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

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!

July 10, 2024 -

rn I have a bedsure lightweight duvet insert, polyester shell and filling. I tried a silk filled duvet to see if I would like it better and I absolutely hated how it clung to my body, so I now realize that down alternative is my fill of choice. I'm considering a new comforter because 1. I have a full size but think a queen duvet might look a little better and 2. I'm wondering if some comforters might sleep a little cooler without having zero loft. But I've been comparing all sorts of brands in the <$200 range and wondering if there's even a major difference or if I should just save my money on a nicer cover?

ETA: right now the options I'm looking at are quince premium down alternative, pottery barn recycled down alternative, or just keeping an eye out at homegoods/tj maxx etc for a deal on something with a cotton shell. I was also looking at saatva's down alternative, but that would be a bit of a splurge for me and I wanna make sure I can return it if I'm not happy with it... am also open to real down but a little conflicted about it as a vegetarian (more sustainable though) and also a little apprehensive when I read about people saying they get feathers and dust everywhere

In terms of sleeping cooler while still maintaining fluffiness, it's a tough one. Down alternative (synthetic) is just not as breathable as natural fills. Opting for something with a cotton shell will help marginally, as cotton is more breathable than polyester. At some point, you may need to choose between fluffiness / weight and warmth and see which one you're willing to compromise on more. When shopping across brands, I would compare specs such as shell type, shell thread count (higher TC = softer), fill type (microfiber, polyester batting, or other?), fill weight, etc. You should be able to get something good quality within your budget, it's just about finding the specs that work best for your needs. Also worth checking if the brand offers a good return policy and/or warranty so you don't have to stress too much pre-purchase. In terms of natural down, it's a tough call. Down is a by-product of the meat industry, and you can find many companies that source their down ethically and post-mortem, with certifications against things like force-feeding, overcrowding, lack of vet care and other inhumane practices. But if you are opposed to eating meat and the meat industry period, these assurances may not go far enough for you, and that's ok. You're right to consider sustainability - not only is down a natural product, it should last you a lifetime (or longer) and can help reduce home heating costs in a cool climate. In terms of your concern about leakage, make sure that the company is using down-proof cotton and that they offer a warranty in case of any defects. There shouldn't be a lot of dust coming out, ever (given proper care instructions have been followed). Commercial down is only allowed to have a minimal amount of dust in it. It's impossible to remove every bit, but the threshold is quite low. Make sure to purchase from a reputable company that has processes in place to test their down regularly for cleanliness.

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.

I've been using down duvet inserts for awhile, and I really hate the feathers that leak out and the shifting. These are box stiched duvets that I've had and after awhile all the down feathers go to the edge with the middle being nothing but cloth. And since they are box stiched all the fluffing i try to do cannot get the middle filled up again. I also hate the feather dust that flies around everywhere when i take it out of the cover.

So i'm thinking of down alternatives which are hypoallergenic and some are even temperature regulating. Does down alternative stay fluffy better? Or will have the same problem?

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!!

I’m search of a great, FLUFFY comforter for cold winters. Mine (which was $200 on sale) lasted two years before the filling started moving around. Tennis balls in the dryer and fluffing it myself didn’t work. The entire area that I usually sleep under on my side of the bed has completely lost it’s filling. (See photo- with the light shining above it, you can see the left side has lost it’s filling compared to areas around it). I realize it may happened a little, but this is ridiculous. Need a fluffy, warm comforter that won’t do that.

Just out of curiosity, what was the brand? Most down comforters are supposed to keep the down fill in the boxes for a lot longer than just 2 years. It would be good info so people can avoid that brand in the future, honestly. On down you'll more than likely get a lot of recommendations from users on here (from Costco to St Geneve), but if you want ultimate fluffiness and warmth in winter usually the best thing to do is get a duvet cover and pack in two oversized down comforters that are either summer weight or all-season weight. You'll have such a fluffy bed you won't know what to do with yourself, lol ;) Personally I'd just get two summer weights or a summer weight + an all-season weight for much colder temps. More than that and you might overheat if your temps aren't below 50F in your room. If you're looking for cheap deals, I think you'll find a lot of them on ebay in terms of down, but a decent brand that's got some cheap prices on ebay is DaniaDown. There is a seller that sells a few of the down comforters from them at a pretty decent price for what you get that might interest you; most Canadian down brands are pretty decent quality, I've found, but if you'd rather stick with the more highly-regarded brands like St Geneve or Scandia Home, that's fine too! Polish down is usually considered the best down in the world after Eiderdown, but when you get into expensive down you start getting prices that are crazy-high. If you're happy with duck or European goose down at the most then you can probably find much cheaper deals, overall.

Mae sure you buy a comforter with a Baffle Box Design apposed to standard sewn through. Similar to a gusset on a pillow, a baffle box is an internal fabric wall that not only prevents the fill from shifting throughout the night (keeping it evenly distributed), but allows the fill to reach its full loft. A baffle-box design allows the fill to expand to give you a cloud-like comfort. Other things to consider is the fill power and also if its actually real down. I believe down only needs to be 75% to be considered down. The rest is feather junk which has no loft. I have an Eli & Elm and love it!

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?

Comforter or duvet insert (they're pretty much the same).

Say you don't wanna use any animal products like down (poor geese being plucked alive).

In my opinion, based on my own a couple of hours research, I've narrowed it down to either Eucalyptus, and/or microfiber.

There's also silk, but I read that it traps heat a lot, so probably not gonna go with that.

Microfiber, mainly because I'm intrigued with Snowe Down Alternative comforter. But microfiber itself is pretty much plastic? So, that's kinda meh.

Eucalyptus is probably from Buffy (though I feel like it's because they spend a lot on marketing, so their company comes up a lot). There's also Sheets & Giggles eucalyptus comforter. Unsure between the two.

Between eucalyptus and microfiber, I don't even know the pros and cons other than microfiber is plastic while eucalyptus is plants. Other than that, I don't know which one performs better and/or more durable.

So, what do you think would be best?

Hey hey 👋 Colin here, founder & CEO of Sheets & Giggles. Going to do my best to not be salesy here and not advertise, very much against my natural instincts. Just want to participate and weigh in if it's helpful. Similar to how people call viscose "bamboo," "eucalyptus" is the current consumer vernacular for another type of cellulosic rayon called lyocell, which both S&G and Buffy use for our sheets and comforters and other products. Lyocell is softer than cotton (lower coefficient of friction), better for hot sleepers and people with sensitive skin, and just all-around amazing. Certified vegan and cruelty-free as well, hypoallergenic, effectively zero waste during production, and considered very sustainable. Basically, microfiber is polyester (plastic). If it's recycled poly from actual discarded bottles (not water bottles made specifically to be turned into "recycled" poly, as can be the practice in China), it's actually doing something productive by taking those bottles out of the environment. S&G's comforter has a 50-50 lyocell / recycled poly filling, so it's fairly environmentally friendly in this regard (both the lyocell and the true recycled poly). If microfiber / polyester isn't recycled, I'd definitely avoid it to avoid putting new plastic into the world. Microfiber / poly traps heat and is known for sleeping hot, so avoid anything that's 100% poly, especially in the summer. A mix of fabrics can be good for all-seasons comfort vs going too much to one extreme or the other on temperature regulation. The best advice I can give you is to compare reviews across channels (i.e., see what a company's' website, Facebook, and Amazon reviews say and if they match up). If they don't match up and the website is considerably higher scored, it's likely because there's some hiding of reviews going on on their .com (which often will get mentioned in reviews on Facebook and Amazon, "I couldn't leave a review on their site"), which for me as a consumer is a red flag. If they don't allow native Facebook reviews on Facebook (cough Brooklinen) and just hook into their site reviews, that's also a huge red flag because companies can't control the visibility of FB or Amazon reviews, so those are important for confidence. On return polices and stuff, most companies are fairly similar and consumer friendly these days, but S&G also has no time limit on our return policy. Which I'm sure won't hurt us in the long run... oh god. And I can indeed confirm that Buffy spends wayyy more $$$ on advertising than we do, but S&G is the only bedding company with an unfocused CEO who spends too much time on reddit on Friday afternoons. And you can take that to the bank. Anyway, whatever you choose, hope you love it! Top-tier quality bedding is life-changing. (And because you're someone who found us in the wild, I'd appreciate any feedback or Q's you might have about S&G, we love hearing from people new to our brand. Feel free to DM me as well.) Cheers, Colin at S&G

I’ve searched tons of threads and was looking at Costco’s Downlite hotel & resort Hungarian white goose comforter, but it seems too light for her. She’s perpetually cold and I want super fluffy and less flat. Then I found Feathered Friends’ Bavarian 700, but it’s out of stock 😭 I don’t feel like Ikea or Amazon brands would be top-tier quality? I’d prefer not to spend more than $500 for a king but will spend up to $1k if it’s worth it.

Is it better to stuff two duvets in one cover, and if so, anyone have good experience with this method with specific brands? I just want her to be comfy for the winter and years beyond. She just had several uncomfortable surgeries.

Last question, are down alternatives as comfy as down comforters themselves? She won’t care what’s in it if it’s gloriously comfortable.

Please help me out if you can, any suggestions and firsthand experiences are greatly appreciated 🙏🏼 I’m definitely not a bedding aficionado

The issue with IKEA duvets is they use non standard measurements, so you're stuck with their duvet covers. I had one in my Queen and it never covered the bed quite right. They're minimal warmth comforter is great for someone who wants the weight of a comforter without retaining heat, it's one of the few polyester things I think does its job well, but I wish it fit my bed.

I’ve had one for about ten years, and it’s been okay. I’m planning to replace it this fall. It’s light weight, so good in summer, but needs extra blankets in the colder months. Down alternative is definitely better on the low budget end. Buying cheap down is just buying trouble (mostly feather, odor, clumping), and quality down is expensive. Im not convinced it’s worth it for most people for a comforter/duvet. Quality down pillows are worth it though. There are many down alternatives that are generic polyester fill. And there are a few that have a reputation for excellence while still not too expensive. I have a sleeping bag made with Primaloft, and it’s the real deal. It’s twenty years old and still in great condition. That’s what I’ll probably buy. Here’s one that you might like. This company has a great reputation and sells several different down alternative comforters. I’ve been meaning to call them and get more info on their various options. They are big suppliers to the hotel industry. So I’d recommend Primaloft without hesitation, and then you have to get the right weight for your preference.

Couple months ago I bought a very expensive down comforter and cover from the company store as this subreddit has rarely steered me wrong.

While I will say that the down comforters are obviously very high quality, I did not like it and hoped to grow into it. I have not. It's very baggy/crinkly, always making sounds when move even though it's been thoroughly used and even washed at this point.

Im looking for something that doesn't gather static, and is nice and smooth on the skin. I don't sleep cold or hot so that doesn't matter. Any ideas on what I should be looking for?

I am redoing our bedding. We’ve had a paper thin duvet insert for years and it works okay but doesn’t give us the kind of plush, lofty feel. We are also hot sleepers but still want warmth throughout the year.

I’ve done a ton of research lately on the difference between down vs down alternatives, types of sheets for hot sleepers, etc. I’ve learned silk inserts are the best but that’s out of my price range atm (saving for a wedding)!

I ended up purchasing a king Nestwell Down Comforter in Medium Warm from Marshall’s with a queen Threshold (50% cotton/50% recycled polyester) duvet cover. But after night 1 = HOT LOL. Is it the insert or is it duvet cover? Do we need cooling sheets? I ran back to Marshalls and bought:
