What makes this featherbed different? For that extra layer of sink-in softness, our Featherbed is our most plush mattress topper, offering over 4” of cloud-like cover. It’s made with cruelty-free, RDS-certified fills in a dual-chamber design: the top layer is filled with 550 fill power white down for ultimate comfort, while the separate bottom chamber is filled with feathers for generous support. The unique baffle box construction keeps the fill perfectly in place to maintain fluff and shape over time, all wrapped with a soft, breathable fabric shell. The Feel Supremely Plush – Dual-chambered in feather and down for superior loft and sink-in softness
