I bought four sets of sheets, two queen and two twin, all ivory. The twin sets were as I expected. The queen sets--both of them--had a different material. The finished side is soft as it should be. The interior side on both the flat and fitted sheets is like a rough cold polyester, something you'd never want next to your skin. It feels cheap and gross. It's almost as if two different materials were fused together. I wonder if this material was only to be used for the pillowcases as the slippery side would make stuffing a pillow into them very easy, but you'd still feel the nice soft microfiber on the outside. Thankfully, Overstock is allowing me to ship these sets back on their dime. I wish these had worked out, but the feeling of the cheap side is worse that 180 thread count.
