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!

How do you fluff a down or down alternative comforter?
An easy way to fluff up your comforter is by snapping it. Lay your comforter flat and, while holding the bottom ends of it, raise the comforter before snapping it down. The comforter will wave, creating air pockets between the feathers or fibers, effectively fluffing it. You can also separate any lumps in your comforter with your hand. Simply find any lumpy areas and massage them gently to separate the fibers in the comforter. If you have a down alternative comforter, you can put it through the dryer with tennis or dryer balls. Some dryers have a fluff setting, but if not, use the lowest dryer

r/Bedding on Reddit: Comforter Suggestions, Brands and difference between down and down alternative
August 26, 2024 -
So I just moved into my college dorm, which just so happens to be in a place that's quite hot. My older weighted blanket is good, but it is still a little stifling and as I've been using it for years at this point I want a change. I've done a fair amount of research on this subreddit, but there seems to be very few posts about the difference between down and down alternative comforters. That being said, I'd like to spend around 400~ dollars and if someone could explain which is generally better (down/down alternative), some good brands that will last awhile, and anything else in-between that y'all think I should know, that'd be great.

Benefits of down comforters- the best warmth to weight ratio, long lasting (if you buy a good one), natural materials. Cons - expensive, requires proper care and storage. Down alternatives - good warmth to weight- if you don’t need a super warm comforter, then a good down alternative maybe a better option. Cheaper than down, easy to clean and not fussy about care.

If you don't plan to keep it forever, down alternative might be your best bet. Down duvets can be quite expensive. You might want to save your $400 to invest in your forever duvet. Down alternative duvets are also easier to machine wash - down duvets are best cleaned at a dry cleaner or professional cleaners (although they shouldn't need cleaning often). Be sure to check the fill weight before buying to ensure you're getting something light. If possible, check for the term Summer Weight, Light Weight or similar. Down alternative is less breathable than down, so it can be a little hot, particularly if it is generously filled. To be honest, if your room is pretty balmy, a comforter may not even be right for you. You might consider a thin quilt.
