IKEA Algot storage wall spacers.

The Algot wardrobe frame system has nice brackets to screw to the wall. They even supply extra spacer blocks that are reversable to fit different wall or skirting...but...
I have 230 year old walls that do anything but go straight up.
These spacers fit into the Ikea spacers to make up the gaps (5, 7 and 10mm).
I also have sloping floors - so I needed to make small feet extensions as the supplied adjustable feet just don't have the length for my lowest point.
