JuttakinHello everyone,
I plan to set up several IKEA Billy bookcases in my home office. The problem is that the floor there is not completely even – there are slight uneven spots, which makes the bookcase unstable. Are there any proven tips or specific methods to securely and permanently install a Billy bookcase on an uneven floor? I want to avoid the bookcase wobbling or leaning later on, and of course, it should also look reasonably neat. Technical solutions or installation tips that work well for minor floor irregularities would be ideal. Thanks in advance!

Hello Juttakin,
I would like to give you some tips on how to securely install your BILLY shelf unit on an uneven floor.
First of all: small unevenness of a few millimeters can usually be compensated well with adjustable furniture glides or shims. IKEA offers so-called "wooden feet" for BILLY, which can be unscrewed and replaced with adjustable feet.
Here is a simple step-by-step guide:
1. Measure the biggest differences in the floor level where the shelf will stand.
2. Assemble the shelf completely, but do not fix the back panel yet. This way, you can still make slight adjustments.
3. Under the regular shelf feet, you can place furniture glides with height adjustment or small rubber shims.
4. Set the shelf upright and check with a spirit level if it is standing straight.
5. If the shelf wobbles, you can fine-tune it with small wooden wedges or rubber buffers under the feet.
6. Once the shelf is properly aligned, you can attach the back panel and, if necessary, secure it with screws to prevent slipping.
Important: Make sure there are no large gaps between the shelf and the floor, as this can lead to tipping or objects falling underneath later on.
If the unevenness is too great, you could also use a thin OSB board or thin particleboard as a base, leveling it beforehand.
I hope this helps you move forward!

Hello Juttakin,
I want to break this down in more detail because success with uneven floors often depends on careful preparation.
This is a very good approach, which I would like to add to:
1. First, use a long straightedge and a spirit level to measure the floor unevenness precisely. Where are the height differences, and how large are they? Only then can you plan the compensation accurately.
2. If the unevenness is between approximately 3 and 10 mm (0.1 and 0.4 inches), so-called “height-adjustable furniture feet with threads” are suitable, which can be screwed directly under the shelf. This allows you to adjust each corner individually. IKEA actually sells these feet as an alternative for BILLY.
3. In your case, it might make sense to remove the original feet and replace them with such adjustable feet.
4. If the floor is even more uneven, over 10 mm (0.4 inches), you should consider whether a small leveling board is useful, for example, a thin 8–10 mm (0.3–0.4 inches) multiplex board, which you level with a spirit level beforehand. You could also have the board cut to size by a carpenter.
5. Then place this board as a base under the shelf. If you are handy, you can glue it directly to the floor without flooring covering or secure it with appropriate screws to keep it stable.
6. Always check the stability after positioning the shelf. A wobbly shelf is dangerous, especially if there are children or pets in the home.
By the way, I recommend using a spirit level during the entire assembly, especially with strong unevenness. Even small deviations in placement multiply with the shelf height.
One more tip: BILLY shelves are relatively light, so it is especially important to secure them to the wall. This greatly reduces the risk of tipping, especially on uneven floors.
How about your wall mounting? Do you have the option for that?
Best regards!

Jensson schrieb:– That is correct, because gaps promote tilting or slanting. The back panel of the BILLY shelf only helps if the base frame is stable.
Make sure not to leave large gaps between the shelf and the floor

Thank you for the detailed explanations, Jensson and TEBILO!
Regarding your question, TEBILO: Yes, the shelves will also be fixed to the wall. I was just concerned that wobbling caused by an uneven floor could still be an issue.
I estimate the unevenness to be around 5-7 mm (0.2 to 0.3 inches), so probably right within the range for those adjustable furniture feet.
I will check the measurements today using a straightedge and a spirit level. I’m just a bit worried that the adjustability of the feet on BILLY shelves might be quite limited.
Do you have any experience with how much height adjustment is possible, for example, with common furniture gliders? And is there a specific type of rubber or felt you would recommend for these situations?

To summarize: The combination of adjustable feet plus felt- or rubber-coated glides is one of the best solutions for minor floor unevenness when assembling shelves.
Adjustable furniture feet usually allow height adjustments between 10 and 15 mm (0.4 and 0.6 inches), which should be sufficient for your case (5–7 mm (0.2–0.3 inches) of unevenness). Additionally, felt glides not only protect the floor from scratches but also help absorb slight unevenness, significantly reducing wobbling.
It is important to regularly check felt glides and replace them when worn out—otherwise, they may lose effectiveness. Some models combine felt with a non-slip rubber coating.
Therefore, I recommend looking for so-called "adjustable furniture feet with felt or rubber caps" at quality furniture or DIY stores. The costs are moderate, and installation is simple, often involving just screwing or plugging them in.
If the shelf is attached to the wall, stability is further ensured, but floor clearance remains important for safety and appearance.
Good luck with the project!

Hello Juttakin,
to add to the discussion about installation on uneven floors, I would like to share some technical and procedural details that are often overlooked.
1. Selection of leveling materials:
There are different materials for leveling the floor:
- Wooden wedges: easy to cut but prone to pressure marks and moisture.
- Plastic wedges: more durable and weather-resistant.
- Rubber pads/inserts: flexible and non-slip.
2. Mounting the feet:
Especially for modular furniture like BILLY, it is advisable to remove the original feet and use special adjustable leveling feet with threads, which allow precise adjustment up to 15 mm (0.6 inches) or more.
3. Procedure:
- First, place the shelving unit approximately at the intended location.
- Use a long spirit level to determine the horizontal level and mark which feet need adjustment.
- Prepare and temporarily install the leveling screws or feet.
- Additional rubber buffers between the foot and the floor prevent scratching and provide slight cushioning.
4. Practical experience with significant unevenness:
For floors that are not only slightly sloped but also wavy, it is recommended to use a custom-made leveling board. This can be made yourself (plywood or oriented strand board - OSB) or have it cut to size.
Additionally:
Yes, that is very sensible. Felt pads prevent scratches and ensure the shelving unit does not wobble on hard spots. When combined with adjustable feet, this results in a very durable and stable setup.
Very important: Final fixation to the wall is mandatory for BILLY, not only for safety reasons but also because it prevents the unit from constantly shifting due to floor movements.
Maybe you can provide some details about the floor material and the exact unevenness? What type of material is it, and how pronounced are the wavy spots exactly?
