ᐅ Building Billy Shelf Supports – for Improved Stability?

Hello everyone, I’m thinking about how to make a Billy bookshelf from the well-known furniture store even more stable. I’ve noticed that the standard fasteners – meaning the dowels and screws – sometimes aren’t enough, especially for taller shelves when you put heavier books or boxes on them. In this context, I’ve heard that you can add so-called cleats, which are additional metal or wooden strips, to better support the shelf boards and achieve better load distribution.

My specific question is: Is it worth making and retrofitting cleats on the Billy bookshelf to noticeably improve stability? Or are they rather unnecessary if the shelves are used normally? If anyone has personal experience, I would like to know how this is done in practice, which materials are suitable, and whether it also makes sense for older models. Thanks in advance for your opinions and tips!

Hello, supports are a good idea if the shelves visibly sag or if you want to carry more weight. Simply screw wooden battens just below the shelves; that is usually enough. Otherwise, the original brackets are generally sufficient for everyday use.

Hello Langkin, your question is very good because stability is often underestimated with Billy-style shelves. The shelves are usually made of particle board, and depending on the width, they can bend under heavy weight.

Additional supports, such as wooden strips or metal brackets attached underneath the shelves, greatly improve the load-bearing capacity. By reinforcing and better distributing the load, the shelves become not only more stable but also more durable.

For materials, sturdy woods like beech or spruce work best if you are working on a DIY basis. Metal brackets are also strong but more complicated to install and less visually appealing.

For older models, it often makes sense since the material may have settled over the years. The most important thing is that the supports are properly screwed to both the shelf and the vertical frame to prevent tipping.

Personally, I definitely recommend trying this for shelves that will bear heavier loads.

I see it differently. Adding supports is more of a symptom of a suboptimal design. If a Billy shelf needs supports to be stable, that’s not necessarily a plus for the product – it shows that the design is reaching its limits.

One could also ask: wouldn’t it be better to invest in a better-designed shelf from the start, rather than fiddling with supports? Of course, I understand the DIY approach, but sometimes it pays off to think outside the box. If the shelves are really too unstable, it’s often more effective to reduce the load rather than reinforce the construction.

If the shelf needs to be more stable, supports are advisable. Alternatively, you can install double back panels or fix the shelf board to the wall using brackets. This will hold everything together more securely.

I am quite familiar with the problem of sagging Billy shelves and often felt unsure whether the shelf would still hold, especially when loading heavy reference books.

Sometimes I tried to encourage myself, but the doubts remain. That’s why I find such supports quite practical, as they provide a sense of security.

It’s also reassuring to hear that this weak point can be fixed with simple measures. In my opinion, you shouldn’t be discouraged by apparent weaknesses but rather learn how to improve them.

Perhaps we could also discuss longer-term experiences with different types of shelf supports here? That would certainly help me and others.
