ᐅ Why does the MALM bed occasionally squeak under load?

I have a MALM bed from IKEA that occasionally creaks under load, especially when moving or sitting on it. The question I have is: why does the MALM bed only creak sporadically and not continuously? I suspect it might be due to material stresses, the construction, or specific contact points. Are there any known weak spots or maintenance recommendations to prevent the creaking? I would like to understand the causes in as much detail as possible in order to address the issue effectively without having to completely disassemble the bed.

The squeaking usually comes from friction between the wooden parts or screws that have loosened over time. Check the screws and tighten them, as this often helps.

A MALM bed is made from several glued and screwed wooden panels. The occasional creaking typically results from slight movements at the joints, especially when screws loosen over time with use. Wood-on-wood contact can also cause noises that are intensified by changes in humidity. This means that even minor fluctuations in indoor moisture can cause the wood to swell or shrink, leading to occasional rubbing sounds.

Hello Barja, the occasional squeaking often results from a combination of mechanical stress and material properties. If screws are slightly loose, parts can shift slightly under load, causing the noise. Additionally, movements can cause localized metal or wood friction at connection points, which does not occur constantly because the pressure varies depending on the angle of load. Regularly checking the fastenings and lightly lubricating the contact surfaces can usually resolve the issue.

The squeaking noise in the MALM bed under occasional load is often caused by mechanical processes. The design, which uses laminated particleboard and screw connections, creates multiple contact points with different material pairings (wood-to-wood, wood-to-metal). During use, varying forces act from vertical to lateral directions, leading to microscopic shifts, especially if screws were not tightened to the specified torque.

Another factor is humidity: wood reacts strongly to changes in moisture, which slightly alters its dimensions and causes assembly stresses. The combination of varying load, temperature, and humidity results in irregular squeaking rather than a constant noise, depending on environmental conditions and the type of use.

I would recommend:
1. Retighten screws according to the instructions with the correct torque.
2. Alternatively, use screws with washers to increase the bearing surface.
3. Lightly treat all wood surfaces that rub against each other with paraffin wax or silicone spray.
4. Monitor ambient humidity and use a humidifier or dehumidifier if necessary.

If needed, minimally replacing damaged fittings can also help. If there is a manufacturing defect in certain areas, a warranty claim may be possible.

Thanks for the advice. Does anyone know if the lubrication should be applied mainly to metal or wood surfaces? Are there any materials that should definitely be avoided because they could damage or cause the wood to swell? I want to avoid damaging the bed by using the wrong treatment.
