The cushion covers can be purchased with or without a cushion pad. If you prefer it filled, you can choose between British sheep's wool or fibre. They’re both eco-friendly and oh-so-comfy! • British sheep's wool with cotton casing: handmade, eco-friendly and sustainable. It's also anti-allergy and naturally fire retardant. • Fibre with corvin casing: made from recycled plastic bottles and environmentally friendly. I don't offer feather fillers as I can’t make sure the duckies had a lovely happy life. If using your own, I recommend a 48cm to 50cm pad for a lush plump fit. Please note: Cushion pads are only available for UK delivery.
