Hello everyone, I am currently facing the issue that the shelves of my IKEA Brimnes shelving unit bend under heavier loads. Especially the middle shelves seem to only partially support the weight of books and binders. Therefore, my question is: What is the best way to reinforce the shelves of the IKEA BRIMNES unit to make them sturdier and able to carry heavier loads over longer periods? I have already considered adding extra cross braces or metal reinforcements, but I would like to know which solutions are truly practical without significantly affecting the appearance or functionality of the shelving unit. I would greatly appreciate specific tips, experiences, or recommendations for suitable materials.
Hello Leoemil, your concern is very understandable, as the problem of sagging shelves in IKEA furniture is quite common. To reinforce the BRIMNES shelves, I recommend taking a step-by-step approach:
- First, you should find out what kind of load the shelves typically bear (weight in kilograms, distribution of the load).
- Then, you could replace the original shelves with plywood or multiplex boards about 15 to 18 mm (0.6 to 0.7 inches) thick. These are more stable and less prone to warping.
- Additionally, you can screw metal corner brackets (e.g., steel angles) across the underside of the shelves. These significantly increase load capacity and distribute weight more evenly.
- Another option is reinforcement with a continuous crossbar underneath the shelf, mounted on the back of the unit to prevent bending.
A small tip: When drilling, make sure to fix the boards and brackets so that the screws don’t tear out or the edges don’t split. With any reinforcement, the load capacity increases, but installation needs to be very precise to avoid deforming the shelves. Do you also use the space behind the unit or the side panels as potential points for additional stabilization? If you can provide more details about usage and load, I’m happy to assist further.

However, I’m still wondering whether I should add reinforcement to the side panels of the shelf or if it’s better to attach the brackets only under the shelves. How does that affect stability? My concern is that too many metal brackets could look unattractive.
Mounting on the side walls is usually advisable, as this helps distribute the load better and makes the entire piece of furniture more stable. One option is to attach flat metal brackets or strips, color-matched to the shelf interior, so they are barely visible. Gluing the reinforcement strips with wood glue before screwing them in can also provide additional support. It is important that the reinforcements work across the entire width, not just in isolated spots.
