Hi Claire,
Thanks for taking the time to leave a review. We are sorry to hear the comforter was not what you were expecting.
Just to clarify, the Stripe Driftwood Comforter is not advertised as cotton. It is made from a smooth microfibre fabric and designed to be lightweight and thin, more of a comforter or bedspread style rather than a thick quilt or doona. This is outlined on the product page, including the fabric composition and intended feel.
Microfibre will feel very different to cotton, and because it is lightweight, it can crease more straight out of packaging. A wash and light air dry usually helps it relax and smooth out.
That said, we understand comfort and fabric preference is personal, and we appreciate you sharing your experience as it helps other customers make an informed choice.
