Our top-of-the-line cushions are Feathers and Down. The seat consists of the same Polyurethane foam core used in Soft-Fill cushions, but is surrounded by a channeled envelope of 90% feathers and 10% down. The cover is made of cotton, down proof ticking. Feathers and Down back cushions are channeled into cotton envelopes to prevent shifting and clumping. Feathers and down are pre-washed and air-blown at our factory to reduce dander. Even though this mixture requires a bit more fluffing, the luxury and comfort are unsurpassed.
