Update: since my original review the company has reached out to me and apologized for the quality of the comforter i received. They replaced the comforter with a brand new one and didn't make me send back the old one either! This new one is great quality so i am very pleased. The comforter is super comfy and not too hot or too cold. It has some weight to it which i love because it makes it so much more cozy without making me too hot. I got the super king size and I love how big it is. My husband and i don't fight over the covers anymore. With this new comforter and the way they handled things i give this company and product 5 stars and would highly recommend this to anyone! Well, I just opened this comforter and already im finding issues. There are strings coming out and at least 2 stains I've found so far. Not sure if I should return this or what as I'm sure it would be really hard to fit this back into the case. Wish this was a better experience. This was very expensive too, so very disappointing.
