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

Anyone have a truly plush down alternative comforter that sleeps cool?

Simmons down alternative blanket - how warm?
It’s pretty warm. Good for winter, a bit warm for spring/summer. I’m still using mine. And it should be comfy with AC More on reddit.com

Are expensive down comforters worth it?

That depends on what your standard for "worth it" is. Bedding, for me, goes into a category where frugality takes on a different aspect. I'm not just looking for the lowest price, I'm looking for the best that I can afford. It shows in my bedframe, my mattress, my comforter...

If you live in a colder climate, then it's absolutely worth it. I have a down alternative comforter because I live in the subtropics, but even though I'm rocking a $60 Amazon comforter in a $25 duvet, it's an unbelievably gully pleasure to cozy up under a fluffy blanket at the end of the day.

A quick search in r/BuyItForLife will show that the selection carried by LL Bean is well loved.

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?
