ᐅ How can I increase the stability of additional shelves in BILLY bookcases?

sinanonHello everyone, I have a few BILLY shelves from IKEA at home and want to reinforce the shelves because I mainly want to stack heavy books on them. My question is: How can I add extra stability to BILLY shelves without significantly changing the appearance or making the assembly more complicated? Are there any specific tricks or materials that work well to prevent sagging? I look forward to your experiences and tips!
Hello sinanon, to increase the stability of BILLY shelves, there are several approaches I’d like to explain in detail. By default, the shelves are made of particle board and have a certain load limit, usually around 30 kg (66 lbs) evenly distributed.
One effective method is to attach an additional strip of solid wood or metal as a support underneath the shelf. For example, you can screw a 15-20 mm (0.6-0.8 inch) thick wooden strip lengthwise to the underside of the shelf. This helps to distribute the weight better and significantly reduces sagging. It is important that the strip spans the entire width of the shelf and is fastened with several small screws.
Alternatively, some have had good results using simple metal profiles (e.g., angle brackets) as reinforcement, screwed into the corner under the shelf. Make sure not to overtighten the screws to avoid warping the shelves.
You can also increase the number of shelves, which shortens the unsupported span. However, this only makes sense if you still have space within the shelving unit. Another option is to replace the shelves with thicker panels, such as 18 mm (0.7 inch) plywood boards, which are sturdier but more expensive.
What kind of load are you expecting approximately? And what does your shelving setup look like? Is the unit freestanding, or is it built into a wall recess, for example?

warrenka5715 Nov 2024 10:11Hello sinanon, I understand well how frustrating it can be when the shelves bend and you worry that the entire unit might eventually give way. I had the same issue with my BILLY shelf and thought about how to solve it elegantly without making it look too bulky.
Maybe it’s also an idea to better secure the shelf to the wall if that hasn’t been done yet? Sometimes that helps improve the overall stability. Additionally, I experimented with some carpet tape under the shelves, which prevents heavy books from slipping and helps distribute the load more evenly.
Reinforcing with wooden strips is a good option, but I understand that it might not always fit aesthetically. Are there any restrictions for you regarding that? I definitely wish you success with this – it really occupied my mind back then. Let us know what you decide.

Hey sinanon 🙂 I had slightly thicker shelves custom-cut for my BILLY bookcases, about 19mm (3/4 inch) plywood, and just placed them in. Without many screws, I simply used the original drill holes. It makes a big difference and looks great!
Also, it helps not to overload the shelves. It’s better to restock more often so that there isn’t too much weight all at once.
And yes, a wooden strip underneath the shelf doesn’t hurt if you feel the shelf is sagging. Sometimes these little tricks are really valuable 😉 Good luck with your project!

Sinanon, one more question: Are the shelves already older and visibly sagging, or is this just a preventive concern so far? Depending on that, it’s easier to assess whether reinforcement is necessary.
