ᐅ How can I install IKEA Metod cabinets securely on uneven floors?

Hello everyone,

I am planning to install several IKEA Metod kitchen cabinets in my new apartment, but I have the problem that the floor is very uneven. The irregularities amount to up to 2 cm (0.8 inches) in some places. My goal is to assemble the cabinets as stable and secure as possible without them wobbling or being permanently damaged. The assembly instructions provide little information on how to best deal with an uneven floor.

I am mainly interested in practical methods to level and align the cabinets at floor level permanently. Are there materials that are well-suited for the base or special adjustable feet available from IKEA or that can be custom-made? Does anyone have tips on the correct procedure to minimize stress and the risk of tipping?

How can I build my Metod cabinets stably on an uneven floor? What steps should be followed, and which tools or aids are particularly helpful? I look forward to your experiences and recommendations, thank you!

The most important point is that you don’t simply place the cabinets on the uneven floor and immediately screw them together. The cabinets need to be individually adjustable; otherwise, the forces will be distributed unevenly, causing the material to warp or the joints to loosen.

IKEA provides height-adjustable feet that can be adapted to the module height. You should first attach these feet and then carefully level each cabinet individually.

My recommendation would be to also use a thin, durable leveling mat. Some people use thin silicone pads or self-adhesive felt pads as an intermediate layer—they provide cushioning and compensate for minor irregularities. If the unevenness is more significant, adding shims made from wood or metal strips under the feet often helps.

Ensuring a level, solid foundation is crucial with Metod cabinets because the cabinet base structure is quite delicate and cannot withstand strong deformation. I would definitely make sure to set the feet carefully and securely, rather than just using a few thick washers that might slip.

Remove the adjustable feet from IKEA furniture, check the floor level with a spirit level, and stabilize using wooden shims or metal washers. Secure everything firmly with screws.

To stabilize IKEA Metod cabinets on uneven floors, I recommend the following systematic approach:

- Measure the unevenness at specific points using a spirit level.
- Attach the adjustable feet provided by IKEA to each cabinet.
- For fine adjustments, use washers or specific plastic or wooden shims under the feet to compensate for height differences precisely.
- After each adjustment, check the level again with the spirit level.
- Screw all cabinets together to form a stable unit, which reduces wobbling.
- Optionally, a supplementary baseboard (e.g., MDF or HDF) can be placed on the floor as a foundation if the floor does not compensate for the unevenness sufficiently.

Important: Avoid using loose or unsecured leveling materials. These must be load-bearing and slip-resistant to ensure long-term stability.

Great question, I had the same issue myself! I simply used large wooden shims, placed them precisely under the feet, leveled everything with a spirit level, and then screwed the cabinets together. This provides really secure support and you barely notice that the floor is uneven.

One tip: If you’re lucky, the adjustable legs from IKEA are long enough to compensate for the unevenness; otherwise, an extra thick spacer will help. Good luck, it definitely works!

That’s a tricky issue. In my opinion, relying blindly on IKEA legs is often a flawed approach. In practice, they are not always sturdy enough and tend to give way under load, especially on actual floor unevenness over 1cm (0.4 inches).

Some overlook that an uneven floor is essentially a poor foundation, and using these legs is just a temporary fix.

Another option would be to create a solid leveling base—perhaps a sheet of water-resistant plywood or MDF—and then place the cabinets with legs on top of it.

This not only prevents wobbling but also avoids long-term deformation of the cabinets caused by lateral forces.

I doubt that simply adjusting “a few leveling feet” is the best solution in the long run, especially when several units are connected.
