Navy Classic Organic Cotton Sateen Weave Bedding Set — 300 Thread Count, 100% GOTS Certified

A solid Navy bedding set on a 300 thread count, 100% GOTS Certified Organic Cotton sateen base. Navy is the deepest blue colourway in the Cottsbury Classic range — a rich, dark blue with minimal grey or green undertone that reads as saturated and traditional in most lighting conditions. On a sateen weave, the depth of the navy dye sits with a restrained sheen that gives the fabric more surface interest than the same colour would have in a flat percale weave. It is the boldest solid colour in the blue family within the Classic collection. Closure is concealed coconut shell buttons — no plastic, no metal.

Rated 4.8/5 by over 1,500 customers. Available in Single, Double and King.

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.
Yes. The 300 thread count sateen weave produces a smooth, low-friction surface, and GOTS certification ensures no harmful chemical residues from processing. Organic cotton is widely recommended for people with eczema, dermatitis, or general skin sensitivities.
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.
