Hello everyone, I have a problem with the shelves from Bobby sagging increasingly despite normal loading. The shelves are standard about 80 cm (31.5 inches) wide and made of relatively thin wood-based panels. I would like to know how I can stabilize or reinforce the individual shelves so they don’t sag any further. What methods are recommended here, are special supports or reinforcements advisable, or should I consider replacing the shelves? I look forward to your tips and experience!

How important is it that the reinforcement is placed exactly in the center under the shelf board?It is actually most effective when the reinforcement is positioned as close as possible to the center under the shelf board. This is where the lever exerts the greatest force, exactly at the point where the deflection is strongest. A strip placed at the front or back provides less reinforcement because it does not optimally support the different forces. Especially for shelves without a central support or reinforcement, the central position is crucial for load-bearing capacity.
I know the problem; sagging is really annoying because you constantly worry that the shelf might get damaged over time. What helped me was actually the combination of a center support and placing lighter items on wide shelves. It’s good that you are focusing on improving stability – it definitely pays off.

Is there a general rule of thumb for how thick the wooden strip should be?Yes, generally the strip should be at least 20 mm (0.8 inches) wide and 30–40 mm (1.2–1.6 inches) high to provide sufficient stability. The taller the strip, the better the stiffness, since bending stiffness increases with the square of the height. For very heavy loads, a metal profile can also be useful. For most Bobby shelves, a 20 x 40 mm (0.8 x 1.6 inches) strip is sufficient.
