What's the difference between percale and sateen sheets?

Across the reviewers we read, percale is a plain one-over-one-under weave that feels crisp, lightweight and cool, with a matte finish that hot sleepers prefer; it does wrinkle and starts stiff before softening with washes. Sateen uses a tighter weave that feels smooth, silky and slightly warmer, with a subtle sheen. Specialist-community consensus is that percale sleeps cooler year-round while sateen feels more luxurious against the skin.
