ᐅ KALLAX as a compact kitchen – countertop does not stay firmly in place

Hello everyone,
I am currently building a small kitchenette using a KALLAX shelf unit from Ikea to accommodate a mini kitchen. I placed a wooden countertop on top to serve as a cooking and preparation surface. Unfortunately, I noticed that the countertop does not sit firmly on the KALLAX and tends to shift quite easily, especially when I work on it or apply light pressure.

My question is: What options are available to secure the countertop to the KALLAX in a way that is stable and safe without damaging the shelf unit? Are there any tried-and-tested tricks or materials that can reliably fix the countertop in place? I am also interested in whether this construction is generally suitable for a mini kitchen, which needs to withstand some level of load.

I look forward to your tips and experiences!

Before we discuss solutions: The stability of a countertop greatly depends on the type of fastening and the materials used. Have you checked how the wood might warp or if moisture could affect adhesion?

Without proper fixing, slipping is almost inevitable. A common idea is to screw the countertop into the edges of the KALLAX, but of course, this will damage the furniture. Alternatively, clamp profiles or non-slip adhesive materials are recommended.

Using tape underneath can help temporarily, but it is more of a makeshift solution. What type of wood board have you chosen exactly? Tip: knowing this helps to recommend the best method precisely.

You can place foam rubber pads or anti-slip mats underneath; this effectively prevents slipping.

If screws are not an option, then clamp strips are a good choice.

Hello nika54,

I understand the issue with slipping when using KALLAX as a mini kitchen. Especially if the countertop is just placed loosely on top, movement can often be noticeable. What you can try is applying so-called "anti-slip pads" at the contact points between the shelf and the countertop (these are available at hardware stores or online). They are thin, very adhesive, and also protect the shelf from scratches.

If you want a slightly more professional solution, you can use angle brackets. Screw them from the inside of the KALLAX unit so that they clamp the countertop firmly but minimally, without affecting the appearance on top. This makes the countertop much more stable without causing any damage on the outside.

Another tip: make sure the countertop itself is stiff enough – wood or MDF that is too thin can bend and reduce the strength of the support.

If you like, I can gladly provide you with a step-by-step guide.

A common idea is to screw through the board into the edges of the KALLAX, but this will obviously damage the furniture.

The Kallax is mostly made of particleboard with a thin melamine coating. Direct screwing is possible but requires pre-drilling and can reduce stability if disassembled frequently.

Therefore, clamp brackets or special clamping devices that grip under the board and into the shelves are recommended. This method provides high stability without visible changes to the furniture.

In addition, a heavier board is better for stabilization: an 18 mm (0.7 inch) thick solid wood board is more suitable than thin particleboard or MDF panels.

In summary:
- Pre-drill when using screws
- Prefer clamp brackets
- Choose a worktop that is as thick and sturdy as possible
- Use anti-slip mats on smooth surfaces

These parts are available from specialist retailers and can be installed with basic tools.

I put together a KALLAX setup for my small kitchen project. A little tip: if you apply self-adhesive anti-slip pads (the kind used for carpets) to the underside of the countertop, it holds really well and leaves no marks.

If you’re a bit handy, you can use small angle brackets – they will be visible underneath but hold the countertop very securely. And don’t worry, the KALLAX handles it well.

One side note: make sure the countertop sits completely flat. No matter how good the mounting is, it won’t be stable if it wobbles anywhere.

Good luck with your project! 🙂
