The sheets are indeed very soft and smooth, and generously cut to fit a thick mattress. They were advertised as cotton and polyester; the 45% polyester content is microfiber. The pillowcases have a wide hem on one side (as shown in the pictures) but the other side is a fold-over design, not a standard hem. I'm pleased with the colour, the dimensions and the easy-care aspects of this sheet set, but downgraded the rating because they feel somewhat flimsy and because the hemming on the pillowcases makes them look and feel cheap.
