Well for one after purchasing numerous comforters over the years. I always want to congratulate the photographers who takes the pictures. It will never look like that, turn with that said it was exactly what I wanted, and lived up to the purchase. I like the crunchy sound, I use a duvet cover with it. For me it’s like sleeping on a cloud. Perfect weight, feel and texture, yes it does have a bit of feather smell, but it will dissipate . For the price it’s great. If you’re looking for one that looks like the picture and with total goose down , go to a high end store and you will pay a lot. No duck feathers are poking out or stabbing me. This was a good buy.

This duvet is awesome. It feels soft to the touch, has plenty of loft, and strikes the perfect balance of warmth, but not too hot, not too cold. It’s truly 4-season ready and works well whether the nights are cool or on the warmer side. I’ve owned more expensive duvets in the $400+ range, and this one feels just as good, if not better, at a fraction of the price. The quality and comfort exceeded my expectations, and it fluffs back up nicely after a quick run in the dryer before use. Overall: A cozy, well-made duvet that delivers luxury comfort without the luxury price tag. Highly recommended.

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.

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

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 media could not be loaded. I purchased this all season “Feather down Fiber” comforter last week, queen sized, thinking it’d be just in time for the cool fall season. Down comforters are supposed to be big & fluffy almost resembling or feeling what you’d compared to a cloud. Which is exactly what’s shown in the picture description listed to entice sales. Unfortunately this was a HUGE disappointment. It came packaged in a vacuum sealed bag with directions to let it lay out, patting for full expansion. Once opened, I released it onto my bed while I would be away at work. Returning home after 15hrs, it was the same flimsy spread. It puffed up ever so slightly but for the most part it resembles & even sounds like a tarp. After checking the manufacturers label, I realized the inner stuffing material are primarily duck feathers. Duck feathers would never give the true down feather feel or look. I cannot speak to the sleep quality or wash ability because I’m returning it within 24hrs of having it but I’d imagine it’d be an decent blanket for colder months because again, as I said the material feels & sounds heavy like a tarp. Myself personally, I dont find this material to be comfy or cozy even if I were to put a bamboo duvet cover over it. I patted it out & shook it hoping to give it life but its still looks like a crumpled up piece of paper. I folded it up & placed it right back in the box it came in- a true goose down comforter, wouldn’t be able to do that. Don’t waste your time or money. I’ll have to go in store to feel the materials next time I’m purchasing comforters.

I have been shopping for a new down comforter for quite some time. I’ve tried several major brands only to be disappointed in the quality. My new comforter is amazing. The feel of the fabric, the look is just what I’ve been looking for.

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.
