Hello everyone, I am currently planning to build a sturdy table frame for my Malm desk, as the original frame seems a bit unstable and I would like it to be more robust. I want to focus primarily on stability without changing the appearance too much. The desk will be 140 cm (55 inches) wide, so the frame needs to be correspondingly strong. My specific question is: How can I make the Malm desk frame more stable? Which materials and structural measures are recommended to prevent wobbling and sagging? Are there any proven techniques or reinforcements that work particularly well? Thanks in advance for your tips!

It is important to align all connections exactly at right angles. Incorrect installation can quickly cause instability. Use screws with washers to avoid damaging the wood. Steel angle brackets are a simple and cost-effective solution to significantly strengthen the frame.

To add to my explanation, I would like to mention: If the chipboard is very thin, it can be useful to screw the central support onto an additional wooden panel that is glued to the underside of the tabletop. This layer absorbs stress and significantly strengthens the screw connections.

Also, check whether the table legs are flexible enough to compensate for slight unevenness in the floor. If not, adjustable feet or felt pads for leveling should be a must.

How much weight do you realistically plan to put on the table? Designs for light office work look different from workbenches or craft tables that need to support heavy loads.

Hello Dutufa, I agree with the recommendations so far and would like to add some points about load distribution: A large bearing surface and even force distribution are key for stability.

If you work with metal profiles, I recommend using rectangular or T-shaped profiles, as these cross-sections have high bending strength. Also, make sure to use sufficiently large and long screws for the connections and pre-drill the holes to avoid material cracks.

If you want to keep the appearance unchanged as much as possible, reinforcements can also be installed on the inside edges of the panel, where they are hardly visible. Ultimately, the combination of sturdy materials, good connection techniques, and precise planning is crucial. If you like, I can also send you a drawing showing how such a reinforced frame could be constructed.
