributed evenly or if point loads (for example, a thick binder in the middle) could cause problems.

I look forward to your assessments and experiences!

The BRIMNES shelves are made of pressed wood with a thin coating, which limits their capacity for stable load-bearing. Exceeding the manufacturer’s specified load of 25 kg (55 lbs) per shelf typically results in sagging.

- Long-term experience shows that point loads in the middle of the shelf are the weakest spot, as this creates the highest stress there.
- Even load distribution improves stability somewhat but does not eliminate the fundamental material limitation.
- Reinforcements using additional center supports could increase load capacity but are not included as standard in BRIMNES.

For heavy items or electronics that often exceed 25 kg (55 lbs) per shelf, it is advisable to consider other options with more solid materials or steel frames, or at least to install additional reinforcements.

I can confirm this from my own experience. I use BRIMNES shelves in a small home office and originally stored quite heavy binders stacked on individual shelves. After a few months, the boards noticeably bent downward, which looked quite unsightly and also gave an impression of instability.

For me, this is a clear lesson: the supplied shelves are not suitable for loads exceeding 25 kg (55 pounds) long-term. If you absolutely need to store heavy items, I recommend either adding secondary shelves or extra supports, or choosing different furniture.

I also find the idea of distributing loads as evenly as possible sensible, as it reduces the stress on individual points of the boards.

This is common with BRIMNES shelves when the maximum load capacity is exceeded.

If you want to store heavy items:
- Add extra supports
- Distribute the load evenly
- Or switch to models with sturdier shelves

This will help prevent damage over time.
