1. Question: What’s the difference between pillows and cushions which aren’t nullified to the Sukkah in order to make it less than 20 amos high since most people would not want to just nullify their pillow and cushions which are laying in the Sukkah but on Pesach we do say people would nullify chometz even though a lot of it could get expensive like pillows and cushions so most people wouldn’t for such a thing?
Background:
A. Granted there is a prohibition of owning chometz so you would want to nullify it but there is a mitzvah to live in a Sukkah so you’d want to fulfill it.
B. Nullifying is to treat it as the dust of the earth which a typical person would not want to do to his pillows and cushions so the same should apply to a lot of food.
C. The Torah really takes chometz out of your property but puts it back in to your possession to give you a sin but it’s not really yours until after Pesach.
Answer: By chometz you don’t need the chometz itself to be like dust rather just in your eyes it’s like dust so that the Torah takes it out of your property and keeps it out so your knowledge isn’t nullified to everyone else’s. But by the pillows and cushions your attitude has to really be that they are like the dirt of the ground so that it will minimize the space of the height of the Sukkah therefore we say one thought is nullified to what the world would think and they would never treat them that way so the pillows and cushions cannot be nullified.
