ᐅ What is the best way to secure Ikea Platsa units to drywall?

Hello everyone, I am planning to mount an Ikea Platsa cabinet system on a drywall partition and want to find the best method that is secure and long-lasting. Since drywall partitions are not as load-bearing as solid walls, I am looking for a solution that can reliably support the weight of several Platsa cabinets. I am especially interested in recommendations on suitable anchors, screws, possible reinforcement behind the wall, and installation procedures. Does anyone have experience or examples of how to mount Platsa cabinets particularly securely on such walls? I would appreciate detailed tips, as I want to get everything right from the start.

As a general recommendation for installing Platsa on drywall partitions, follow this approach:
- First, check the wall structure to identify where metal studs or wooden studs are located behind the drywall panels.
- Then, whenever possible, screw directly into the studs, as this provides the best load-bearing capacity.
- If no studs can be hit, heavy-duty anchors designed specifically for hollow ceiling or wall types (e.g., metal hollow wall anchors or toggle bolts) should be used; these expand behind the panel.
- The screws must be long enough to engage at least 40 mm (1.5 inches) of the stud behind the drywall.
- For heavier loads, an additional wooden batten or solid wood panel can be fixed behind the drywall. This reinforces the wall and distributes the load over a larger area.
- Before mounting the Platsa elements, carefully measure the positions and install the wall reinforcements accurately. Ultimately, the key is to transfer the load as directly as possible to the load-bearing studs. For example, I recommend using 6 x 50 mm (1/4 x 2 inch) particle board screws combined with metal stud profiles.

I agree with that. Simply clamping to the stud profiles is often too unstable for built-in wardrobe walls, especially when multiple units are installed side by side and used regularly. A wooden reinforcement behind the panel (e.g., an 18 mm (0.7 inch) thick OSB board or plywood) securely supports the load. The panel can be attached to the metal studs with several short screws, and the wardrobe units can then be screwed onto it. This way, the weight is distributed evenly and the drywall is not overloaded. As alternative hardware, I often see metal hollow wall anchors like "Molly" bolts used, but these are usually only recommended for lighter loads.

Thanks in advance for the advice. In my wall, I have standard metal stud profiles that are 60 mm (2.4 inches) wide, spaced about 62 cm (24.4 inches) apart. Behind the drywall, there is only this metal frame. I am considering whether I can attach the cabinet directly to the profiles. Would a 4.5 x 50 mm (3/16 x 2 inch) stainless steel screw and metal hollow wall anchors be sufficient? My concern is that due to the height of the cabinet (about 1.8 m (5 ft 11 in)) and the resulting leverage, the screws or anchors might pull out. Therefore, I would appreciate tips on the best way to distribute and secure the load.

The topic of load-bearing capacity for Platsa cabinets mounted on metal stud profiles in drywall partitions is complex and requires a detailed consideration. In general, metal profiles made from 0.6 mm to 0.7 mm (0.02 to 0.03 inches) thick steel sheet are not designed to support very high loads with just single-screw fastening. The tensile and shear strength of an individual screw in the profile wall is limited, and the leverage forces from a 1.8 m (6 ft) tall cabinet can cause the screw to pull out.

Therefore, I recommend a multi-step approach:
- Stable wooden substructure: Screw a strip of 18 to 24 mm (3/4 to 1 inch) thick spruce or pine wood, pre-drilled with a countersink, directly to the metal profiles using special metal construction screws (e.g., 6 x 50 mm (1/4 x 2 inch)). The number of screws should be sufficient, approximately one screw every 30 to 40 cm (12 to 16 inches) per side of the strip.
- The wooden strip serves as a load distribution surface on which you can then fasten the Platsa elements. Use chipboard screws (5 x 50 mm (3/16 x 2 inch)) that hold well in wood.
- Typically, it makes sense to mount at least two such strips horizontally: one at the lower height and one approximately at the midpoint of the cabinet, to distribute the load and minimize tipping moments.
- Check the existing metal profiles for structural suitability and fastening options; with very thin profiles or wide spacing, the wooden construction helps transfer the loads.
- Make sure that the drywall underneath can bear the weight freely; it may need to be reinforced with backing plates to prevent tearing or damage.

Your concern about leverage forces is justified, so this combination of wooden strips plus metal construction screws is the safest option.

Attach directly to metal studs using strong screws, then screw Platsa onto wooden battens – this is how I have done it for years. Screw length should be at least 50mm (2 inches); use plywood or OSB battens.
