That sounds odd. A cupboard with an upward sloping floor.
Couldn't you have had built in shelves that you could get to from the side (i.e. in place of the partition).
Built in drawers on rails inside? Few boxes on rails. Attach a rope to them so you can get them out when they're at the back...? Basically hide junk and spare bedding at the back if you don't need to use it often.
As you say, going to be pretty awkward to use the back of a cupboard that doesn't have a flat floor...
Drawers that slide out from the (currently partition) side would be better. Then they won't end up too deep (although you may struggle with accessing the very top ones. Maybe box in the top half and turn it into a cupboard?
