While sateen sheets are similar to satin sheets, they aren’t to be confused with one another. The satin weave structure (one under, three over) creates sateen sheets, but yarn is used rather than filament fibers. Despite the differences in material, sateen sheets are just as elegant and silky smooth as satin. They are less durable than percale sheets but also better for cold sleepers and cooler weather. 

 For those who like a balance between two extremes, a medium-weight duvet insert is the perfect choice.  Medium Weight Duvet Insert provides a moderate level of warmth, making it suitable for year-round use in many climates.  The mid-weight down comforter core provides enough warmth to keep you cozy without feeling too heavy or light.
