Because the STÄLL features only two front legs, wall anchoring requirements are absolute. The cabinet cannot balance under its own weight on the floor. Unanchored, opening a single loaded drawer transfers the center of gravity forward, causing the unit to fall immediately.
IKEA supplies plastic wall plugs and screws in the box, but relying on standard expanding drywall anchors into hollow 1/2-inch gypsum board creates a major structural risk. Over months of use, pulling down on the tilt-out compartments exerts continuous leverage and outward pull against those mounting points.
Mounting the rear ledger rail directly into at least one wooden wall stud using heavy-duty 2.5-inch cabinet screws provides the most secure anchor. If the studs in your hallway do not align with the pre-drilled bracket holes on the frame, drill new anchor holes through the solid back brace, or secure the drywall points with 1/8-inch or 3/16-inch steel toggle bolts. A properly anchored STÄLL should show zero flex or pull-away along the top edge when all four drawers are opened simultaneously.
