Why do you suppose Chopin does not supply much information in exposition?
The minimalist technique used by Kate Chopin to refer to the setting in her short story "The Story of an Hour" is aimed to place the reader's attention on the theme of the story and on the action itself. It is not totally specified where the action takes place, except that it is at the house of Mrs. Mallard. We also know that the reason why she has company is because she is about to be conveyed the news of her husband's likely death.
Yet, there is one specific setting in the story that helps us understand the contrasts in the life of Mrs. Mallard: Her open window. It is when she gets toher open window that she can see a world of freedom that now be open for her.She regains life and joy as she looks at the world
all acquiver with the new spring life
Therefore, Chopin wants to focus on Mrs. Mallard's role as an unhappy woman inside of her own home, in contrast to the wide open world that exists outside the binding expectations of women in the society of the 19th century.
