I carefully selected these sheets based on the reviews. The bottom sheet construction is unlike any I have seen. It has additional fabric serged onto the body of the sheet along with an extra wide elastic band. The sheet fit well over my plush euro-top mattress with lots of room to spare. The pillow cases fit just right on my goose down pillows. not too loose or too tight. The top sheet should be about 6 inches longer to accommodate the thicker mattresses, but nonetheless, it just fit and I will make do. The fabric is great. Light to medium weight - perfect for Arizona. The finish of the fabric is almost sateen, but not really. I hope that this review is helpful to others. I've read a few angry and outrageous reviews here.
