thank you
a good reminder that the 'professionals' are often no better than some non-professionals.

I am glad I taught about Koko the talking gorilla today. Did some messy art and ate jambon cru for dinner, out of the plastic cover.
Our duvet is the same size, also Ikea one.
I use the same technique and it's not difficult, except for the weight of such a big duvet. I prefer to let my OH do it, simply because he's physically stronger when it comes to shake it to place
I change the kids' duvet weekly in less than a minute though, 90x200.
Thats my take on the subject.
You simply turn the covers inside out when taking them off (for me actually the easiest way to take them off). That's how they go thru the whole process including when folded and stacked in the wardrobe.
This may no longer be valid (if it ever was to begin with) but the logic behind it all was to protect the colors. I was told (in the good old days) that washing and drying (especially tumbler'ing) wears the colors so turning the covers inside out was considered good practice. I wouldn't claim though that this still applies today, not to a noticeable extent.
An additional benefit is that if you drop the cloth and get a minor stain or two they will be hidden once reverted. This may be irrelevant in a private home with colorful cover surfaces but in a professional environment the situation may well be different. I'd think in hospitals the slightly improved hygiene is the most important aspect, the (invisible) stains on the white fabric the most important in the hospitality industry.
If one were to ask someone working in a professional laundry they might add additional reasons in the sense that the machinery has been set up to produce inverted covers.
Best place I ever had for putting on double duvet covers was in a house in England, where, using the 'inside out, hold onto to corners and shake the duvet into the cover' principle, I did it hanging the whole thing over the railing of the upstairs landing. Brilliant and very quick.
