What details of the setting show that the the apartment is crowded

Although it is only a one-bedroom apartment, five people live there. Beneatha and Mama live in the bedroom. Walter and his wife Ruth have converted the small breakfast nook into their bedroom. Their son Travis sleeps on the sofa in the living room, which serves as the dining area in the daytime. The multiple functions of the room present a challenge for young Travis.
