Answer: The woman within the poem is comparing her life to a stair case.
Explanation:
At the beginning of the poem, she immediately states "Life for me ain't been no crystal stair." Comparing her life to that of a staircase with no problems and then explaining her life was far from having no issues.
As the poem continues she explains that "her staircase" has splintered, torn up boards, and bare. These things imply issues she has when living her own life. She uses anaologies such as imperfections and darkness in "her staircase" in order to enhance the comparison to her life or staircase.
