If one insulated a pot in a container filled with muktzeh fleece and later removed the pot, may one return it if the hollow remains intact or not?
Synopsis
Returning an insulated pot on Shabbat is permitted only if the hollow in the insulating material remains intact after removal. If the hollow collapses, it is forbidden to return the pot because doing so would require disturbing the muktzeh material. One may remove the pot with intent to return it even without certainty the hollow will remain.
