Folks, this is Good. I was rather skeptical, seeing the price and thought... If nothing else, it will be my backup blanket on the couch. Quality. Real down feather. White color is really white. It is heavy and not patchy like some of the cheaper ones are. You can feel the weight of the feathers on your body. Needs a duvet cover. The blanket itself is not at all as soft as I had expected. My old father down blanket felt like satin sheet this one... You are very aware you are under a blanket. Other than that small detail... This is Good quality. I recommend. It also feels like it will withstand machine washing.

This is everything you want in a down filled duvet insert. Perfect weight and square panels is no nice to the stuffing does not end up bunched up. The loops in the corners is also nice to attach your duvet cover. Very happy with this purchase. Bought multiples for gifts and myself.

The Over Sized King fits my King Sized 15” Memory Foam Mattress Bed perfectly. I found it was quite wrinkled beings it was tightly vacuum sealed. I put it in my dryer on cool dry for about 10 minutes then my Hubby and I loosened each stitched box of down and the we shook it outdoors to fluff it up. For the remaining deep wrinkles I used my hand held clothing streamer to remove any remaining wrinkles. I purchased the dark grey and I found depending on the lighting the fabric changes the shade of grey. It’s made of beautiful thick soft cotton fabric. The stitching appears perfect. It has 8 solid loops for a duvet cover. Weight on the oversized king box notes it is 8.9 pounds. The fabric is crisp so when you climb under it it creates a poof bubble around the body and it hold the perfect temperature :) I do not like heavy covers weighing down on my body, this comforter feels perfect :) I purchased the Oversized King on Amazon Prime week for $69.00 Personally I launder my large comforters at the laundry mat as I refuse to stress my front load washing machine. Grey to use as a comforter this on Amazon Prime very happy wi

Perfect weight, keeps me warm but also not too warm in the summer heat. Feels like it’s breathable while keeping me a good temperature at night. Only downside is feathers poking out all the time

Excellent comforter. Nice weight. 8 tie downs to secure inside duvet cover. Little crinkly sounding but I prefer that. Super comfortable and soft. I am very happy with this purchase.. Excellent price 👌

Really like this comforter, but be careful. It may require dry cleaning if it’s natural

I have an Eastern King bed, it’s wider than a Cal King. And this down comforter is the absolutely perfect size for it! I wanted a comforter that covers all sides of the bed down to the bedskirt, since all the others ones I’ve had only barely come down halfway past the sides of my mattress showing the sides of the bed sheets. I got the oversized king one and it’s perfect! Also keeps my husband and I warm at night but not overly warm. I laid it out after removing from package for 24 Hours and gently padded it all over with my wooden back scratcher to help it fluff up nicely. So happy I purchased this beautiful comforter and great price!!!!
