Hello everyone, I have an issue with my Billy bookcases from IKEA. I’ve noticed that the shelves tend to sag quite a bit under load. This is especially noticeable with shelves holding books or other heavy items. I’ve already tried installing the shelves correctly and distributing the weight evenly, but the problem persists. My question is: what can be done to prevent or at least minimize this sagging under load? Are there reinforcing measures, replacement parts, or a specific setup that can make the shelving unit more stable? I’m looking forward to advice, preferably with explanations on how to adjust the shelves accordingly.
Good question, Taklo56! Sagging shelves in BILLY bookcases is a common issue. Here are some points that might help:
1. Material and thickness of the shelves: By default, the shelves are made of particleboard with a thin melamine coating. This is not very strong under heavy load.
2. Add reinforcement: For example, you can screw wooden strips to the front and back edges underneath the shelves or use metal angle brackets.
3. Additional center support: The easiest way to increase load capacity is to install a vertical support in the middle of the shelf.
4. Avoid heavy loads on upper shelves: Place heavy items on the bottom shelves, where less bending occurs.
5. Replacement shelves: IKEA sometimes offers thicker shelves, for example in the VARIERA series, which are more durable.
In summary, reinforcement and adjusting the load distribution can make a big difference. If you want, I can also provide a short guide on how to attach the wooden strips.

Interesting, but I wonder if the issue really comes down to the material thickness alone, or if the design of the shelving unit itself plays a role?
The physical behavior of shelves – specifically, the deflection under load – is often not sufficiently considered. Even if the weight is evenly distributed, thin materials may not hold up over time. Perhaps a completely different type of shelving or material needs to be considered.
It’s also important to check whether the shelf is actually rated for the desired load. IKEA usually provides load capacity warnings, which should be taken seriously.
I would also be interested to know if others here have systematically tested how much weight the shelf can carry before the boards sag irreversibly.

Haha, yes, I think every book lover here knows the BILLY phenomenon 😄 Books can be little weightlifters sometimes!
Honestly, when the shelves sag, it’s annoying but quite normal given the construction. Sure, you can reinforce them with wooden strips or metal brackets, but you can’t completely prevent sagging if the shelf unit isn’t very sturdy.
My advice: Use the bottom shelf for heavy tomes and classic hardcovers, and place lighter decorative items or light boxes on the upper shelves. This way, the shelf has less weight to carry and still looks great.
And yes 🙂 you can add reinforcements, but don’t expect it to perform exactly like a heavy-duty shelving unit.

Hello Taklo56, I understand the issue well and would like to add a step-by-step guide for reinforcing the BILLY shelves to KUDAISY’s suggestions:
1. Check the requirements: Measure the thickness and width of the current shelves.
2. Obtain wooden slats: Preferably pine slats around 12–15 mm (0.5–0.6 inches) thick, approximately 20–30 mm (0.8–1.2 inches) wide, with a length matching the shelves.
3. Installation: Screw the slats with small screws to the front and back edges underneath the shelves. Make sure the screws are as short as possible so they do not penetrate through the shelf.
4. Additional central support: If possible, fix a vertical slat underneath in the middle to significantly reduce sagging.
5. Alternative options: More complex solutions include inserting aluminum profiles or replacing the shelves with reinforced ones, if available from IKEA.
The result will be a significantly increased load capacity and minimized sagging. Tip: Don’t forget to distribute weight evenly.
Feel free to ask if you have any questions.

Who would have thought that my BILLY shelves could spark so much discussion? 🙂
I think the whole issue is really easy to solve with the reinforcements you’re talking about. The important thing to keep in mind is that the shelf is intended for home use and normal loads, not for tons of books.
For me, a simple wooden strip under the shelves worked wonders – and it doesn’t even look bad. You can even paint or cover the strips so that they match the look.
If design is important, you might consider replacing the shelves with MDF or plywood, which is more stable and looks higher quality.
