Hello everyone,

I currently have a BILLY bookshelf from IKEA that I want to place on a rather uneven wooden floor. The issue is that the floor not only has small irregularities but also noticeably slopes in some areas. I want to avoid the bookshelf tipping over, shifting sideways, or getting damaged over time due to the load.

My question is: How can I best secure or stabilize the BILLY bookshelf when the floor is uneven? What methods or materials are most suitable to ensure a safe and stable installation without affecting the bookshelf’s appearance or functionality?

I appreciate any tips and experiences, preferably practical suggestions on how to deal with this common issue when setting up furniture on uneven surfaces.

One important aspect to consider is the floor’s tendency to deform over time, especially with hardwood parquet or plank flooring. Unevenness can worsen due to movement, so a rigid wall mounting combined with flexible leveling elements at the base is advisable.

I recommend the following combination:

- Adjustable furniture feet, which you can pair with rubber washers.
- Then firmly secure the shelf to the wall using high-quality metal brackets and appropriate wall anchors.
- Also, regularly check the shelf’s stability and tighten any screwed connections if possible.

From my experience, a one-time installation is often not enough; it’s worth inspecting and readjusting after some time.

I also noticed that this point hasn’t been discussed enough:

First try the shelf without attaching it to the wall and slowly adjust each foot until it stands steady.

Sometimes the wall attachment actually hinders fine-tuning, because you need the shelf in its final position to adjust the feet perfectly.

From my own experience, I would recommend setting the shelf up loosely in its working position at first for adjusting the feet, possibly using small aids (paper, wooden strips) to adapt the height. Only when everything fits should you secure it to the wall.

This is a tip in case your shelf wobbles or tilts after the first attachment. Try to proceed step by step.

Initially position the frame for adjusting the feet loosely during installation, possibly using small auxiliary materials (paper, wooden strips) to adapt the height. Only once everything fits correctly should the wall mounting be installed.

That is exactly my experience as well! Just take a bit more time for precise measuring and proceed systematically.

Additionally, I want to offer one last tip:

Avoid using overly thick materials under the feet.

Why? Because in that case, the bearing at the furniture foot is no longer properly stabilized and may shift over time. Thin, dense plates or special rubber shims that don’t compress are better.

If you pay attention to these small details, you will have a much more durable and secure solution.

It is also important to pay attention to the load-bearing capacity of the materials used. Some cheap rubber wedges deform noticeably under higher pressure, which can lead to instability.

Another practical tip:

When using wedges or shims, the feet should always rest firmly without any room for movement. A small amount of mounting adhesive on the underside can help if a permanent solution is desired.

In general: combining several small measures will achieve the best result 🙂

Thank you all for your numerous and detailed responses!

I will definitely try the idea of adjusting the shelf first without fixing it in place and then attaching it afterward.

The topic of material choice for wedges and adjustable furniture legs is also clearer to me now – I will check out the hardware store for sturdy, suitable accessories.

The emphasis on using the right wall plugs for mounting was helpful as well, since I have a drywall and not every type of wall plug works there.

I’ll be happy to share an update after setting it up. If there are any questions I haven’t thought of yet, feel free to ask!
