White Optical Check Organic Cotton Sateen Weave Bedding Set — 300 Thread Count, 100% GOTS Certified

An all-white bedding set in which the check pattern is created entirely within the weave — no dye, no print, no colour contrast. An optical check (also called a self-check or damask check) uses alternating sections of sateen and plain weave at right angles to produce a pattern visible only through the way different weave structures reflect light differently. The result is a tonal, tone-on-white geometric grid that is subtle in daylight and more defined under directional light. It is the only patterned design in the Cottsbury bedding range that introduces visual texture without any added colour. 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

The optical check is woven into the fabric during production using a variation in the weave structure rather than a printed or dyed pattern. The result is a tonal, white-on-white effect that is subtle in ambient light and more visible at close range or in direct light. Because it is woven in, the pattern does not fade or wash out over time.
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.
