ᐅ Why does the Malm bed squeak when suddenly put under pressure?

I have been dealing with an issue for some time regarding the Malm bed from Ikea, specifically the unpleasant squeaking noise that occurs when I suddenly sit down or move quickly on it. I am especially interested in understanding why this squeaking happens. I suspect it may be related to the construction or materials used, perhaps wood and metal at certain contact points, but I am not sure. Are there mechanical reasons why this noise is triggered specifically by sudden pressure? Could it be related to friction, material fatigue, or loosening of screws? Has anyone had experience with the Malm bed and can explain this in more detail? Thanks in advance for your feedback!

It’s great that you brought up this topic! 🙂 I experienced the same issue and found it really annoying. Most of the time, the squeaking occurs because wood and metal move against each other, creating small friction noises. Especially under sudden stress, the force can be strong enough to slightly shift the joints, even if it’s barely visible.

Often, screws are a bit loose, and when nothing is tightly fastened, the squeaking can be quite loud. So definitely check and tighten all the screws! Also, if dust or small particles collect between the parts, applying a bit of lubricant can help eliminate the noise. It’s really helpful once you understand this! ;-)

A common cause is moving parts and loose screws.

Exactly, check the screws, especially at the connections between the headboard, footboard, and the frame. Then you can lightly sand the wooden slats and apply some wax or lubricant to the friction surfaces.

The cause of the squeaking noise when the Malm bed is suddenly loaded can be technically explained by the interaction between material properties and mechanical joints.

The Malm bed is mainly made of particleboard with a decorative laminate and is held together by screws and metal brackets.

Sudden loading creates shear and tensile forces, which can cause the fasteners to move slightly. This micro-movement at the interface between two materials—especially wood and metal parts—generates frictional forces. The smooth or slightly rough contact surfaces can produce vibrations that are perceived as squeaking.

Additionally, dust particles or small changes in humidity can affect the friction behavior. Precise fastening and occasionally retightening the screws significantly reduce these movements and thus the squeaking.

Check all connections and tighten any loose screws. Are wood and metal rubbing against each other? Then apply lubricant to the contact points. The problem will be resolved.

An important but often underestimated cause is material deformation under load.

Particle boards can warp slightly under load, which leads to a minor displacement of the screw connections. This slight give then creates the friction and the squeaking.

In addition to tightening the screws again, I recommend not to overtighten them to avoid damaging the material. Rubber buffers or felt pads at the contact points can also help reduce the noise.
