Dimensions: Down and feather-filled products are packaged tightly during shipping. Upon receipt, remove this item from its packaging, fluff gently, and allow several hours for full loft recovery. In addition, products sealed in plastic packaging sometimes have a disagreeable scent because of concentrated natural fibers. A few hours of airing typically removes the odor. We recommend that this item is fluffed at least once a week to maintain down distribution. The digital images we display have the most accurate color possible. However, due to differences in computer monitors, we cannot be responsible for variations in color between the actual product and your screen.
