I purchased one in king/sage for myself and f/q/navy for my teenage son. They both fit perfectly, no slipping out of the corners and the fabric and color is extremely luxurious. They also wash up beautifully, are virtually wrinkle free and smooth and silky to the touch. I would highly recommend this product to anyone looking for a high quality duvet cover. I shopped around at other bed and bath stores for the same quality and price and didn't find any that came close. I love Overstock and am a frequent buyer!
