The answer is pretty simple, but probably not SO obvious:
Mounting your new IKEA Stolmen!
The apartment is starting to get filled with new furniture, but it takes time.
2 days of 2 people were not enough to finish, but at least we installed all the poles and part of the shelves. We still have a couple of drawers to mount and then we’ll be able to fill it with clothes.
I took some pictures, but it’s hard to render the idea of the spaces, I will try to attach them and see if it makes any sense.
