FAQs

Our bed linen is made from 100% extra-long staple cotton (600 TC, sateen weave) and 100% high-quality mulberry silk (22 Momme, Grade 6A). Certified according to OEKO-TEX® Standard 100.

Thread count (600 TC) alone does not determine quality. The fiber length and special weave are crucial. The extraordinary construction of the fabric results in a smooth surface and a soft feel. At the same time, it impresses with high durability.

Designed in Germany and responsibly manufactured in India in our selected, certified production facility.

We work exclusively with partners who share our values: the use of the finest natural raw materials, transparent and sustainable production, and a respectful approach to people and the environment. Our partner companies primarily employ women under exemplary working conditions, promoting education and social stability in their communities.

Yes. The cotton gets softer with every wash while retaining its shape.

Cotton and silk naturally regulate temperature – they have a cooling effect in summer and are pleasantly warming in winter, all while remaining breathable for a restful sleep.

All duvet and pillow covers have a subtle, concealed, high-quality zipper. Our Hospitality Collection (400 TC) features a hotel closure.

The UN TERZO silk pillowcase promotes restful sleep and is especially gentle on skin and hair. The particularly smooth surface reduces friction and can thus prevent hair breakage and frizz as well as improve the complexion – for a fresh, well-groomed appearance in the morning.

In contrast to other textiles, silk draws less moisture from the skin and hair and helps to preserve natural hydration – for visibly well-groomed skin and supple, shiny hair. At the same time, it supports the effectiveness of your skincare, as creams and serums are absorbed less by the fabric and remain where they should work: on your skin.

Thanks to its natural breathability and temperature-regulating properties, silk feels cool in summer and pleasantly warm in winter. It is also hypoallergenic and therefore particularly suitable for sensitive skin.

Our exclusive UN TERZO 600 Cotton Silk Pillowcase combines the highest quality mulberry silk (22 momme, Grade 6A) with extra-long staple cotton (600 TC, sateen weave) in perfect harmony – with silk on one side and cotton on the other.

This special pillowcase was designed to ideally complement our UN TERZO 600 Cotton Collection and enrich your evening routine with luxury and exceptional comfort.
