ᐅ My Kallax unit will be placed on a concrete floor – any recommendations for securing it?

Hello everyone, I just bought a Kallax shelf and want to place it in my home office on an untreated concrete floor. To prevent the shelf from shifting or becoming unstable under load, I’m looking for recommendations on how to securely fasten or fix it to this type of surface. It’s important to me that the fastening can be removed later without leaving significant marks, in case I want to move or remove the shelf at some point. Does anyone have experience with specific anchors, adhesive methods, or other solutions that work particularly well on concrete? Tips on suitable floor protectors or rubber pads that prevent slipping would also be appreciated. Thanks in advance for your advice!

The best approach is to drill holes into the concrete and use heavy-duty anchors. This is secure and holds well under load. If residue-free removal is important, you can also use anti-slip pads underneath.

For mounting on concrete floors, chemical anchors with epoxy resin are recommended to achieve a very durable fixation that can potentially be removed without residues. Heavy-duty anchors offer strong mechanical load capacity but usually leave visible drill holes when removed. Alternatively, special rubber or silicone pads with high friction can be used to prevent slipping without the need for drilling. These are often available in furniture stores and also protect the floor. It is important to consider the load on the shelving – for light use without heavy weights, a combination of anti-slip pads and adhesive tape may be sufficient.

That might be mechanically stable, but isn’t that overkill for a Kallax? Sometimes I feel like all household furniture is treated like a demolition job. Why not just use fixed rubber or felt pads to prevent scratches and provide enough grip? Sometimes it seems like people try harder to integrate the concrete into the furniture rather than the other way around ;-) Also, don’t you think that residue-free removal is often a myth with these types of fixings?

The discussion here clearly shows how different the requirements for securing furniture can be. As someone who recently faced a similar issue, I can confirm that I was initially reluctant to drill heavily, mainly due to the often irreparable damage it can cause to the floor. In the end, I chose thick non-slip furniture pads, which stabilize the shelf well on concrete without using adhesive or anchors. However, I also understand those who want extra security for heavily loaded shelves. Perhaps a compromise: non-slip pads combined with hidden wall fastenings?

Absolutely! Anyone looking for a residue-free way to fasten something to concrete should be honest: every mechanical method means some form of intervention. I recommend not nailing furniture to the floor or walls, but rather equipping it with proper weight and rubber pads, and that’s it. Protecting the concrete also protects your own freedom to use the room more flexibly. And no, this is not laziness but foresight.
