A man went to a hospital with his wife who was having surgery. He had been at the hospital for approximately an hour in the waiting room when he returned back to his seat. The individual sat down back in the chair he had been sitting in previously and as he sat on the front of the chair, it collapsed beneath him sending him to the floor. While he initially declined medical treatment, in the coming weeks he discovered that he had suffered serious injuries as a result of the fall resulting in more than $60,000 in medical bills. After consulting with a lawyer, a lawsuit was filed alleging negligence on the behalf of the hospital and the manufacturer of the chair or question.

1. What legal defense(s) would each of the two defendants (hospital and chair manufacturer) likely raise in the lawsuit?
