A more natural way to sleep.
Our bedrooms are increasingly filled with synthetic fibres — polyester sheets, microfibre bedding, polyester-filled mattress protectors, quilts and blankets.
If you'd prefer to sleep surrounded by natural materials, start with the fibres closest to your body.
Choose cotton for sheets and mattress protection.
Organic cotton for naturally comfortable bedding.
Australian wool for warmth.
Natural fibres where natural fibres work beautifully.
What Is Synthetic-Free Bedding?
Synthetic-free bedding is bedding designed primarily around natural fibres rather than manufactured synthetic fibres such as polyester, nylon and acrylic.
Natural bedding materials can include:
- Cotton
- Organic cotton
- Linen
- Wool
- Down and feather
For many people, the goal isn't to make a bedroom absolutely free of every synthetic component.
It's much simpler.
Reduce unnecessary synthetic fibres — especially in the bedding you sleep directly against every night.
That starts with understanding what's actually inside your bedding.
Is Polyester Common in Bedding?
Yes.
Polyester is inexpensive, durable, quick drying and resistant to wrinkles, which means it is widely used throughout the bedding industry.
You may find it in:
- Sheets
- Mattress protectors
- Quilts and doonas
- Pillows
- Quilt covers
- Blankets
- Throws
- Bedspreads
- Mattress toppers
Sometimes it is obvious.
Sometimes it isn't.
A product described as a cotton mattress protector, for example, may have a cotton outer fabric but polyester filling.
A sheet marketed as a cotton blend may contain a substantial percentage of polyester.
And microfibre bedding is generally made from synthetic fibres such as polyester or polyamide.
So if avoiding synthetics matters to you, don't rely only on the product name.
Read the fibre-content information.
LEARN MORE: WHAT IS POLYESTER?
Why Choose Bedding Without Polyester?
There isn't one single reason.
Different people choose natural-fibre bedding for different reasons.
1. Natural comfort
Cotton, linen and wool have been used in bedding for generations.
Cotton is naturally absorbent and familiar against the skin.
Linen can feel cool and relaxed.
Wool provides natural insulation while interacting effectively with moisture.
For something you spend around eight hours a night surrounded by, fibre choice matters.
2. Reduce plastic fibres in the bedroom
Polyester is a synthetic polymer.
In simple terms, it is a form of plastic spun into fibre.
If you're already trying to reduce unnecessary plastic throughout your home, bedding is a logical place to look.
Sheets and pillowcases sit directly against your skin.
Your mattress protector is immediately underneath you.
Quilts, blankets and covers surround you for hours every night.
Choosing natural fibres won't remove every piece of plastic from your home.
But it can significantly change the materials you choose to live and sleep amongst.
3. Reduce synthetic microfibre shedding
Synthetic textiles can release very small fibres through manufacture, use and washing.
These fibres can contribute to microplastic pollution.
Natural fibres aren't environmentally impact-free, but cotton and wool are fundamentally different materials from persistent synthetic plastic fibres.
Where a natural fibre performs the job beautifully, we think choosing it makes sense.
4. Better material transparency
Words such as:
soft
luxury
cooling
premium
eco
and even cotton
don't necessarily tell you what a product is actually made from.
The simplest question is:
What's in it?
If you're choosing synthetic-free bedding, look for clearly disclosed fibre composition rather than relying on marketing descriptions.
Start With the Bedding Closest to You
You don't need to replace everything in your bedroom at once.
If you'd like to reduce synthetic fibres, we recommend starting with the products closest to your body for the longest time.
1. Sheets and Pillowcases
Sheets make direct contact with your skin throughout the night.
Look for:
100% cotton
100% organic cotton
100% linen
rather than polyester, poly-cotton or microfibre sheets.
Our choice
Cotton and organic cotton sheets.
Soft, comfortable natural fibres designed for everyday sleeping.
2. Mattress Protectors
This is one of the easiest places to accidentally buy polyester.
Always check both:
the outer fabric
and
the filling.
A protector may have cotton on the outside while containing polyester padding inside.
Ecodownunder Organic Cotton Mattress Protectors use an organic cotton cover with natural cotton filling rather than polyester padding.

3. Quilts and Doonas
The filling is what matters most here.
Common synthetic quilts use polyester fibre filling.
Natural alternatives include:
- Australian wool
- Cotton
- Down and feather
We particularly like wool because it provides excellent warmth while being a natural fibre well suited to bedding.
SHOP AUSTRALIAN-MADE WOOL QUILTS
4. Quilt Covers
Your quilt cover surrounds the quilt and often sits against your skin.
Choose natural fibres such as:
- Organic cotton
- Cotton
- Linen
They are simple materials that have worked beautifully in bedrooms for generations.
5. Blankets, Coverlets and Throws
These are often overlooked.
Many soft or fleece-style blankets are made predominantly from polyester or acrylic.
If you're creating a more natural bedroom, look instead for cotton and wool.
Natural materials also add the texture, character and relaxed feel that make a bedroom feel like home.

Natural Fibre vs Synthetic Bedding
| Natural Fibre Bedding | Synthetic Bedding | |
|---|---|---|
| Typical fibres | Cotton, linen, wool | Polyester, nylon, acrylic |
| Raw material | Plant or animal fibre | Manufactured polymer |
| Polyester | No, when specified as 100% natural fibre | Often |
| Moisture interaction | Depends on natural fibre; cotton readily absorbs moisture | Polyester absorbs relatively little moisture |
| Synthetic microplastic fibres | Natural fibres aren't synthetic plastic | Synthetic textiles can shed plastic microfibres |
| Feel | Varies naturally by fibre and weave | Can be engineered into many different feels |
| Wrinkle resistance | Usually lower | Often higher |
| Drying time | Often slower | Usually faster |
| Price | Varies by quality and fibre | Often inexpensive |
| End-of-life | Depends on dyes, finishes and construction | Synthetic polymer persists unless recycled or otherwise processed |
Neither category makes every product automatically good or bad.
Our preference is simpler:
Where natural materials can perform the job beautifully, choose natural materials.
How to Tell if Bedding Contains Synthetic Fibres
Don't judge bedding by how it looks or feels.
Read the composition.
Look for synthetic terms including:
- Polyester
- Recycled polyester
- PET
- Nylon
- Polyamide
- Acrylic
- Polypropylene
- Microfibre
- Poly-cotton
- Polyester blend
Look for natural fibres including:
- Cotton
- Organic cotton
- Linen
- Wool
- Silk
- Down
- Feather
And remember:
“Cotton” on the front doesn't necessarily mean 100% cotton.
Look for the actual fibre composition.
Is Microfibre Bedding Synthetic?
Usually, yes.
Microfibre describes extremely fine fibres rather than the raw material itself.
Most microfibre bedding is manufactured from polyester, polyamide or combinations of synthetic fibres.
That means an exceptionally soft microfibre sheet can still be made predominantly from plastic-derived fibre.
If your objective is to avoid synthetic bedding, look at the fibre composition rather than relying on softness or marketing names.
What About Recycled Polyester?
Recycled polyester has advantages over virgin polyester because it can reduce the requirement for newly manufactured fossil-derived polyester.
But recycled polyester is still polyester.
It remains a synthetic polymer rather than becoming a natural fibre.
Our view is:
Where synthetic fibre is genuinely necessary, recycled polyester can be preferable to virgin polyester.
But where cotton, wool or another natural fibre already does the job well, we'd rather use nature.
Do I Need to Throw Away My Existing Synthetic Bedding?
No.
Living with Nature isn't about pursuing perfection.
And replacing perfectly usable products simply creates more waste.
A more sensible approach is:
Use what you already own.
Then, when something eventually needs replacing:
Choose better.
One sheet set.
One mattress protector.
One quilt.
One towel.
Over time, your home naturally becomes a little more natural.

Synthetic-Free Bedding and Living with Nature
At Ecodownunder, we've believed in natural materials since 1997.
Living with Nature doesn't mean trying to create a perfect home.
It means looking at the choices we make every day and asking whether nature already provides a better solution.
For bedding, it often does.
Cotton for softness.
Wool for insulation. Warm in winter, cool in summer.
Natural fibres against the body.
Durable products designed to be enjoyed for years.
Buy what you need. Choose it well. Look after it.
That's our idea of a more natural home.
Frequently Asked Questions
What is synthetic-free bedding?
Synthetic-free bedding generally refers to bedding made from natural fibres rather than synthetic fibres such as polyester, nylon and acrylic. Common natural bedding fibres include cotton, organic cotton, linen and wool. Check the full fibre composition because some products combine a natural outer fabric with synthetic filling or other components.
What bedding doesn't contain polyester?
Bedding made from clearly specified natural fibres can avoid polyester. Examples include 100% cotton sheets, organic cotton quilt covers, cotton-filled mattress protectors and wool-filled quilts. Always check individual product specifications because construction varies.
What are the best sheets without polyester?
Look for sheets clearly labelled 100% cotton, 100% organic cotton or 100% linen. Avoid polyester, poly-cotton and polyester microfibre if your objective is to sleep in natural fibres.
Are cotton sheets polyester-free?
Sheets labelled 100% cotton should have cotton as their textile fibre composition. Products simply described as “cotton sheets” may sometimes be blends, so check the detailed fibre-content information before purchasing.
Is microfibre bedding polyester?
Most household microfibre bedding is manufactured from polyester, polyamide/nylon or blends of synthetic fibres. “Microfibre” describes fibre size rather than identifying a natural raw material.
Is poly-cotton synthetic?
Poly-cotton is a blend of natural cotton and synthetic polyester. For example, a 50% cotton / 50% polyester sheet contains approximately half polyester by fibre composition.
Are polyester sheets plastic?
Polyester is a synthetic polymer. The polyester commonly used in textiles is generally polyethylene terephthalate, or PET, a form of plastic.
Is recycled polyester natural?
No. Recycling changes the source of the material but not the fundamental fibre. Recycled polyester remains a synthetic polyester fibre.
What is a natural alternative to a polyester quilt?
Wool, cotton and down or feather can all be used as natural quilt fillings. Ecodownunder specialises in Australian-made wool quilts as a natural alternative to polyester-filled quilts.
Can mattress protectors contain polyester even if they say cotton?
Yes. Some mattress protectors use cotton in the outer fabric but polyester within the quilted padding or filling. Check both the outer fabric and internal filling if avoiding polyester is important to you.
Is natural bedding better for hot sleepers?
Fibre selection can influence moisture and heat management, but fabric construction, weave, room temperature, mattress and individual physiology also matter. Cotton absorbs moisture readily, while polyester absorbs relatively little into the fibre itself. Many people therefore prefer natural-fibre bedding when seeking a less clammy sleeping environment.
Should I replace all my synthetic bedding?
Not necessarily. We recommend using serviceable bedding rather than unnecessarily creating waste. When each item eventually needs replacing, choose natural fibres if they suit the purpose.
Does Ecodownunder sell synthetic-free bedding?
Ecodownunder specialises in bedding made predominantly from natural fibres including cotton, organic cotton and Australian wool. Because small functional components can vary by product, check individual product specifications where avoiding every synthetic component is important.
What's the easiest way to create a more natural bed?
Start with the products closest to your body: sheets and pillowcases. Then consider your mattress protector, quilt, quilt cover and blankets as they need replacing. Choosing natural fibres progressively is an easy way to reduce unnecessary synthetics without creating additional waste.
