Slaves had terrible living conditions. Many of them lived in one place, and that place was filled with many areas for wind to slip through, leaving it consistently freezing and uncomfortable.
They worked for incredibly long hours with little rest and no reward. Even the women and children had to do manual labor and the like, despite the fact that women and children of a different skin color never had to.
Meanwhile, the owners of the plantations that the slaves worked on, had very little worries. They had good food, a warm house, and comfortable clothes along with good furniture. The contrast couldn't possibly be greater.
