For easier duvet cover changing, I’ve just ordered some of these.

I also use “coverless duvets” from the Fine Bedding Company. They are just a bit more expensive than ordinary duvets but you don’t need duvet covers so you save money. They are very lightweight so perfect for summer - we are currently using a 4.5 tog but they do winter ones too.
No changing covers as you just put the entire quilt in the washing machine and dry outside if possible or half an hour in the tumble dryer. Very hygienic because you are washing all of it.

Would a king, or super king size go in an ordinary washing machine, though? I mean, not just as in being able to be stuffed in, but able to be washed without the machine deciding it didn’t like it?

I usually turn my duet cover inside out, then put my hands down the inside to grab the two bottom corners. I then grab two corners of the duvet and with a bit of wriggling, I get the cover to move down so that my hands are now on the outside, I then start to shake the whole thing until the cover reaches the bottom. A bit difficult to explain but it works a treat.

Ditto Stephanie48 , mine is also Kingsized - I do it it myself ( at 76 ) tho I don’t relish it and probably don’t change it as often as it should be changed - but at my age living alone it doesn’t get too ‘used’ !

lol. I am 5 feet tall quite old and quite fat with a super king size duvet but have never had any problems and don't use any other devices etc. When I visit friends or family members some of them ask if I would mind changing their duvet cover as it honestly takes me less than 5 minutes to remove one and replace it. I think the key is to make sure the cover is a perfect fit for the duvet, and that if it is rectangular that you insert the duvet the correct way ie short /long edges matching . I lay the cover on the bed, right side up, and right side out, with the top at the headboard end and make sure I have the quilt the right way around. I grab tight on to the two top corners of the duvet with my left hand and put it all inside the cover heading for the top middle, still holding tight. . At the same time with my right hand I get into the top right corner of the cover. I then place the right corner of the duvet in there and leave it, whilst I then place the top left corner of the duvet into the top left corner of the cover. I then move to the foot of the cover where the buttons/studs usually are, and providing the duvet isn't twisted, simply place the two bottom corners of the duvet as far as possible into the two corresponding corners of the cover, grab these two bottom corners on the outside through all layers of duvet and cover and then shake as hard as you can to spread the duvet evenly within the cover. You shouldn't need more than 2 big shakes. Then button/stud the cover. I appreciate that not everyone has the strength to do this. If you aren't able to do big shakes then its ok either do smaller shakes or a few smoothing out actions with your hands. No full day windmills necessary ( that sounds suspiciously like an excuse to lay about on top of bed all day tbh ) , or pegs, clips, contortions, etc. And def no husband involved it would be complete carnage. Its taken me longer to type this than it would to change it, honestly. good luck to you all though !

I try and use two handy gadgets called grandsons, if I can.
They have big long arms and are tall enough to wave the quilt into place.

My lottery win treat would be fresh bedding daily with the luxury of paying someone to do the task and launder of course.
As the odds are against this happening maybe I too should
invest in some clips.

Baggytrazzas exactly the way I do it.

The problem could be solved with these covers. How simple is this solution?

They just need a bigger range of colours and I might be tempted.

Don't use duvets in summer, far too hot, linen sheet and cotton blanket!
