ᐅ How can I build an IKEA Besta with adjustable compartments as a multifunctional piece of furniture?

Hello everyone, I want to convert my IKEA Besta shelving unit into a multifunctional piece of furniture with adjustable compartments. Specifically, I’m looking for advice on how to arrange the shelf sections so that I can later combine doors, drawers, and open or closed compartments in a flexible way—ideally so that everything can be easily reconfigured and adapted to different needs. Does anyone have experience with assembling this or tips on the best way to add or swap modular elements? Any advice on stability and possible additions to make the furniture more versatile would also be very helpful.

If I were you, I would first build the entire frame structure. Then you can insert the shelves flexibly and combine them freely with the Besta fronts. Make sure to use the holes for the adjustable feet and the mounting holes.

It is important to establish a clear grid from the beginning so that different elements like doors or drawers can be installed accurately later on. Generally, it is advisable to work with the standard dimensions of Besta components. This also makes future additions easier if the usage needs to change. I also recommend using sturdy side panels and, if necessary, internal frames to ensure the structure remains stable despite changes in the layout. Additionally, planning the back panel is crucial: it should be sturdy and precisely matched to the selected compartments.

A modular approach works best if you stick to the standardized height of the Besta elements. This way, you can easily replace compartments or swap doors later on.

Thank you, that sounds reasonable. Could you please explain in more detail how you work with the interior frames? I ask because I’m concerned the shelving unit might become unstable if the compartments are too large or vary too much in size.

The internal frames are basically additional reinforcements that you install inside the Besta frame. They reduce the span of individual shelves so they don’t sag. This is especially helpful for large adjustable compartments to ensure stability. Usually, you can use simple wooden edge profiles or metal brackets for this, which can be installed unobtrusively. This way, you can precisely adjust the height of the compartments and increase their load capacity.
