I'm reading these absurd reviews, and wondering what part of the headline is confusing? It's a COVER, NOT a duvet. It's COVERS your duvet, like a pillowcase covers a pillow. Reading is fundamental! ("Two sheets sewn together"? "Not very warm"? What do you think a duvet cover is?)
Ok, I ordered this based on the picture. My only complaint is that the color grey isn't grey at all, but a greyish brown. Grey is black mixed with white; this has tones of red in it. Other than that, (I can live with it) I found this to be of high quality, especially for the price. The fabric, while being synthetic, feels less like poly and more like cotton. It fits OVER MY DUVET perfectly, (see what I said there?) and the pillow shams fit just right. Haven't laundered it yet, but I don't anticipate any issues. Would recommend.
