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

A solid Dark Slate bedding set on a 300 thread count, 100% GOTS Certified Organic Cotton sateen base. Dark Slate is the deepest colourway in the Cottsbury Classic range — a dark, cool charcoal-grey that reads almost black in low light and reveals its grey undertone in natural daylight. On a sateen weave, which brings more yarn to the surface than a plain or percale weave, the dark colour sits with a subtle sheen and a weighted, full drape. 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. The King (230 x 220 cm) fits a standard king without overhang. Size up for deep-fill or continental duvets. The fitted sheet suits mattresses up to 30 cm deep.
