Key takeaways
- GOTS certification covers the whole chain - no toxic dyes and no harmful processing.
- Breathable first-touch surface with cleaner fibre integrity.
- Steam-cleanable during the Annual Care Visit without chemical agents.
The cover is the only layer in direct contact with you for eight hours a night. Purelay uses GOTS certified organic cotton for it: breathable, soft without a synthetic finish, and traceable from field to finished cover.
Certifies our organic cotton from field to finished cover - no toxic dyes, no harmful processing. The world's leading standard for organic fibres.
Most mattress covers are a polyester or synthetic microfibre knit, chosen because it is cheap, uniform and easy to print on. It also traps heat and holds moisture against the sleeper.
Organic cotton moves air and moisture instead of holding it, which is why it stays comfortable across a full night rather than warming up under you.
GOTS is the Global Organic Textile Standard, and it applies to the whole processing chain rather than the raw fibre alone.
That means the dyeing, finishing and stitching stages are covered too - so a certified cover cannot carry a chemical finish that the fibre certification alone would have missed.
