Pillows not exactly down..
Size: Queen (Pack of 2)
I just got the pillows the tag say 80% polyester and 20% inner filling and 70% down and 20 % feather + ? Outer filling.. which is not what is advertised in the title. However AI indicated most pillows are constructed with two layers because of it is all dow it will be flat ... anyway the pillows will be tested after tomorrow as they recommend to leave it for one day before using it..
To be continued later

Great for side sleepers
It always seems hard to find the perfect pillow when you’re a side-sleeper. This one is great. It comes compressed so you will want to allow some time for it to fully fluff back up. The cover is soft and smooth. I love that it isn’t overstuffed. It provides gentle support and a lot of comfort. I was worried it may be too warm since it is polyester, but it is very breathable and I have not had any issues with feeling overly warm on it. It fits a standard size pillow case. It’s not overly stuffed like some other pillows I’ve tried that were specifically for side-sleepers. I think this world be a great pillow for any sleeping position, really. I wasn’t expecting to love a pillow this affordable, but it gets the job done and I get a good night of sleep. I’ll be purchasing some more for our guest room.

Incredibly Comfortable and Supportive — My New Favorite Pillow！
I wasn’t expecting to love this pillow as much as I do, but the DIORIS large sleeping pillow really exceeded my expectations. From the first night, I noticed a difference in the way my neck and shoulders felt in the morning—less tension, better alignment, and overall more restful sleep.
The fill is just the right balance between plush and supportive. It doesn’t flatten out during the night, which is a problem I’ve had with other pillows, especially those that come overstuffed or too soft. This one holds its shape well but still has that cozy, cloud-like feel when you lay your head on it.
I’m a side and back sleeper, and this pillow works beautifully in both positions. It’s also large enough that I don’t feel like I’m falling off it during the night, but not so big that it takes over the whole bed.
One suggestion: if you’re picky about loft, you might want to give it a gentle fluff or adjust the fill before your first night. But honestly, I didn’t need to do much—it was pretty much perfect out of the bag.
Highly recommended if you're looking for a high-quality, comfortable, and generously sized pillow that supports a great night’s sleep!

Hotel like pillow
These pillows were a pleasant surprise. I bought the set for our guest room but ended up keeping them for our own bed after trying them out. They feel incredibly soft yet still provide enough support to keep my neck from feeling stiff in the morning. I sleep on my side and back, and these work great for both positions. My spouse, who usually runs hot at night, said they stayed cool and breathable.
The material feels high quality, and I love that they’re machine washable without losing their shape. They fluffed right back up after drying. If you're looking for that plush hotel-pillow feel with everyday practicality, this set really delivers.

Very soft, not firm at all
This pillow is very floppy and not firm at all. It is quite large and I was surprised at the size. My dog has taken a liking to it and decided it's now her new dig bed, which is fine by me, because it's really too soft for my liking. If you like soft pillows then this is for you. If you require something with a bit more support then you won't enjoy this pillow.
