I received this for free in place of my honest opinion. The sheet is very smooth, actually. It's thin and light, which I like. I'm a hot sleeper, so I like thin sheets. I'm not sure about how durable it is yet. But so far, so good. It is made out of polyester, so it's made out of plastic. Don't say I care for that. When things are made out of plastic, they're made out of bad chemicals.
