The modular cloud sectional features cushions filled with down so that it's soft from day one. Like a down pillow, it will flatten wherever you sit. The down-blend seating is covered with a casing before the cushion covers are put on. The baffled casing prevents the fill from migrating and will help keep the fill in its place longer. The casing also helps with keeping the feathers in, which tend to migrate out when there is no casing.
