ᐅ How can I securely attach Ikea BESTA units to different types of walls?

Hello everyone, I recently purchased the IKEA Besta system and now want to securely mount it on different wall types. I plan to install the system both on a solid concrete wall and on a drywall (plasterboard) wall. It is important to me that the installation is really safe and strong, as I intend to store some heavy components inside. I am particularly interested in recommendations for suitable anchors, screws, and fastening techniques for each wall type. Are there any special considerations to keep in mind when working with the Besta system? Which screw lengths and types work best? I would also like to know if you use any additional reinforcements, such as brackets or anchor plates, to further increase stability. Thanks in advance for your experiences and advice!

Good decision to clearly distinguish between your wall types, as the mounting methods differ significantly. For concrete walls, I strongly recommend heavy-duty anchors, such as metal expansion anchors or high-quality plastic anchors with sufficient embedment depth—at least 50 mm (2 inches), depending on screw length. If the wall thickness allows, wedge anchors are an even better choice for maximum load capacity.

With drywall partitions, the situation is much more delicate. Standard anchors won’t suffice because the gypsum board alone cannot bear the weight. You should use special cavity anchors, like metal toggle bolts or spring toggle anchors, which expand behind the drywall and distribute the load. Depending on the load, it can also be helpful to reinforce the installation with a wooden batten or mounting strip behind the drywall.

Regarding the BESTA system itself: mounting usually involves the supplied hanging rails. Make sure to install these horizontally and on at least two fastening points per wall panel. Phillips screws are recommended, and for heavier loads, use thicker screws (at least 5x60 mm (5/16 x 2 3/8 inches) for concrete, 5x50 mm (5/16 x 2 inches) for drywall).

Additional support with brackets is always a good idea, especially if you expect heavier loads—they can be fitted inside at the corners. For shelves on drywall, you can also combine mechanical fasteners with load-distributing plates.

I’d be interested to know how you determined the wall thicknesses and the approximate weights you expect for the BESTA system. This would allow for more targeted advice!

I understand how important secure fastening is, especially with different wall types. It’s easy to underestimate how differently, for example, a concrete wall and a drywall (plasterboard) wall behave.

That really sums it up. In my case, I once used regular anchors, and the boards eventually gave way. The result: wobbly shelves and frustration.

Now I always take the time to use cavity anchors and add extra bracket supports for heavy items. That way, I feel much more secure.

You might want to find out approximately how heavy the individual items or cabinets will be in the end. Then we can provide more targeted advice on how strong the fastenings should be. I also find it helpful to always have a spirit level on hand to align the rails precisely – it saves trouble later on.

Here is a step-by-step guide for safely mounting IKEA BESTA units on concrete and drywall surfaces:

- First, clearly identify the wall type and measure the wall thickness.
- For concrete walls: drill holes using an appropriate drill bit (preferably a masonry bit), and insert suitable heavy-duty anchors (metal expansion anchors or sleeve anchors depending on the load).
- Screws should be long enough to fully engage the anchors—usually 6-8 cm (2.5-3 inches), depending on the thickness of the cabinet back panel plus anchor length.
- For drywall: use metal toggle bolts or spring toggle anchors. These spread out behind the drywall panel to better distribute the load.
- Recommendation: if possible, attach the units to the studs within the wall. If this is not possible, add additional reinforcements (e.g., wooden battens behind the drywall).
- Mount the BESTA fixing rails horizontally to ensure the load is evenly distributed.
- For heavy cabinets, always install additional brackets, which significantly increase stability.

When screwing, always follow the manufacturer’s specifications regarding weight limits and use the recommended mounting materials. Improperly mounted cabinets can cause serious accidents.

One more question: Are the concrete walls smooth or rough? This can affect the choice of drill bit.

I would like to point out that the discussion so far has been very practical, which is good. However, I often see that the attachment of Ikea furniture like BESTA to drywall (also called plasterboard or gypsum board) is rarely questioned critically.

Although this anchor technology is technically sound, it is often overlooked that the effective load capacity depends heavily on the quality and thickness of the drywall, the positioning of wallpaper or plaster layers, as well as the overall distribution of the load.

I would advise everyone never to mount the BESTA system solely at a single point on drywall without additional measures such as reinforcements with wooden battens or anchoring into statically load-bearing elements of the wall.

Furthermore, I recommend, if possible, to transfer the load to multiple fastening points or to the floor instead of relying solely on wall mounting. This is, in my opinion, essential for “heavy components” and is often underestimated.

How exactly do you plan the load distribution, LU_DO? What specifications are there regarding the total weight class of the planned BESTA installation?
