Frequently Asked Questions

Sateen uses a four-over-one-under weave structure that brings more yarn to the fabric surface than percale. The result is a smooth, slightly lustrous finish with a softer, heavier drape. At 300 thread count, this sits between lightweight summer percale and heavier winter flannel, suitable year-round. It improves in softness with every wash.
GOTS (Global Organic Textile Standard) is the leading international certification for organic textiles. It covers the full supply chain, fibre sourcing, spinning, weaving, and manufacturing. The cotton is grown without synthetic pesticides or fertilisers, and every processing stage meets strict chemical and labour standards. No harmful dyes, heavy metals, or chemical finishes are permitted under GOTS.
Cottsbury duvet covers are sized to standard UK dimensions. A Single (135 x 200 cm) fits a standard single duvet. A Double (200 x 200 cm) fits a standard double. The King (230 x 220 cm) fits a standard UK king duvet without overhang. Size up for deep-fill or continental duvets.
Machine wash at 30 degrees on a gentle cycle with a plant-based detergent. Avoid bleach. Line dry where possible. The coconut-shell buttons stay more durable at lower temperatures. Do not iron the buttons directly.
