I used a polyester batting for a quilt for my daughter's bed in about 1976 when she got her first big girl bed. She used it and we washed it regulary until she got married. Now her daughter uses it on her bed and it still is soft and comfy. It is hand quilted because that was all I knew how to do back then. I think you can use anything you want and if you do a good job of quilting it will last a long time.
