Hello everyone,

I recently bought a Billy shelf from IKEA and am generally satisfied with it, but the way the shelves connect to the side panels didn’t seem optimal in terms of stability. Specifically, the dowels fitting into the pre-drilled holes don’t hold very firmly on my shelf, which causes it to feel a bit wobbly under load.

I’m interested to know if anyone has experience with improving the connection method for the Billy shelf to make it more stable when assembled. Are there any practical tips or alternative materials to create a firmer and more durable connection between the parts? I want to avoid the shelf sagging or becoming unstable over time.

Looking forward to concrete suggestions and experiences that really help, thanks!

Hello Jonrosa,

I would first recommend using wooden dowels instead of plastic ones. They usually hold much more firmly. You can also apply wood glue to the holes before inserting the dowels, which significantly strengthens the connection.

Best regards!

Hey Jonrosa,

I completely understand what you mean—wobbly shelves are really annoying, especially when you want to put a lot of items on them. What helped me was adding small corner braces on the inside corners. It feels much more stable, even though it takes a bit more effort to build.

Sometimes the feeling of insecurity with furniture is bigger than the actual risk ;-) Still, a solid shelf is just more reassuring. Try this method, it helped me sleep better at night.

Thanks for the tip about the wooden dowels! What exactly do you mean—just replace the plastic dowels with wooden dowels of the same size? Has anyone tried that exactly?

About the angle brackets: Do you mean simply screwing them inside the corners? Could that affect the appearance? I want to keep the shelf looking as clean as possible.

Back to the type of connections—I’m also curious whether screw connections instead of dowels are even feasible without damaging the shelf. What do you think?

Regarding improving the connection method of the BILLY shelf – here is a concise analysis with practical recommendations:

The standard plastic dowels combined with particleboard generally provide only moderate joint strength. This is due to the material and the size of the glued surfaces.

1. Use wood glue: Before joining the wooden dowels, always apply standard wood glue. This creates a durable adhesive bond.

2. Wooden dowels instead of plastic: Replace plastic dowels with wooden dowels of the same diameter. These offer better adhesion and swelling behavior.

3. Reinforcement with metal brackets: To increase stability, especially for larger or heavily loaded shelves, small metal brackets (preferably stainless steel or galvanized) should be used inside. Screws should be chosen with the appropriate diameter to avoid material splitting.

4. Screws as an alternative: Screw connections instead of dowels are possible, but care must be taken that the screws are not too thick and fit the pre-drilled holes. Pre-drilling into the side panels and shelves makes this easier and prevents splitting.

Finally, it should be mentioned that careful insertion, gentle tapping, and proper alignment significantly strengthen the overall structure.

Conclusion: The combination of wood glue + wooden dowels + optional metal brackets is a cost-effective and stable retrofit solution.

I believe most people vastly overestimate the stability of the standard BILLY shelf connections.

I agree with the expert here, but honestly: who wants to turn their BILLY into a high-tech wooden piece of furniture? The shelf is affordable and functional, nothing more.

It only becomes truly stable either with a metal frame or very strong connectors. Small brackets on the inside are a nice idea, but not exactly attractive. If you want stability, it’s better to buy something else or build your own.

Or you accept that BILLY is not designed for heavy loads and don’t stress about it. Those who overdo it lose sight of the simple concept.
