I compared a lot of down comforters before purchasing. The description said Made in the USA which was a half truth.

Wonderful
Size: Cooling Queen, Size: Cooling Queen
I absolutely love these pillows From the very first night, I could feel the difference. They are incredibly comfortable, soft, and still provide great support for my neck and head. Plus, the modern design makes my bed look so much cleaner and more elegant. The fabric feels high quality, and the pillows keep their shape really well. I genuinely feel like I’m sleeping better since I started using them. Great value for the price, and I would definitely buy them again. Highly recommend
