Materials
Quiet by design. The detail behind the bedding — how it's made, how to care for it, and how to reach us.
MATERIALS
What we use.
What we never will.
We name every fiber. We name every certification. No vague promises — just what it is, where it comes from, and what it's made of.
LYOCELL CLOUD & PREMIUM LYOCELL CLOUD
100% Lyocell
Eucalyptus pulp, dissolved and spun into fiber. Produced in a closed-loop process that recovers and reuses over 99% of the solvent. Nothing wasted.
The fiber surface is naturally smooth. The weave breathes. Moisture moves through the fiber core rather than sitting on the surface — an inherent property of the lyocell structure, not a chemical finish.
OEKO-TEX Standard 100 certified. No synthetic coatings. No PFAS. Nothing petroleum-based.

BAMBOO FROST
100% Bamboo Viscose
Bamboo pulp, woven into a fabric with a cool, silky hand-feel. Naturally smooth against bare skin, with a subtle luster and fluid drape.
Bamboo is one of the fastest-growing plants on earth — no pesticides, no irrigation. The fiber is spun from the pulp, not coated or blended. No PFAS. No synthetic finishes.
100% Bamboo Viscose Smooth fiber surface Breathable PFAS-free Biodegradable
LINEN BREEZE
Cotton & Linen
90% cotton, 10% linen. The cotton provides softness. The linen adds a dry, textured hand-feel and natural structure that relaxes with every wash.
Linen is one of the oldest textile fibers — strong, absorbent, and long-lasting. Blended with cotton, it keeps its character while staying approachable from the first use.

PROOF, NOT ADJECTIVES
OEKO-TEX Standard 100
Independently tested for over 100 harmful substances — including heavy metals, pesticides, phthalates, and formaldehyde. The certification covers the finished product, not just the raw fiber.
All material properties described on this page refer to the inherent characteristics of the fibers themselves, not to specific health outcomes. Certification details are verifiable through the respective issuing bodies.
Questions
A few things to know.
Orders placed before 4pm ship the same business day. Delivery takes 2–4 business days, free on every order. Everything arrives plastic-free — a paper box and a cotton bag.
Sleep on it for 30 nights. If it doesn't sleep cooler and calmer than the plastic you had, send it back — free returns, full refund. Washed bedding included.
Machine wash cool on a gentle cycle and skip the softener — lyocell softens on its own, wash after wash. Line dry or tumble low. No ironing needed.
A silk-soft fibre spun from FSC-certified eucalyptus in a closed loop that recovers about 99% of its solvent. It wicks roughly 50% more moisture than cotton, so it sleeps cool and dry. OEKO-TEX® 100 certified, plastic-free to the packaging.
