Premium 100% Cotton Duvet Comforter Protector - King Size - 106" x 86" - White - Breathable 300 Thread Count Hypoallergenic Cover - Zippered Encasement - Bedding Linen

I bought this item after I found out that I am extremely allergic to dustmites. Does it work? I do not know, because I changed all my bedding, bought an air purifier as well and am on medication, but I do feel a lot better in general :). Anyway I wanted to say that the duvet cover feels amazing! It is nice and soft and you can see it is great quality.

good quality and this duvet holds the down feather iINSIDE! should have bought this sooner, made my life so much easier not having to vacuum the room every day cause I could see the white down feather everywhere. I used this duvet underneath my hotel collection duvet.

It serves the purpose of keeping the feathers in the down, comforter that I have inside the duvet, but it’s noisy, like plastic not a big deal, but just so you know

I gave three stars because it’s not really breathable as I got sweaty at night.

I bought this primarily to reduce the number of feathers that escape the comforter and dig their way into my sheets or to the top of the comforter cover, where they stick to any clothing I lay out on the bed. And for that, it works great. If it also reduces allergens, that's just a bonus. Note about sizing: Amazon.ca doesn't carry every size, and Amazon.com carries more sizes but doesn't list the measurements at all, so it was a bit of an annoying process to determine the right size when I bought this. So here it is, right from the packaging of the one I bought: Twin = 66" x 86" Long Twin = 70" x 90" Full/Queen = 86" x 86" Long Full/Queen = 96" x 92" King = 106" x 86" Long King = 110" x 98" My bed is a Queen. My comforter and cover are both Queen, but both are a bit bigger than 86" x 86". And the cover is a bit bigger than the comforter. So there was already a bit of "empty" cover area at the sides, but it wasn't noticeable. My comforter is 90" wide, so when I put it into the cover it became 86" wide. No big deal - it didn't bunch up or fold over, so it must have just stayed thicker. And now there's at least 2" of empty space at the sides of the cover, but again, not an issue - can't see or feel any problem with it. Installation was reasonably quick and easy. The feather madness has almost completely stopped, and I suspect that the few I've seen since installing this were already in the cover from before (I couldn't get them all out). The assembled set (comforter, this cover, and my fake suede cover) seem very slightly heavier and warmer than before, but I like that. The room is cold at night and the warm bed is awesome. I hope this helps someone with their shopping choice. Cheers
