Hello everyone,
A few months ago, I bought and assembled a Billy bookcase from IKEA. At first, everything was fine, but over time the bookcase has warped noticeably, so the shelves no longer sit at right angles and the whole structure feels unstable.
My question is: Why does my BILLY bookcase warp after some time?
The bookcase is placed against an exterior wall, not directly by a window, but in a room with somewhat fluctuating humidity. All the shelves were installed according to the instructions, and I haven’t placed any heavy or unevenly distributed loads on it.
Could this be related to the material, or is it more likely caused by environmental factors? Are there ways to prevent the warping or to fix it afterward?
I look forward to your insights and advice!

Good morning,
here is a summary of what I have taken from your answers:
- Warping is mostly caused by changes in moisture, especially with particle boards.
- Location and humidity levels play an important role.
- Adding reinforcements later with sturdy metal angle brackets from a hardware store is a sensible idea.
- Screws for particle board should be as thin and short as possible; pre-drilling is recommended.
- Replacing the back panel with a plywood board is a good but more labor-intensive solution.
I plan to reinforce my shelf with a few angle brackets and then test how stable it is. In the worst case, I will consider the back panel option.
Thank you all for the helpful and detailed explanations! 🙂
