ᐅ After installing new baseboards, the compartments of my Kallax shelving unit no longer sit flush – any solutions?

Hello everyone,

I recently installed new baseboards along the walls in my apartment. Since the installation, I’ve noticed that the compartments of my Kallax shelving unit now stand noticeably above the floor compared to before, meaning they no longer sit flush. I placed the shelf in the same spot as before, but the new baseboards seem to be slightly thicker than the previous ones, causing the Kallax compartments not to rest evenly on the floor.

This results in some doors not closing properly and the furniture feeling generally unstable. Since I want to avoid scratching the floor or damaging the shelf, I’m looking for a suitable solution to fix this issue in a clean and lasting way.

Has anyone experienced Kallax compartments “standing off” due to newly installed baseboards? Are there practical tips for adjusting the shelf to the changed floor conditions? For example, using appropriate shims, special leveling feet, or other modifications?

Thanks for any helpful advice or shared experiences!

I am well familiar with this issue. New baseboards often change the floor height or the gap to the wall edge, causing furniture to no longer sit flush.

My recommendation: First, check if the floor under the Kallax is still level—changes from installing the baseboards or added cable conduits can create slight unevenness.

A common solution is to attach adjustable furniture glides or leveling feet under the Kallax shelves. These can be adjusted to compensate for small height differences and unevenness without causing the unit to wobble or doors to stick.

If the shelf is not designed for this, small wooden strips or felt pads can be placed underneath. These provide a shock-absorbing, gentle adjustment that can be easily removed later.

Important: Avoid permanent adhesives that might cause problems when moving later.

I hope this helps you.

Recommended are interchangeable furniture glides or height-adjustable leveling feet.

Additionally, here is a brief guide on how to approach the problem systematically:

1. Measure: Measure the height of the new baseboards and compare it to the height of the original floor before the baseboards were installed. This way, you will know exactly how much height difference you need to compensate for.

2. Choose the underlay: There are various options – felt pads, thin wooden strips, plastic shims, or height-adjustable furniture feet. Felt pads protect the floor but are not always stable enough for larger height differences.

3. Check installation: Some Kallax versions allow you to place simple furniture feet or custom-cut strips underneath. Alternatively, you can position small shims precisely, for example at the corners.

4. Stability check: After leveling, test if the shelf now stands steady and without wobbling. If necessary, tighten screws or add support material in specific spots.

5. Test doors: Make sure the doors close smoothly again. A warped piece of furniture can cause permanent damage to the hinges.

Common mistakes include not compensating for unevenness and using materials that are too soft and compress quickly. Don’t get discouraged; often it takes some trial and error.

For very uneven floors, a leveling substructure, such as a thin board cut to size, can also help.

Place furniture glides or wedges underneath.

In short: Use plastic or felt furniture glides and place them at specific points under the shelf. This will raise it to the height of the support strips and prevent wobbling.

Alternatively, get adjustable leveling feet that can be screwed on.
