Hello everyone,
I have a Kallax shelving unit from Ikea and have noticed that the middle shelf bends downwards under load over time. My question is: why does the shelf in the Kallax unit sag downwards, even though the unit is supposedly designed to hold books or other items without sagging? Are there common causes such as material properties, load limits, or construction details that one should be aware of? And how much sagging is considered normal before it can be regarded as a defect? I look forward to knowledgeable explanations and advice on how to prevent this.
