Attach Ikea Pax wardrobe to the wall

Hello,
finally I am also in possession of a lot of Pax parts. There were also few problems with the assembly.

But I do have one question: How do I attach a 200/100/60 cabinet (hinged doors are to be installed later) to the wall?

The problem is that the cabinet has a 6 cm gap to the wall because of beautiful old building baseboards. Cutting out recesses for the baseboards on the cabinet is unfavorable because the baseboards are about 20 cm high. I would have to cut away too much from the side panels. I also cannot remove the baseboards as there are already shelves in front of about 3 m of them. I’m also not really keen on remodeling half the apartment just because I want to assemble a cabinet now.

Additionally, the floor is very uneven. This means it slopes down from the wall into the room by quite a bit, so the cabinet practically only stands on its two front feet. That doesn’t inspire much confidence in me, so I would like to attach it to the wall.

How did you do it? Does anyone have an idea?

The cabinet should not stand solely on its feet, otherwise there is a risk that the bottom panel will break out. There is a discussion about this in another Pax post. This means you should support the sides. If no drawers or anything else that shifts the cabinet's center of gravity outside the footprint are installed, I do not consider it necessary to anchor it to the wall. Others may see it differently. If you still want to secure it and the carcass stands firmly on the side panels, then using very long screws should be sufficient. If you want a fastening that secures the cabinet in all directions, the very long screw must go through, for example, a wooden block that compensates for the gap between the cabinet and the wall. Especially in old buildings, the correct choice of anchor is naturally important.
