Why can the back panels of Ikea Billy bookcases sometimes slide out so easily?
I have noticed that the thin fiberboard back panel of my Billy bookcase does not seem to hold firmly and can be easily shifted or even removed when lifting or moving the unit slightly. I would like to understand whether this is a design feature, a manufacturing compromise, or possibly a structural issue.
Are there technical limitations in how the back panels are fixed that reduce their securing effect? And how likely is it that an incorrectly installed back panel causes it to slide out more easily?
I’m interested in this topic because I’m worried that during a move such a back panel might come completely loose and make the bookcase unstable. Does anyone have experience with this or even a technically precise explanation?

The primary stability of the shelving unit comes from the side panels and shelves, not the back panel.

Back panels slipping out easily is often due to the groove on the sides being too wide or worn.That is correct; both manufacturing tolerances and long-term wear can reduce the fit of the back panel. Therefore, some users recommend securing the back panel additionally—for example, with small nails, screws, or clip fasteners.
