What does the chiffarobe symbolize in the novel To Kill a Mockingbird?

In my scholarly reading of literary criticism about
To Kill a Mockingbird, I have never come across a definitive,
well-agreed to comment on this.

The references to the
chiffarobe occur in both Tom Robinson's testimony and Mayella Ewell's testimony. As Tom
references this piece of furniture he reports that Mayella had an item on top of the
chiffarobe and she asked him to get it. He has also been asked to bust up a chiffarobe
in the past.

Mayella reports that the day in question was
the day that he had intended to come bust up the
chiffarobe.

Thus, on an interpretive level, I look at the
chiffarobe in two ways. First, I see it as a symbol of confusion. The piece of furniture
has a door like a closet, but drawers like a dresser. It is like it can't decide what it
is. During the trial, Mayella struggled between keeping the truth and her rehearsed lies
straight in her head. It is also in these moments with Tom that she is trying to assert
an identity, other than the one she has.

Another way to
look at it is that the chiffarobe is a doorway. This is a doorway that Mayella walks
through when she is feeling ready to commit social crimes.
