Is this really plastic-free? Yes — and here's why

Polyester and poly-blend sheets are made of plastic, and they shed synthetic microfibers you breathe in all night. These sheets are 100% GOTS-certified organic cotton — a natural plant fiber with no plastic in it to shed.

What to avoid instead

Polyester and poly-blend sheets are one of the biggest — and most overlooked — sources of microplastic exposure in your home. You spend 8 hours a night with your face pressed against them, breathing in fibers.

Research finding

Research shows synthetic textiles are the #1 source of microplastic fibers in the home environment. Polyester sheets shed thousands of microscopic plastic fibers with every use and wash — fibers that become airborne and enter your lungs while you sleep.

How we verify — and what we don't

Straight answer: we're a research team, not a testing lab. Here's exactly what our rating is based on — and what it isn't — so you can weigh it honestly.

What we check

What the product is made of, from the maker's own specs and product listing.
Whether any part that touches you or your food uses PTFE, PFAS, plastic, or a coating that can degrade.
Peer-reviewed research on how that material behaves when heated, scratched, washed, or worn.
Known failure modes — how the product actually breaks down in a real home.

What we don't do

We have not chemically tested this specific unit in a lab.
We don't take payment to rate a product higher — there is no sponsored placement.
We don't show star ratings or "trusted by thousands" counts we can't stand behind.

What gets a product rejected

Anything that adds a known microplastic, PFAS, or off-gassing source — a non-stick coating, a plastic surface against food or skin, vinyl/PVC — is downgraded or cut. We only list what clears that bar.

Common questions

Are they soft?

Yes — Coyuchi's 300-thread-count organic cotton has a crisp, clean feel that softens beautifully with each wash. Many people find organic cotton softer than polyester blends after just a few washes because the fibers relax naturally without synthetic stiffeners.

How do I wash them?

Machine wash in cold or warm water with mild detergent. Tumble dry on low. Avoid bleach and fabric softeners — organic cotton doesn't need them. The sheets actually get softer with each wash cycle.

Will they shrink?

Coyuchi pre-washes their sheets to minimize shrinkage. You may see 3-5% shrinkage after the first wash, which is normal for organic cotton. The sheets are sized to account for this. After the first wash, they'll stay stable.
