I bought a 4′ x 8′ sheet of OSB board, around $6.00 at a lumber store and had them cut it into 2′ x 2′ squares. Then I wrapped it with those cheap insulating fiber blankets, and the decorator fabric, I used hot glue to secure it because I was being lazy, but you could use staples. Hope that helps.

I got the comforter at TJ Maxx few years ago, and I don’t know what brand it is, but I have seen similar quilts on Pottery barn or West elm, here is a link to one: http://www.westelm.com/products/hillside-quilt-and-shams-b550/?pkey=cduvet-covers-quilts
