Hello everyone,

I am currently looking into the assembly and stability of the IKEA Brimnes wardrobe and would like to ask a more specific question: What role do the screws actually play in the overall stability of this piece of furniture?

I understand that screws generally serve to connect and hold parts together, but with furniture like the Brimnes, which is made from relatively thin engineered wood panels, I wonder whether the screws act solely as connecting elements or if they also significantly contribute to stabilization—such as by preventing twisting or unwanted movement.

Additionally, I am interested to know if there are differences in the type of screws, their positioning, or the number of screws that directly affect stability, or if it is the combination of fittings and screws together that provides overall stability.

I would appreciate a well-founded assessment, ideally with a technical explanation or personal experience!

It definitely makes sense to consider the effect of screws not in isolation, but within the context of the entire connection system.

Interesting point, thanks for the suggestion! My assembly instructions include not only screws but also so-called metal brackets and anchors. Where would you say the main load is carried within the furniture? Do these brackets contribute more to torsional rigidity than the screws?

Screws are therefore not just simple connectors, but significantly contribute to the overall structure

That aligns with my hypothesis.

I would appreciate a more detailed assessment regarding screws versus fittings.

Regarding screws versus fittings in the Brimnes:

The screws primarily serve to join the individual panels, meaning they hold the piece of furniture together as a whole. The brackets and fittings, on the other hand, are designed to increase transverse and longitudinal rigidity, especially against twisting and tipping movements.

You can think of it like this:
- Screws provide shape stability in the basic structure
- Brackets and fittings give the furniture stability against lateral forces

This means that screws and fittings each ensure different aspects of overall stability. A deficiency in one cannot be fully compensated by the other.

In practical terms, both are important and should be installed properly to keep Brimnes stable in the long term.
