I wash my quilted purses/totes when ever they need it- toss them right in the washer & dryer with everything else...but they are quilted well- just like a quilt- with the same types of battings. I would guess it depends on how it is quilted & what batting is used- I have a quilted wallet I purchased years ago that has been washed a few dozen times too- I've never had any problems with it- but I wash/dry all of my quilts too. to me if I can not wash/dry it It's pretty worthless in my world.
