I have an alpaca wool insert. I also love big fluffy blankets, but was struggling with temperature regulation and couldn't get down because of allergies. I spent a LOT of time searching on here. I was originally resistant to the alternatives to down/down alternative (silk, wool), but i freaking LOVE the alpaca wool insert. It is SO breathable. I didn't realize what I was missing. I couldn't go back to synthetic fibers because they just trap heat like crazy. It is definitely not as fluffy as down, but it is much fluffier than silk, it has nice weight, and i have layered it with nice cotton blankets. Someone else mentioned linen covers - I also have this on the insert, and think it helps quite a bit with breathability also. Answer from LittleEarthVisitor on reddit.com

r/Bedding on Reddit: Anyone have a truly plush down alternative comforter that sleeps cool?
September 19, 2024 -
My title probably covered it all. No matter how low I turn my AC, I wake up sweating. My current comforter and duvet aren't great and I think both have polyester.
I'm an animal lover and can't support down or feather but I really miss the super plush company store down comforters my best friend had when we were kids. Basically I'd like it as plush as possible but not hot.
Does anyone have something like this that they can recommend?

I have one called downcool off of Amazon it's really lightweight. If I put a duvet cover on it, it's too warm and have to sleep with a/c at 68. I gave up and just use it without a duvet cover and can sleep comfortably at 70-71. Edit: Soo why are people downvoting for me for sharing what bedding I use 😑

r/Bedding on Reddit: I WANT THE FLUFFIEST OVERSTUFFED MONSTER OF A COMFORTER POSSIBLE
February 7, 2024 -
So I just bought a new bed and I’m finally able to make my floofy dream cloud come true.
However, all the comforter/quilt/duvet inserts I’ve looked at look like sad, pathetic, gangly slices of depression and I would really love to be able to jump onto cotton candy and fucking sunshine!!
Does anyone know how I can achieve this? I don’t care about it being warm or what it’s made of I would just like it to be crazy fluffy and soft.
Thanks!

Follow anyone on insta who mainly posts about decor (then more will be suggested). Most of them link to Amazon and have a post about ‘how I achieve super fluffy bedding’. It’s usually a select set of Amazon inserts/quilt, and often stuffing 2 in one duvet cover.

April 23, 2025 - Available in two warmth levels (all season or extra warm), our team found this down alternative comforter to be smooth, pleasantly fluffy, and noise-free when moving around in bed (a bonus if you bed-share with a partner). There was also no odor upon opening it and sleeping with it. While wrestling a duvet insert into a cover isn’t always the easiest task, this comforter was simple to get in and out of its cover.

I’m team “use 2 in the duvet” if you want maximum cloud fluffy bed fulfillment. It’s the easiest option. I have a duvet from Ikea that I’m quite happy with, and if I doubled it, it would be insanely fluffy in the cover 🤷♀️

Look at Quince. I haven't tried their comforters but I have a down alternative pillow from them and love it. They have really great prices, the shell is 100% cotton, and they have a 365 day trial on their bedding items. Just make sure whatever you get has a 100% cotton shell for more breathability.
