What's in our bamboo
What we test for, and what came back
1,000+substances tested
All within the limit for fabric worn against skin. They fall into the 37 groups below.
Who checks
An independent institute tests the finished fabric, and every thread and label on it, against 1,000+ substances known to harm human health. Nothing is taken on the mill's word, including ours.
OEKO-TEX® Standard 100, product class II: the tier for textiles worn against skin. Certified by TESTEX Zurich, valid to 31 January 2027. Certificate number on request.

Catalogue: OEKO-TEX® Standard 100 Testing Methods, Edition 01.2025, all 31 numbered sections.
A certificate confirms each group met its limit. It does not publish a per-substance reading, so no row claims a number it does not have. One group can cover many substances. SGS separately tested our fabric for heavy metals, formaldehyde, azo dyes and pH. All passed.
0.389W/cm²
The first-touch cool, measured. High enough to feel the second you get into bed. Five readings on our own fabric, by SGS.
What Q-max measures
How fast heat leaves your skin and moves into the fabric the moment the two meet.
Higher means heat drains faster, so it feels cooler on contact. It is the measurement behind the phrase "cool to the touch".
Why this fabric does it
Nothing is added. The cool comes from how the fabric is built, and none of it washes out.
A sateen weave, not a percaleThreads float over several others before dipping under, leaving long flat runs of yarn on the surface. More fabric touching you means heat moves away faster. Percale crosses every thread and breaks that surface up.
More contact
400 thread countHow many threads are woven into a square inch. At 400 the surface is dense and smooth rather than open and textured, so the contact has no gaps.
400 TC
Bamboo absorbs, it does not sit wetBamboo viscose pulls moisture into the fibre instead of leaving it on your skin. Damp skin is what turns warm into clammy.

Our result: SGS-CSTC report SL52615313484901TX, 3 June 2026. Average 0.389 W/cm² across five readings (0.382 to 0.397), face side, 20°C and 65% relative humidity, 20°C temperature difference. Results refer only to the sample tested.

Why these are not directly comparable. The published figures were measured at a 10°C temperature difference and ours at 20°C. Q-max rises with that difference, so the gap shown above is wider than a like-for-like test would give. They also come from different labs on different apparatus, and the published samples are knitted and plain woven fabrics rather than sateen bedding. Every result refers only to the sample tested.
Noneleft after one wash
Straight off the roll: 21 mg/kg, well under the 75 limit for bedding. After one gentle wash, none left to detect.
Why this one gets its own tab
One of the groups on the first tab, pulled out because it is the one people ask about by name.
Used to stop fabric creasing, it irritates skin, eyes and airways and causes the chemical smell some new bedding has. Traces can carry through the supply chain, so we test.
Before washingThe portion that could come off the fabric and reach your skin or the air around you.

2 of 3by-products go back in
Turning bamboo into a fibre soft enough to sleep on means dissolving the pulp and spinning it again. That takes chemicals. Here is what happens to them at our fibre producer.
At the fibre producer
Carbon disulphide: captured and reusedUsed to dissolve the pulp, then recovered from the spinning bath and sent back to the start.
Reused
Hydrogen sulphide: turned back into acidConverted into sulphuric acid, which the spinning bath runs on.
Reused
Sodium sulphate: leaves the processIt can't go back in, so it is a by-product that can be sold on for making detergents.
By-product
Why we don't call it a closed loop
That third by-product is the reason. The process isn't 100% closed, and our producer says so too. So we tell you what is reused and what isn't, rather than borrow a label that doesn't fit.
Seen in person
We visited our fibre producer and sheet millBoth, in March 2026.

This tab works differently from the other three. Those are lab results on our own fabric. This is our fibre producer's description of their process. They haven't given us recovery percentages, so we don't publish any. Dyeing and weaving happen at a different factory and aren't covered here.
How it works
How bamboo keeps you cool
It pulls heat away on contact
Our sateen weave runs long, flat threads across the surface, so more of the cool fabric touches your skin.
SGS measured it: Q-max 0.389It absorbs sweat into the fibre
Bamboo viscose soaks moisture into the fibre itself, instead of leaving it on your skin.
Holds about 11% of its weight in moistureIt stays smooth and light
400 thread count, tightly woven and silky, so it lies smooth against you without feeling heavy.

Frequently Asked Questions
How many pillowcases are in the set?
Two standard pillowcases (48×74cm) with a deep envelope fold, plus a reusable storage bag. Sheets and quilt covers are sold separately.
Will they fit my pillow?
They fit standard Australian pillows (48×74cm). The envelope fold keeps the pillow from sliding out.
Will they actually feel cooler?
The fabric is lab-tested cool to the touch (Q-max 0.389, SGS) and bamboo absorbs moisture into the fibre. If it doesn't work for you, the 90-night trial covers it.
Do they shrink?
They're pre-washed, but expect about 5% shrinkage in the first wash.
How do I wash them?
Cold or warm machine wash on a gentle cycle and line dry in the shade. Please don't tumble dry. High heat shortens the life of bamboo.
Are they OK for sensitive skin?
The fabric is OEKO-TEX® STANDARD 100 certified (class II, for fabric worn against skin). SGS found no formaldehyde after one wash, no restricted azo dyes, and heavy metals within limits.
How does the trial work?
The 90-night trial is for your first Ecoy order. Sleep on it for up to 90 nights from delivery. If it's not for you, email support@ecoy.com.au and we'll refund you in full and cover return postage. Used bedding is fine. Returned bedding is donated to not-for-profit organisations.
