You can do this any number of ways. In the case of this bed I have the edges slope as the logs subside.
On one area of it, though, I have added a very large but somewhat thin stone to the wall in order to allow it to be taller with less slope. It worked very well, and using cinder blocks or stones you could make yourself a nice and neat bed with vertical edges using hugelkultur.
