Review: Excellent - I really wanted a down comforter. I wanted something fluffy and soft and luxurious feeling and looking. Down comforters are usually super expensive but I was on a budget and I didn't mind looking through multiple websites for the perfect item. desertcart was the only place that I could find that had something like this, both high quality and affordable. This down comforter has a 100% cotton shell as well as having down feathers inside. Even the more expensive products don't offer both. This is super comfortable, cute, and has good quality material. I highly recommend this down comforter.
