On Eastern King bed, sufficient width, overhang on sides, such that two side sleepers have plenty of coverage; extra length allows folding over around 8-12" for extra warmth and softness over shoulders. Perfect for fall and spring; add cotton and/or fleece blanket underneath colder weather. Soft outer fabric with self-binding, less likely to show wear than satin trim. Lightweight but plenty of warmth of Primaloft fill. No worries about fill shifting since 6" boxes are sewn through. Haven't washed yet, but will require commercial size washer and dryer with dryer balls -- such is the hassle of King size.
