ᐅ How can bending be prevented in IKEA Brimnes shelves?

Hello everyone, I have been experiencing an issue with my IKEA Brimnes shelves for some time: after a while of use, they start to sag, especially the middle shelves under load. I have already made sure not to overload them, but this does not seem to prevent the problem. Therefore, I am interested in possible ways to effectively avoid sagging in Brimnes shelves. Are there any recommended reinforcement methods or specific tips that could help? I look forward to your ideas and experiences, including any advice on materials or assembly techniques that might make a difference.

It is best to distribute weight evenly and avoid storing very heavy loads in the center. An easy solution is also to add additional central supports or thin wooden battens as reinforcement behind the back panel.

Hello LEFEGO, your concern is typical for shelves with relatively thin chipboard shelves, as often used with Brimnes. These tend to sag over time under load, especially if the weight is concentrated rather than evenly distributed.

I recommend the following measures:
- Distribute the load as evenly as possible, avoiding large stacks directly in the middle.
- Use additional shelf supports or a center beam underneath the shelf if the design allows it.
- You might also attach special angle brackets to the underside of the shelf to significantly increase its load capacity.
- Sometimes adding a reinforcing panel to the back can help, as the back panel greatly improves stability.

If possible, also check whether the shelf has been assembled correctly on site and tighten all screws, as this will further stabilize the whole unit.

Hey, I also had issues with Brimnes shelves! 😊 My tip: place simple wooden strips underneath the shelves as support! It makes a big difference and is really easy to do. Try it out—you’ll notice the improvement immediately! 💪

Regarding sagging in IKEA Brimnes shelves, the following can be stated: The shelves in the Brimnes series are typically made from 15 mm (0.6 inch) particleboard with a melamine coating. This material thickness is designed for moderate loads, but the load-bearing capacity decreases under high point loads or prolonged stress.

To prevent sagging, I recommend:
- Using metal profiles or wooden slats as horizontal reinforcements beneath the shelves.
- Adding additional center supports, if necessary installing a support beam through DIY.
- Ensuring even load distribution to avoid localized overloading.
- Checking the assembly; protruding or loose fasteners reduce stability.

Alternatively, replacement shelves with greater material thickness or MDF boards can be considered if longer durability is desired.

Reinforce the shelves at the bottom with suitable wooden strips or aluminum profiles. This effectively prevents sagging. Central supports or additional shelf dividers also help.
