Heirloom indoor cushions are filled with full feather inserts made in Australia from post consumer, duck feather. Feather inserts are a natural alternative to foam inserts.(
Polyurethane foam inserts are a product of the petroleum industry and are not considered an eco-friendly product because they are made from a nonrenewable resource).
Feather inserts do require a 'fluff-up' each week but are much longer lasting to general foam inserts which remain flattened after a period of use.
