ᐅ What fastening options are suitable for additional inserts in IKEA Besta units?

Hello everyone, I want to add some extra inserts to my IKEA Besta shelving unit to create a more customized layout. My question is: What are the best fastening options to securely and permanently attach additional shelves or inserts within a Besta system? It’s important to me that the solution is stable, preferably reversible or can be done without causing significant damage to the furniture, and that it doesn’t affect the appearance. I’ve considered small screws, brackets, or special fittings, but I’m not sure what the best approach is. Are there any suitable IKEA accessories, DIY tips, or specific components you would recommend? Thanks in advance for your advice!

Hello, basically it is easiest if you use the designated pre-drilled holes in the Besta side panels. These holes are standardly positioned for dowels or shelf supports. If you want to install additional shelves or inserts, there are the following options:

- Use IKEA shelves with matching brackets that fit into the pre-drilled holes.
- For inserts that you want to fasten with screws, for example, you can use small angle brackets that can be attached to the back panel or the sides depending on the insert.
- Alternatively, there are rail systems that can be mounted on the sides to allow flexible insertion of inserts.

It is important to ensure that you do not compromise the rear stability, especially if the insert is meant to support weight. Screws in the side panels should be used sparingly to avoid damaging the material.

If you prefer a reversible system, clamp holders or magnetic fasteners are possible, although they may have limited load capacity.

Great question! I recently added some extra inserts to my Besta shelf as well – and I have to say, it’s really fun and adds a lot of flexibility! 🙂

I used self-adhesive metal brackets for this; they are easy to install and don’t damage the surface as much since you don’t have to drill large holes. Just stick them to the sides, let them dry briefly, and the insert holds firmly. For extra stability, I also used small screws that can be placed into the pre-drilled holes in the cabinet frame.

Another thing that works well: those small plastic clips that IKEA originally provides for shelves – they’re really practical for securing inserts without much effort. My advice: don’t hesitate, just give it a try, the Besta system is really versatile!

The topic of attaching additional inserts to IKEA Besta units is indeed interesting and frequently discussed. From a construction perspective, the Besta system offers several options:

- The pre-drilled holes in the side panels are well suited for traditional brackets and screws.
- For inserts that need to be removed flexibly, using connectors or clip holders that fit the standard holes is advisable.
- If the inserts are heavy, the load should be distributed over multiple points to avoid overstressing the material.

I also recommend considering the material of the inserts. Solid wood or MDF requires different fastening methods than plastic or metal parts. A combination of brackets and cushioned adhesive elements can provide a secure hold without damaging the furniture. Additionally, I suggest continuously checking the stability during assembly.

I used small brackets from the hardware store for my Besta inserts, which were simply fixed to the sides with short screws. They hold very well and are easy to remove. It is important to pre-drill the holes deep enough to prevent the material from splitting.

For additional supports, I recommend using screws together with angle brackets. Avoid adhesive, as it can fail over time. Pre-drill to prevent cracking.
