ᐅ What connection options are available for additional shelves with the IKEA BRIMNES system?

Hello everyone, I am planning to expand my IKEA Brimnes shelving system and am looking for detailed information about connection options for additional shelf units.

Specifically, I am interested in what possibilities exist for attaching extra shelves or modules beyond the standard BRIMNES units.

Is this achievable with IKEA-original accessories, or would modifications or compatible products from other series be more practical?

What about stability and mounting, especially when adding multiple extra shelves?

I look forward to your experiences, tips, or advice, especially if anyone has successfully used specific connectors or fastening methods.

There are no official extension modules for BRIMNES, but you can attach other shelves using metal brackets.

The best stability is achieved by using enough screws and wall anchors.

Shelves from other IKEA series sometimes fit, but you need to pay attention to the measurements.

Great question! 😊 I extended my BRIMNES myself by simply adding extra boards with angle brackets – it worked perfectly!

It’s important to use high-quality brackets and screws. That ensures a strong hold and also looks neat! Have fun with your project, you’ll manage it!

To expand IKEA BRIMNES shelving systems, I recommend the following approach:

- First, measure the dimensions of your existing shelves carefully. BRIMNES components have standardized hole spacing for the shelves, which you can use.
- To attach additional shelves, you can use metal brackets that you screw to the side panels. Make sure the brackets fit the depth of the shelf boards, usually 30–40 cm (12–16 inches).
- There are no official IKEA add-on parts specifically for BRIMNES, but shelf supports and perforated panels from other series might be used as a base, as long as the dimensions match.

Common mistakes:
- Choosing brackets that are too small, which reduces load capacity.
- Screwing in the wrong positions—always consider load distribution.

My tip: Document all measurements before purchasing to select materials that don’t require rework. This way you can avoid unstable constructions.

A very good and practical description. I would like to add that the BRIMNES series is not designed internally for modular expansions and does not include support systems for additional attachments.

Therefore:

- Additional shelves should always be combined with a solid wall mounting.
- Alternatively, accessories from other IKEA series (e.g., Ivar or Algot) designed specifically for modular expansions can be used.
- However, this usually requires adjustments to the appearance and dimensions.

For the stability of the extensions, a load-bearing wall connection is always essential.

I recommend angle brackets or metal connectors from a hardware store. Simply attach them to the side of the BRIMNES and then place the shelves on top.

Don’t forget wall anchors for stability.
