Thanks for the explanation! TBH it sounds like something that I would hate and find a bunch of extra work, but I can see why other people would like it and find it useful.

WE DIDN'T WANT TO KNOW!

I have a king sized bed, and bought a new comforter for it in December. It's nice, with fleece side and a smoother side, and a kind of fiber fill. Only problem is that I recently realized it doesn't come close to fitting in my wash machine, so I'll have to take it to a laundromat. Do you think a duvet cover would work over something like that, even though it doesn't have any ties?

To me having a house always set to the same temp sounds like the fancy concept. Do you live somewhere very warm? In winter we only heat the house during the day and I've woken up in a 14°C bedroom. Thick duvets are a must.

I sleep best when I'm cold so I try to keep my house cold (summer months I just deal) and instead of a single warm cover on my bed I have multiple throw blankets. It's not aesthetically pleasing but then I can cover up with as many blankets as my body wants and I can also layer where I'm cold. Some nights I have 5 blankets over my upper body and head and my legs are completely uncovered and sometimes my feet are freezing and the rest of me is fine.

For the first three decades of my life my duvet had the loops but the cover didn’t have the ties. I just thought the loops were something to grab on to while spelunking into the cover to insert the duvet 😂

Same, and I even buy my duvets from IKEA ...

Our comforter is tied to the bed footrest on my husband's side, because otherwise I steal it in my sleep. It keeps marital harmony!

I dont know about the previous commenter's fancy duvets/covers but the ikea ones have switched between snaps and loops and none at all between product lines. I have noticed though that the cotton covers tend to stick well to the polyester duvets such that they stay in place without

Duvet inserts usually have a loop on each of the corners for the ties on the cover to tie on.

As another post said the corners have a loop for the tie. Even without those loops I’ve tied the cover around a section of the duvet corner without issue. My cover is linen, so maybe other materials don’t work as well? YMMV.

Look for duvet magnetic clips. Amazon has a lot of varieties, and if you don't support Amazon it gives you an idea of what to look for.

You know, I always thought "Duvet Cover" was just a fancy word for that blanket that goes on top of normal blanket in hotel rooms and never gets washed. But after watching this video, I now realize it's something completely different that I'm too poor to comprehend.

Never seen a blanket with strings hanging from it that can be turned inside out... What's it used for?

Holy shit

Even cheap Amazon and ikea ones have them I don’t know how you managed to buy tie-less duvets

This gives a good idea what it typically looks like if your duvet and cover has it.

Sometimes (but not always) there are little straps in the corners of each to tie them into place. If you’re ever buying another it’s worth looking for that!

So at one point I needed these for a king size fitted sheet that would not stay comfortable, I knew they existed but didn't know what they were called. What do I look up that gets me exactly what I wanted? Bed suspenders....

Mine has no straps. I just use big safety pins.

I have special duvet pins. They're like the anti theft tag pins on the clothes at stores but smaller. The pins themselves have ridges along them that get caught by the counterpart. You have to press a tiny button in to release it, but that button is tucked underneath the head of the "receiving" side so it's not really possible to press it accidentally while tossing around in the bed.

I bought a pair for dirt cheap. One of the best dollar store purchases of my life honestly.

Mine does. They work alright, but the duvet still slips a bit.
