There are MANY reviews for this pillow!  Most speculating what it's made of, and HOW it's made! 
When receiving it I had the same questions; to be kind, it is an unusual pillow! 
I actually took apart the pillow to answer the questions.  It is NOT made of cardboard, nor is it a carpet sample.  The shaggy side has a stiff, sizle type, of backing which is rolled on all the edges, making it even stiffer.  It is, however, stuffed with a small amount of the usual soft fiberfill.
Now, those of you who've been disappointed (even angry) as I was, BUT know returns are hardly worth the effort, use the pillow as a "sit upon"!  I sew, SO, my deconstructing the pillow, unrolling the edges, and REALLY stuffing it may make it
moderately acceptable!!!
Wayfair, EVERY review for this pillow has been negative!   PLEASE remove this product, it really messes up your reputation! 
Up until now, EVERYTHING I've ordered from Wayfair has been very good quality, an excellent value, and much appreciated!
