Williams Sonoma Goose Down Duvet Insert

Fill power measures the loft and insulating ability of the down clusters. A 700-fill-power rating indicates high-quality, larger clusters that trap more air, providing superior warmth and fluffiness without adding excessive weight to your bed.

No, the duvet is constructed with box quilting, a design that sews the fabric in a grid pattern to create individual pockets. This keeps the down evenly distributed across the entire insert, preventing cold spots and lumping.

Yes, the down undergoes a rigorous hypoallergenic cleaning process to remove dust and allergens. Additionally, the high-quality cotton shell acts as a barrier, making it a safe choice for most sensitive sleepers.

This insert features corner loops designed to secure it to the ties found inside most standard duvet covers. This ensures the insert stays perfectly aligned and centered within your cover throughout the night.

Yes, this duvet is machine-washable. We recommend using a large-capacity washer and following the care instructions on the label to maintain the integrity of the down clusters and the cotton shell.

These certifications ensure that the down is sourced ethically and that the entire product has been tested for harmful substances. It guarantees both animal welfare standards and that the materials are safe for human health.
