anberkay681 Apr 2019 08:17Hello everyone,
I have been experiencing an issue for some time where the screws on my Ikea Malm bed have loosened multiple times, even though I have not moved or rearranged the bed. I am curious: why do screws tend to loosen on Malm beds? Are there possibly design weaknesses, materials, or dynamic stresses that cause the fastenings to loosen over time? I have already tightened the screws several times, but that usually only helps temporarily.
Perhaps someone here has experience or explanations about the cause and how to effectively prevent this without constantly needing to retighten. From a technical perspective, why don’t the connections remain securely fastened permanently?
Thanks in advance for your insights!

Hello anberkay68,
regarding your question about why screws tend to loosen on Malm beds, I would like to offer some technical insight. Basically, these beds are made primarily of particleboard with a thin veneer layer. The screws therefore connect engineered wood panels rather than solid wood, which often affects the durability and stability of the joint.
The main issue is that the material slightly yields or deforms under stress—such as movements during sleeping or getting in and out of bed. This can cause the threads in the particleboard to loosen since the material is not designed to hold screws under repeated load and permanent tension.
Additionally, it should be noted that many of these screw connections are complemented by cam locks or dowels. While this helps in the short term, it often is not sufficient to ensure a lasting tight hold over time.
This is exactly the core issue. The stress distribution in the joints is not always ideal, especially with particleboard, which can swell and shrink due to humidity. To improve this, it is often recommended to use metal threaded inserts in addition to the original screws or at least screws with special locking features.
One more thing: Have you checked whether the screws themselves might loosen easily due to material fatigue or poor quality? Sometimes, low-quality screws simply do not hold well.
What type of screws are you using, and what exactly does your bed look like (panel material of the side parts)? That could help narrow down the cause more precisely.

Hello anberkay68,
I would like to approach this topic from a slightly different perspective and explain the fundamental physical causes. Screws usually loosen due to so-called micro-movements and vibrations, which can occur even from small movements in the furniture.
That’s exactly the point. Every time you move in bed, these small shifts and shear forces are transferred to the screw connection. As a result, the nuts or screw heads can slowly and steadily loosen over time.
Another factor is the material, as already mentioned: particleboard has a certain elasticity and deforms – especially over a longer period and with changing humidity. It is not as dimensionally stable as solid wood.
Therefore, screws fixed in this type of wood cannot “simply hold forever” because the holding power is limited by the material. Often, it helps to secure the screws with threadlocker (such as Loctite or similar) to prevent loosening from the first movements.
My advice: regularly check the screws and, if necessary, gently retighten them with a torque wrench (not too tight to avoid damaging the material), and if possible, use locking washers or threadlocker for a lasting hold.
Did you perhaps tighten too loosely or too tightly during assembly? That also affects the stability of the screw connections.

In summary:
The reason screws loosen in Malm beds is mainly due to the combination of the material (particleboard) and the mechanical stresses the joints are subjected to. Particleboard is prone to deformation under pressure and moisture, which explains the loss of connection strength.
There are no serious design flaws as such; rather, this is a typical characteristic of furniture made from particleboard panels connected with screws and dowels.
To minimize the problem, the following actions can be considered:
1. Use of thread-locking fluid or similar products to prevent loosening.
2. Use of longer or thicker screws that grip deeper and more securely in the material.
3. Installation of threaded inserts (metal inserts) in the panels to improve joint security.
I emphasize this because excessive torque can damage the particleboard, which only worsens the problem.
However, a permanent solution is never fully guaranteed with this type of furniture, as it was not originally designed for constant wear or high dynamic loads.
