White King Duvet Insert, 90 x 102 Inch Comforter for Covers

A white duvet insert sized for a king bed, made to slip inside a duvet cover or to serve as a plain comforter on its own. It is the foundation layer for a bed that changes with the seasons, since covers can be swapped while the insert stays.

The insert measures 90 by 102 inches in a king size. Its white finish will not show through lighter duvet covers, and it works with any cover in the same size.
