That must be regional because we never use term “comforter” here and always use quilt. According to Wikipedia, quilting refers not to the patchwork but to the stitching.
That doesn't change the point that most speakers of the English language will use “quilt” to refer to a patchwork comforter.
The use of this-or-that dialect is just fine when people who use a different dialect recognize the use. But, in this case, most readers won't; so it's a good idea to look for a different word.
