Hello everyone,
I’ve recently noticed that the shelves of my BILLY bookcase bend and warp over time, even under normal load—and I haven’t overloaded them. The load corresponds quite closely to the manufacturer’s specifications, so no more than 30-40 kg (66-88 lbs) per shelf, mainly books and a few smaller decorative items. Still, the shelves show visible bending or slight warping at the edges.
My question is: why do BILLY shelves warp despite normal use? Is it due to the materials used, assembly errors, environmental factors, or is this simply a known issue with this piece of furniture? Are there any tips on how to prevent or fix this? Thanks in advance for your insights!

Hello Bulumar,
The warping of the BILLY shelves despite normal load can have several causes. Firstly, the material – particleboard with melamine coating – is naturally less stable than solid wood and prone to moisture absorption. Fluctuations in humidity and temperature can therefore cause swelling and deformation.
Another factor is the design: the shelves are relatively thin (about 1.8 cm (0.7 inches)) and are only supported at specific points on the sides. Under prolonged load, the material can bend, even if the weight does not seem particularly high.
Installation errors also play a role, for example if the shelves are not properly resting on support pads or the brackets are not securely fixed.
In summary: material properties, environmental factors, and load design contribute to the observed effects. I recommend keeping the humidity as constant as possible and using additional shelves or reinforcements for heavy loads.

Wieso verziehen sich die BILLY Regalböden trotz normaler Belastung? Liegt das an den verwendeten Materialien, Montagefehlern, Umwelteinflüssen oder ist das einfach ein bekanntes Problem bei diesem Möbelstück?

Oh yes, every Billy owner can probably relate 🙂
The shelves are definitely not heavy-duty solid wood, but more like a parachute made of particleboard. If you put a few too many heavy books on them, the board will even sag a little.
That’s exactly the main issue! On top of that, the slightly moist air when airing out the room gives the boards a mini sauna moment, and of course the material reacts with a tiny deformation.
I simply placed some sturdy supports under the shelves – voilà, the annoying sagging was gone. Sure, it’s not a high-end solution, but practical and inexpensive.
So: Billy is cool, affordable, and behaves like a sports car on cobblestones—not made for really heavy books 😉 🙂
