Producing natural-filled pillows or duvets may have many issues, including the sourcing of feathers and down. That is why the best bedding suppliers only work with partners who share the same ethical values. We want the benefits of bedding to extend beyond a good night's sleep. All our sustainable goose down and feather bedding are responsibly sourced and independently audited for compliance. Our suppliers are also monitored to ensure they practice the highest standards of production. Our ethically sourced goose down duvets and pillows are also certified by Downpass and RDS, making them products with ethical value. You can check the authenticity of the certificationlink.
