Hello everyone,
I have noticed that some Billy bookshelves from IKEA only squeak when they are loaded—whether with books or other items. Without any load, you usually don’t hear any noise.
I am wondering what exactly causes this. Are there mechanical reasons, such as friction between the individual components or material stresses that only become noticeable under load? How does this relate to the design and the materials used?
I am also interested in whether the squeaking can be permanently eliminated through specific measures without disassembling or altering the shelf. Are there known problem areas, for example at the joints, or do uneven floors or load distribution play a role?
I would appreciate well-founded explanations or personal experiences on this topic!

A very interesting phenomenon you mention. The squeaking under load in Billy-style shelves can be well explained using a physical and mechanical approach:
When the shelf is viewed without any load, the wood or particleboard panels are in contact but not necessarily under stress. When books or other loads are placed on it, slight shifts and deformations occur due to the weight, generating compressive and shear forces at the joints.
These forces cause surfaces – for example, the particleboard panels – to move against or rub against each other. The squeaking results from friction at small irregularities and microstructures on the surface – the so-called “stick-slip” phenomenon.
The fasteners, such as dowels, screws, or cam locks, also play a role: if these are not completely tight, they can allow slight movements under load, causing noise.
The material itself should not be overlooked: particleboard and wood-based materials are hygroscopic, meaning they respond to moisture in the air. This can cause the material to swell or contract, which in turn changes how the parts contact each other and generates noise.
I would also be interested to know what exactly triggers the load on your shelf: is it mainly heavy books or more localized loads? Have you ever tried lubricants or Teflon pads at the joints? Such measures could help reduce the squeaking.

I can definitely understand why that annoys you – that quiet but irritating squeaking under load has caught my attention too. 🙂
It makes you feel a bit unsure whether the shelf is stable enough or if something might break. What helped me was regularly checking the screws and, if necessary, rearranging the shelf slightly to achieve an optimal weight distribution.
It’s also a sign that something is under stress. Maybe the shelf even has its own little "voice" 😄. But seriously, it helps me not to overthink it too much and just pay attention to how the shelf behaves.
Has anyone here ever consciously “listened” to these noises and figured out if certain objects make them louder or quieter?

I believe the statement “Squeaking usually comes from loose screws or dowels” should be more nuanced.
That is certainly one factor, but the complexity of material and component interaction is often underestimated.
I wonder: Isn’t the problem more related to the connection between the panels themselves rather than the connection to the screws? Because an overly tight screw can even create stresses in the wood under pressure, which may worsen the phenomenon.
Also: What is the condition of the base? An uneven floor can cause wobbling, which amplifies micro-movements in the shelving when loaded.
I am also interested if anyone has already checked whether different moisture levels in the wood and air significantly affect the noises or if the problem is purely mechanical.

1. Creaking is caused by micro-movements between components, especially at connection points such as screws, dowels, and edges.
2. These movements only occur under load because the pressure slightly deforms or shifts the boards.
3. The material used (chipboard) has a rough surface with small irregularities that create friction, particularly with changing humidity levels.
4. Unevenness in the floor can cause the shelving unit to tilt, leading to additional movement.
Practical measures:
- Regularly check screws and connections and tighten if necessary.
- Lightly lubricate contact surfaces (only in accessible areas!) or use felt pads.
- Ensure the shelving unit stands firmly on a level surface.
These recommendations have been objectively tested and are endorsed by manufacturers and furniture professionals.
