ᐅ IKEA BESTA DIY: How can I combine multiple units to build a large sideboard?

Hello everyone, I am planning to build a large sideboard using several IKEA Besta units, but I want to keep a few things in mind to ensure that the final result is stable, visually appealing, and functional. Specifically, I would like to know the best way to connect the individual modules so that no unwanted gaps appear and the sideboard can withstand stress, for example, when placed against a wall. I am also interested in the best approach for achieving a consistent front design and how to compensate for possible unevenness in the floor to prevent wobbling. Has anyone had experience assembling multiple Besta units and can provide tips on what to pay special attention to, which connectors are most suitable, and how to proceed in a structured way during assembly? Thank you in advance!

Hello Moritztu, your project is very interesting and can definitely be realized well with IKEA BESTA, as long as a few technical details are taken into account. First, regarding the connection of the modules: it is best to use special connector plates or brackets, either those offered by IKEA or suitable ones from brands like Häfele, to securely and stably join the individual BESTA cabinets. Be careful not to tighten the screws too much to avoid damaging the material.

A common issue with larger sideboards arises from uneven flooring – I recommend using height-adjustable furniture glides or feet to effectively compensate for any irregularities. For a uniform front appearance, it is advisable to choose either continuous doors or drawer fronts and ensure that all elements align perfectly flush.

It is also important to fix the modules to the wall to prevent the sideboard from tipping, especially with taller and longer constructions.

If you like, I can provide you with a more detailed step-by-step guide that I have tested myself.

I would like to add a brief guide here that can help you if you want to combine several BESTA units into a large sideboard:

- First, align the individual modules on a flat surface and check that the side panels are perfectly vertical.
- Use sturdy connectors, such as threaded inserts with matching screws or metal brackets, to securely join the modules. Distribute these evenly at several points, especially along the adjoining side panels.
- To avoid gaps, it is advisable to gently push the units together when connecting them and, if necessary, temporarily clamp them with clamps.
- For the fronts, always use a common rail or adjustable hinges so that the doors are perfectly aligned and close evenly.
- Any unevenness can be compensated with adjustable feet or floor leveling pads, ensuring the entire sideboard stands securely without wobbling.

I can confirm this; it really creates a calm appearance. If you have any questions about the fasteners or tools, just ask.

In short: Connect the modules with sturdy metal brackets.
Use adjustable furniture feet for the floor.
Make sure the fronts are even, ideally with matching doors or drawers.
This will ensure the sideboard stands firmly and looks good.

Does anyone have experience assembling multiple BESTA units together and can offer advice on what to pay special attention to, which connectors are useful, and how to approach the assembly in an organized way?

To answer your question in an organized manner:

- Connectors: The most efficient are threaded inserts combined with machine screws, which create a strong connection without damaging the carcasses. Alternatively, IKEA’s special connecting brackets provide an easy assembly method.
- Assembly: Start by precisely aligning a single unit on a level surface, then connect the modules together while frequently checking their alignment. Before final screwing, it is advisable to do a trial fit by slotting the parts together and making any necessary adjustments.
- Front design: For a modern, uniform look, continuous doors or drawer fronts are recommended. You can also individually paint or apply vinyl to certain fronts to achieve a cohesive appearance.
- Uneven floors: Height-adjustable feet or furniture glides from a hardware store compensate for differences and ensure stability.

I hope this structured overview helps you.
