Feather & Loom White Goose Down & Feather Dual Chamber Mattress Topper review

Feather & Loom's topper is Costco's down option. It has two chambers: white goose down on top for loft and goose feather underneath for medium support, inside a 500 thread count cotton dobby cover with a 3-inch gusset. It is overfilled, rated at 600 fill power and certified for responsible down sourcing, and a waterproof barrier sits inside. Costco listed the queen at $114.99 on November 11, 2026. Two limits stand out. The dual-chamber stretch skirt fits only mattresses from 18 to 21 inches deep, so it suits thick pillowtop and hybrid beds and will be loose on thinner ones. And the listing offers Queen, King and Cal King only. Down and feather toppers also shift and need shaking out, which is why it scores lower on ease of use. Its 542 reviews averaged 4.0 out of 5 on the queen listing.
