ᐅ How can I secure BILLY shelves on uneven floors?

Hello everyone, I have a problem with my BILLY shelves from IKEA: the floor in my apartment is quite uneven, and I’m concerned that the shelves might wobble or, in the worst case, tip over because of this. My question is: what is the best way to secure BILLY shelves on uneven floors to ensure they stand stable? Are there specific tools or methods to compensate for unevenness and safely fix the shelves in place? I have already thought about using small wedges or special spacers but am unsure which solutions are truly reliable and safe in the long term. Thanks in advance for your advice!

To secure BILLY shelves on uneven floors, I recommend first carefully measuring and assessing the unevenness. Small gaps or height differences can often be compensated with self-adhesive felt pads or furniture wedges made of plastic or wood. It is important that the wedges fit firmly and that the load of the shelves is evenly distributed. Furthermore, the shelf should always be anchored to the wall, as this provides the main protection against tipping. The included wall anchors from IKEA are suitable for standard walls; for special wall types, appropriate anchors are recommended, such as those for concrete or drywall. Another option is to use adjustable feet or furniture feet with screws to individually adjust the height. However, this is not originally intended for BILLY and may require some DIY skills.

Hello Lili67, I have put together a brief guide that might help you:

1. Check the floor:
- Use a spirit level to determine how much the floor slopes or sinks where the shelf will be placed.

2. Level out unevenness:
- For deviations up to about 5 mm (0.2 inches): use furniture wedges or felt pads placed under the shelf feet.
- For larger unevenness: adjustable furniture feet can be purchased separately and fitted as needed.

3. Secure the shelf:
- Wall fixing is mandatory — BILLY shelves are not stable without wall anchors.
- Use appropriate wall plugs for your wall type (e.g., expansion anchors for concrete or cavity anchors for drywall).

4. Inspection:
- After leveling and securing, gently pull the shelf to check stability.

Note: Do not overload uneven spots to avoid placing excessive weight on individual contact points.

Exactly right; tightly fitting wedges prevent shifting and reduce the risk of tipping.

I can only agree with the previous answer. Additionally, I would like to point out that it often helps to stick small, self-adhesive rubber pads under the back feet or support points of a BILLY shelf. These prevent slipping and protect the floor. If you don’t have adjustable feet and the floor is very uneven, you may need to use several wedges in combination to level the shelf.

If you cannot install the wall bracket (e.g., in a rental apartment with restrictions), an alternative is to load the shelf heavily at the bottom to reduce the risk of tipping.

However, I personally always recommend wall mounting and creating a stable base by carefully leveling the support points on the floor. This will help avoid long-term damage to both the shelf and the wall.

Do not set the shelf load too high at uneven points to avoid overloading individual support spots.

I have a critical addition: Isn’t it actually negligent to just experiment with wedges on uneven floors instead of addressing the root of the problem? For example, one could have the parquet or floor itself leveled before placing furniture on it. So why secure BILLY shelves only with temporary aids?

Furthermore, BILLY shelves are very lightweight in construction – so instead of relying solely on wall mounting, it might be worth considering a stable furniture system or even alternative types of furniture if the floor is less than ideal. At least I wonder if that would be more sustainable than constantly wedging under the feet.
