Hello everyone,
I have a question that has been on my mind for a while, and I hope to gain some insights here in the forum: Why do some IKEA Billy bookcases change color over time? Specifically, I have noticed that some models I use show fading or yellowing in places after several years, while others in similar environments remain almost unchanged.
I suspect that various factors such as UV exposure, humidity, or the surface coating might play a role, but I would like to understand exactly what causes this color change, whether it is a normal aging process of the materials, and if there are any ways to prevent it. Perhaps others here have experience or background knowledge about the materials and surface finishes used on Billy bookcases?
I look forward to an interesting discussion and many helpful answers!

I’m taking a closer, more technical look at the topic:
Billy-style shelves are usually a multi-layer construction consisting of a particleboard core and a decorative surface, often a melamine or foil coating, as GiRoyce has already mentioned.
Regarding color changes, two main processes are involved:
1. Photooxidation: UV rays produce free radicals on the surface that break chemical bonds and can alter pigments. This appears as yellowing, fading, or color shifts.
2. Thermal-mechanical effects: Temperature fluctuations and humidity cause stresses in the coating and core material. This leads to small cracks that reduce the protective effect and accelerate oxidation.
My advice: If possible, place the shelf where it is not constantly exposed to direct sunlight, which greatly helps maintain color consistency. In rooms with consistently high humidity, some slight changes should still be expected.
On the subject of repair: there are specialized furniture care products with lightly pigmented wax or UV protective films that can slow further darkening or fading. However, true restoration of the original color is nearly impossible with the thin melamine coating.

Hello everyone! :-)
It’s really interesting how much there is to consider here. I think it’s important not to forget that shelves like the Billy are actually lifestyle products that are constantly being developed further. IKEA, of course, also focuses on cost efficiency to offer affordable prices.
Let’s be honest, a piece of furniture like this isn’t meant to be a museum exhibit. Especially when you think about the effects of sunlight and so on – I almost see it as a kind of patina that gives the furniture character, even though it’s really just chemical processes.
If that bothers you or you don’t want it, simply try moving the furniture around every now and then or closing curtains.
And if the finish really suffers visibly, maybe you can add a bit of creativity by building, painting, or using adhesive films yourself. 😉
Alright, enough chatting. Thanks for sharing your thoughts!

Brief and to the point:
UV radiation and heat cause the surface to fade.
Moisture can deform the material.
Protection through shading, distance from heaters, and maintenance with wax.
For long-lasting color, inexpensive furniture is often not sufficient for strong sun exposure.
