ᐅ Ikea BESTA – How do I build a combination of open and closed units?

Hello everyone, I am planning a custom furniture project using the Ikea Besta system and would like to create a combination of open and closed elements. My idea is to build a shelving unit that includes open compartments for decoration or frequently used items, as well as closed cabinet doors for hidden storage. I have a few questions, especially regarding practical installation, material compatibility for the doors, and the optimal arrangement of the modules. It would be great if someone could share their experience on the best approach to build a stable and visually pleasing combination. What tips are there concerning fasteners, load-bearing capacity, and design options with different fronts? Thanks in advance!

You can easily combine the open modules with the closed ones. Important: when installing, be sure to use the mounting clips to keep everything stable. Doors can be simply attached to the carcasses, as the system fits together well.

The BESTA modules are designed so you can easily build different combinations. For open compartments, simply leave out the back panels and doors. Make sure the base units have the same depth to ensure a consistent appearance.

To be honest, I have concerns about stability when using mixed configurations. Especially when open and closed modules are stacked on top of each other and heavy objects are placed inside, this can be quite stressful. Are there reliable experiences indicating whether the original connecting elements are sufficient to handle this? Or would it be better to plan additional brackets or reinforcements? With other systems, this is often necessary.

The load-bearing capacity of BESTA depends on the chosen construction. Open units without a back panel have lower stability because they lack lateral bracing. For sturdy combinations, it is advisable to install and securely fix back panels at least on the closed units. Additional metal brackets or corner connectors are optional and may be recommended for taller or heavily loaded constructions, but usually the IKEA system connectors are sufficient.

Thanks for the responses so far. Regarding Victor54’s point: I mainly want to store light to medium-weight items in the open compartments, so stability seems less critical to me. However, I’m interested in the issue of connection tension and clean transitions between the modules. Is there a preferred order for assembly? How can you prevent the modules from shifting or wobbling? And what is the best way to combine this with doors without making the whole structure unstable?
