ᐅ How can I most securely attach IKEA Besta units to properly constructed walls?

Hello everyone, I am planning to mount several IKEA Besta cabinets securely to properly constructed interior walls to ensure a stable and safe wall installation. The walls consist of plastered masonry with hollow-core concrete ceilings above. My specific question is: What methods and fasteners are best suited to securely fix the Besta units so that nothing loosens or shifts over time, even with prolonged use, such as loaded shelves or hanging objects? Which anchors, screws, or brackets are most reliable for this, and are there any particular considerations regarding the weight and material properties of the walls? Any tips on anchoring and possible additional reinforcements are greatly appreciated.

I completely understand this concern, as anyone who wants to firmly mount something on a wall probably does. What helped me was using the right anchors for the type of wall – ideally high-quality nail anchors or heavy-duty anchors that are deeply embedded in the wall. I was worried the screws might loosen after a few weeks, but with enough pre-tension and properly set anchors, everything stays rock solid.

I also recommend aligning the cabinets flush with the wall and securing them at multiple points, not just at the top. Especially if you intend to store heavier items, distributing the load across several fixing points makes a big difference. It’s also important to use screws of the correct length so they’re not just holding in the surface plaster but are anchored deeply into solid masonry.

I know this isn’t a perfect scientific answer, but perhaps it’s helpful to hear from real experience that has proven reliable with standard walls.

For a factual answer: For plastered masonry without cavities, heavy-duty anchors with the appropriate screw are the best choice. Important points:
- Pre-drill according to the size of the anchor
- Consider load distribution by using multiple fixing points
- For load-bearing walls, chemical anchors provide systematically secure fastening

For hollow-core or concrete ceilings, it is advisable to use special hollow wall anchors or screws with expansion mechanisms if mounting from above.
Also recommended: Connect the IKEA Besta units together, as this often creates a stable assembly that can better distribute additional loads.

For maximum safety, I would exclusively use the original screws with the correct diameter and length as recommended in the IKEA instructions, combined with the anchors mentioned. This helps avoid damage to both the furniture and the wall.

That is a very good point. In addition, I would like to emphasize that securely mounting the Besta units on the wall always requires fastening materials that are specifically suited to the wall type. For masonry made of bricks or concrete, strong anchoring with chemical anchors or heavy-duty anchors is advisable, as they can permanently withstand high tensile and shear forces.

Furthermore, the placement of the fasteners is important: they should be located in solid wall areas and not in grooves or mortar joints. Before installation, it is advisable to use a suitable detector to rule out metal or voids.

The screw length should slightly exceed the anchor length to fully utilize the holding power without damaging the wall. For especially heavy loads, such as filled cabinets, adding extra braces or a sturdy mounting rail behind the Besta units can be an effective way to transfer pressure forces away from the wall.

A professionally constructed wall is the most important factor here – if there are any damages or unstable plaster, I recommend an inspection before mounting.
