Hello everyone,

I am planning to build an IKEA Besta combination where I mix different module widths. For example, one unit with a width of 60cm (24 inches) next to another with a width of 40cm (16 inches). My question is, what is the best technical approach to securely connect these modules so that they are stable and look cohesive? Are there specific connectors or techniques I should be aware of?

Additionally, I am curious if there are any limitations when using different module widths, such as for installing doors, drawers, or top panels. Are there recommendations for the assembly order to ensure the cabinet does not wobble or come apart later?

Thanks in advance for your advice!

You can connect different panel widths using the original IKEA connectors. It’s best to use the metal connector plates designed specifically for Besta. It’s important that the back panels provide overall stability.

You need to purchase doors and drawers that fit the respective module width. Usually, combining the 60cm (24 inches) and 40cm (16 inches) options works best.

Hello Tekileo,

I think your question is very well formulated, and I would like to give you a more detailed answer, as the combination of different Besta widths often causes confusion.

Basically, IKEA Besta is modular, meaning individual carcasses with widths of 60cm (24 inches), 40cm (16 inches), and 80cm (31 inches) can be placed side by side. IKEA provides sturdy metal brackets and connectors to secure the carcasses together from the inside.

When mixing widths, it is very important that all elements stand on exactly the same floor level; otherwise, the cabinet may wobble. A spirit level and, if necessary, small shims help create a stable base.

Doors, drawer fronts, and other fittings must be chosen to match the width (for example, 60cm (24 inches) doors for a 60cm (24 inches) carcass).

For assembly, it is best to follow the basic instructions for a single carcass first, then connect multiple modules. The back panel, acting as a cross brace, is crucial for stability, especially with longer combinations.

If you can also secure the entire unit to the wall, even better – this will prevent tipping for sure.

I hope this helps you!

It’s interesting that most people here consider the IKEA connector sets as the sole solution.

These connections hold up for shorter units, but depending on the construction, additional reinforcement should be considered—especially if there is load on the drawers or heavy appliances placed on top. Often, alternative screw connections or stronger concealed brackets are used here.

Furthermore, I wonder how practical it really is to place modules of different widths directly next to each other when floor unevenness also plays a role. A frame structure made of wooden battens connected to the carcasses can provide extra stability and compensate for irregularities.

What do you think about this kind of solution? Is the standard IKEA assembly really sufficient in all cases?

The question about stability with different frame widths is certainly valid.

I can only confirm that the original connectors from IKEA work well if the surface is level and the back panels are mounted properly. The back panels are crucial because they prevent lateral twisting.

If you have an uneven floor or are stacking multiple rows, I would recommend adjusting the lower modules to be height-adjustable and securing them to the wall – this way, the entire assembly is stable.

Regarding assembly: first, fully assemble all individual boxes, then connect them with the connectors, and only after that, insert the back panels. This method works best.

That sounds reasonable, thanks. I also want to place a TV and other electronics on the unit, so stability is really important to me.

Are there options for reinforcement that don’t require major visible modifications, like using brackets that can be hidden inside? Or do the IKEA connectors actually fit well in there?

– do you mean the thin boards nailed on from the back? Or the thicker furniture backing panels?

What are your experiences with connecting modules of different depths? I’m planning to combine some modules that are 40cm (16 inches) deep with others that are 60cm (24 inches). Is that usually possible without issues?
