    • Good quality, great feel and very comfortable
Color: Grey/All Season Size: King
I loved it but my wife took and put it away because we didn't have a cover for it so I only got to use it once. But as far as the comforter it was really nice it was soft and heavy for a thin blanket it was just right

    • Perfect down comforter
Color: White/All Season Size: King
Same as described ，amazing value，This is lightweight but efficiently warm for winter time. I also think the lightness of this will be good for summer time comfortable sleeping as well. I have bought high end bedding over the years that cost far than what I paid for this king down comforter insert. It fluffed right up. No bad smells. Definitely breathable. High recommend! ... show more

I really like the duvet it has a nice weight to it and it's fluffy. It did have a smell when first opening it, I had to leave it outside for a day to air it out. With my duvet cover you can see the squares of where the feathers are from a certain angle but overall I'm happy with it

This is perfect for kiddos, the size is accurate to a twin, I bought 3 all in black. I've had zero issues with them fitting a duve cover on them and staying on. The color is true to theboucure. They are comfortable, and the quality is great! They are not overly thick but will keep you warm (not hot or cool). They are easy to use. However the one down fall- when I read “feather down” I was expecting more of a fluffy duvet that feels more like a air hug like the others I had growing up. That was not the case. It's more like a normal comforter that you can place a duvet cover on. It feels more like cotton stuffing then feather stuffing. So if you are looking for the more traditional feel, then this is not for you. ... show more

    • Soft, Fluffy, and Comfortable
Color: White/All Season Size: King
This comforter is very soft and fluffy and feels like hotel-quality bedding. The medium warmth is perfect — warm enough without being too heavy or hot. It fits my king-size bed well and looks clean and cozy. Great quality for the price. Very happy with this purchase.

    • Full and Fluffy Duvet
Color: White/All Season Size: Queen
Just what I wanted: a comfy, fluffy, heavy, down duvet. Has the nice "crunchy" feel only a down duvet can have. It adjusted to my temperature. May have been on the warm side for me, but perfect for leaving the window open a crack during the winter months in NY.

    • Good Comforter
Color: White/All Season Size: Full
It's a crisp white. It makes lots of noise. It's thinner than the image portrays, even after puffing the squares and letting the it sit for hours. Good enough for a budget buy but perhaps not for premium desire. I wouldn't say it's ultra soft but that doesn't matter because it goes into a duvet.
