A down comforter (or silk, or down alternative) goes inside the duvet cover, creating the floofy duvet. If you want an oversized fit for your bed, you could order a king size comforter and a king size duvet cover (I seem to remember that there used to be companies who manufactured and sold oversized queen comforters but I don't know how common/easy to find those are nowadays). If you order a queen sized comforter and put it inside a king sized duvet cover, you're going to have a lot of empty space on the sides and around the actual comforter. The duvet cover has to fit your comforter properly. If you want something that's "middle of the road" for warmth, you want to look for an all season or year round weight, not anything marked extra warmth or specific for winter. Look for something in the 40oz./700-750 fill power range for a queen comforter. Answer from helenasbff on reddit.com

January 23, 2024 -

Hi all, long time lurker, reading through the amazing posts by such knowledgeable people. I am looking for a new queen down comforter. Mine is almost 20 years old and flat as a pancake. Something mid- warm. I’d like it to hang over the sides of my queen size bed. Should I get a queen size down insert and a king duvet? What is a mid warmth down fill number you’d recommend? I’m so overwhelmed by all the choices!

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?

As the title says, has anyone bought a down alternative/synthetic down comforter that is not garbage after a year?

Back in August I bought the Pottery Barn Hydrocool down alternative duvet insert.

I am currently a college student and thus funds are limited, however I am a chronic insomniac and have a lot of sleep issues, so a good comforter was something I was willing to splurge on. It was definitely not the most expensive option on the market, but for $150, I didn’t expect it to completely fall apart within 9 months. By the time I moved out of my dorm in May, the filling had bunched up into pockets, leaving parts of the comforter completely flat.

I’m now going back to school for my sophomore year and would like to buy a comforter/duvet insert that will last until I graduate. I have a down comforter at home and it’s my favorite thing, but it requires too much upkeep for college. Wirecutter, The Strategist, etc. all love the Brooklinen, Buffy, Parachute, Company Store, LL Bean, etc. but I keep seeing reviews on the stores’ sites themselves and on reddit that they all have this issue.

So, if anyone has bought an down alternative comforter in the past three years—from one of the brands listed above or anywhere else—that is still relatively intact, tell me!!
