There really is no better fill. A cushion cover is only as good as what's inside it. Choose the wrong insert and even the most considered cover collapses - literally. Choose the right one, and suddenly the whole thing comes together: full, structured, settled. Our square feather cushion inserts are filled with responsibly sourced, certified humane down. They have that particular quality that natural materials carry - a loft, a weight, a way of sitting in a cover that synthetic fills spend a lot of energy trying to approximate. These don't need to try. Available in four square sizes to match the most common cushion cover dimensions: • 45×45 cm - armchairs, reading corners, van benches, kids' rooms • 55×55 cm - the classic. Sofas, beds, main living spaces • 60×60 cm - statement pieces, floor use, large sofas • 90×90 cm - oversized floor cushions and feature moments Each insert is biodegradable. When it eventually reaches the end of a long life, it goes back to the earth — not a landfill. What to know • Certified humane product — responsibly sourced down • Biodegradable fill • Natural loft that holds its shape with minimal care • Size up by 5 cm from your cover size for an extra-plump look • Spot clean or dry clean; keep dry and give them an occasional shake • Not suitable for feather allergies - see our polyester inserts instead Sizing guide Match the insert size to your cover size for a clean, full result. Prefer a plumper look? Go one size up - a 60×60 cm insert inside a 55×55 cm cover gives a generous, cloud-like finish. Never go smaller than the cover: undersized inserts make covers look flat and underfilled. Pair with Browse our full range available in 45×45, 55×55, 60×60, and beyond. From the canvas Highlander to the overdyed Wanderful series, each cover is designed to be lived in. Pair your insert and cover together and save.
