The biggest issue I have sleeping is that I'm always too hot. My apartment has radiator heat controlled by our super, and even with the windows open in the dead of winter I'm always fighting to keep cool. I bought these sheets solely to help keep my body cool and they're incredibly effective. I was surprised at the quality for the price- they seams and edges are well trimmed, the stitching tight, and the fabric is a solid weight. I don't like sheets that are too slippery but these strike a perfect balance: not too buttery soft, not too cotton rough.
