What would be the expression to describe making something "not unpleasant"/"less unpleasant"? Specifically, not making it pleasant (adding comforts) but minimizing the expected discomforts.
Let's say, a convict is being put in prison. The stay will not be pleasant, that much is known, but the guards learn facts that make them feel sympathy for the convict, so given the little wiggle room they have, they will try to make it as non-unpleasant as possible.
