Hello everyone,
Some time ago, I bought a Billy bookshelf from IKEA and noticed that the shelves noticeably bend under moderate weight, which affects both the overall appearance and stability. According to the product description, the shelves are 16 mm (5/8 inch) thick and made of medium-density fiberboard (MDF) with a melamine resin coating. There are no extremely heavy items on them, mostly books and some decorative objects, but nothing excessive.
My question is: What options are available to prevent or at least significantly reduce the bending of the shelves? I have read about some people supporting the boards differently or adding extra reinforcements. But are there also simple, practical solutions or recommendations for alternative shelves that would fit?
I would appreciate any helpful tips and experiences!

Hello flose,
I know this problem very well—I have the Billy shelf at my place too. The sagging of the shelves is almost notorious, especially when you put a lot of books on them. My tip: simply screw additional wooden slats (e.g., spruce slats) underneath the shelves. This not only makes them more stable but can also look nice if done neatly. 😊
Or, if you prefer something more modern, metal profiles from underneath. It doesn’t cost much and really looks good.
Good luck!

Simply screw additional wooden battens (e.g., spruce battens) underneath the shelves.Absolutely! And if you countersink the screws properly, it almost looks like a design feature. 🙂
It also helps to avoid loading the shelves fully to the edge. Often, the weight shifts outward, causing the shelf to sag most in that area. With a bit of stacking strategy, you can make a big difference!
Hello flose,
The issue of shelf sagging is unfortunately well known with Billy shelves. The standard MDF panels are simply not designed for heavy loads. If you cannot change the shelf thickness, I recommend distributing the weight across several shelves, meaning placing fewer heavy books on each shelf.
Another option is to reinforce or additionally stabilize the back panel of the shelf to reduce warping. It also helps to fill the shelf completely to the top, as this increases overall rigidity.
If you are handy, you can screw L-shaped metal strips under the shelves, as LUKO45 already mentioned—this really works well.
One more tip: Using packing material like cardboard between the books can help prevent localized pressure points.

What options are there to prevent or at least significantly reduce the sagging of shelves?The fundamental issue is the load-bearing capacity of the shelves used. The simplest and most effective solution is to install structural reinforcements. These can be metal brackets or hardwood strips attached underneath the shelf edges, which greatly reduce sagging.
Alternatively, you can use shelves made of beech plywood of the same thickness; this material is significantly stronger and less flexible. The disadvantage of higher cost needs to be considered.
With regard to weight, it is also important to note that the manufacturer’s stated load limits are about 15–20 kg per shelf (33–44 lbs). If you exceed this, the shelf will definitely bend.
