If you're waking up congested, itchy, or reaching for the antihistamines before you've even had breakfast, your mattress might be part of the problem.
For the 1 in 9 Australians living with asthma, and the millions more managing allergies, the bedroom isn't always the sanctuary it should be. Dust mites, mould, and bacteria can build up in bedding over time, and for sensitive sleepers, that build-up can mean disrupted sleep, irritated airways, and mornings that start with a sneeze.
Good sleep health isn't just about how many hours you clock: it's about waking up feeling your best. Choosing the right mattress can make a genuine difference, and knowing what to look for means you’re not left guessing.
Why your mattress matters for sleep health
A mattress is one of the few places in the home where you spend hours in constant, close contact with the same (relatively porous and absorbent) surface. That warmth and moisture from your body creates exactly the conditions dust mites need to thrive, and over time, mattresses build up a mix of dust mites, dead skin cells, sweat, and trapped moisture that's hard to see but easy to feel the effects of.
Dust mites themselves aren't usually the direct trigger. It's their droppings, along with mould spores and bacteria that grow in humid conditions, that carry the proteins most likely to set off a reaction. Breathing this in for hours every night can mean you wake up congested, sneezing, or with skin irritation that seems to clear up once you're away from the bed.
This is also why symptoms often feel worse overnight or first thing in the morning rather than during the day. You're in closer, more prolonged contact with these allergens than almost any other point in your day, and airways tend to be more reactive during sleep in general.
That's where material choice starts to matter as much as comfort or support.
Blue butterfly, black butterfly: what the Sensitive Choice logos mean
You may have spotted a small butterfly logo on some bedding products and wondered what it means. It's the Sensitive Choice symbol, a program run by the National Asthma Council Australia to help people identify products that have been independently reviewed for their potential benefit to people with asthma and allergies.
There are two versions of the logo, and the difference matters.
The Sensitive Choice blue butterfly is awarded to products that have been wholly assessed and endorsed as asthma and allergy aware. Dunlop Foams, who makes all the foams in our mattresses, carries the blue butterfly on its own foam products. Dunlop Foams has partnered with the National Asthma Council for close to 20 years, and that partnership has helped raise over a million dollars for asthma awareness and education.
The Sensitive Choice black butterfly means a product is made using a component or material that carries Sensitive Choice endorsement, without the finished product itself having gone through separate assessment. SleepMaker mattresses and pillows are made with Dunlop Foams' endorsed materials, including foam treated with Ultra-Fresh antimicrobials, which is why you'll see the black butterfly on our range rather than the blue one.
Alongside Sensitive Choice endorsement, Dunlop Foams also carries the AFRDI Blue Tick certification, an independent Australian standard covering safety, quality, and durability.
What to look for when choosing a mattress for allergies or asthma
Natural, breathable materials. Fibres like wool, silk,TENCEL®, and natural latex naturally resist common allergens and help wick away moisture, keeping your mattress drier and less hospitable to dust mites.
Antimicrobial treatment. Foams treated with antimicrobial technology like Ultra-Fresh® actively inhibit the growth of bacteria, mould, mildew, and fungi within the foam itself. Controlling these microbes also helps limit dust mite populations, since it disrupts the food source they rely on.
Independent certification. Look for the Sensitive Choice butterfly, along with certifications like AFRDI Blue Tick or GECA certification. These are a straightforward way to know a product has actually been assessed against a set standard, rather than just marketed as allergy-friendly.
Denser foam structures. Denser foams and latex layers give dust mites less room to establish themselves compared to traditional fibre fills.
The role of a mattress protector in protecting your sleep
A mattress protector does more than just guard against accidents and spills. It acts as a physical barrier between you and the mattress itself, helping keep dust mites, dead skin cells, sweat, and everyday debris from working their way into the foam and fibres underneath.
For allergy and asthma sufferers, this barrier is even more important. A heavy mattress can be difficult to clean at the best of times, but it’s especially hard to clean thoroughly once allergens have settled deep into it. A good protector stops most of that build-up from happening in the first place, and it's far easier to wash a protector regularly than it is to deep clean a mattress. Look for one that's breathable rather than fully sealed, so it doesn't trap heat and moisture against your skin overnight.
The importance of cleaning your mattress regularly
Even with a protector in place, your mattress benefits from regular attention:
Vacuum your mattress every few weeks using an upholstery attachment, paying particular attention to seams and edges where dust and skin cells collect. Regularly strip and wash your bedding and mattress protector in hot water to keep dust mite numbers down.
Deal with spills and stains as soon as they happen. Blot rather than rub, use a mild solution suited to your mattress fabric, and let it dry fully before making the bed again, since trapped moisture is exactly what mould and mildew need to take hold.
Air your mattress out when you can. Strip the bedding back and let the mattress breathe for a few hours, ideally with a window open. If you're able to get some sunlight on it occasionally, that helps too, since UV exposure has a natural drying and sanitising effect.
Rotate your mattress every few months to help it wear evenly, which keeps it supportive for longer and reduces the compressed, worn patches where moisture and allergens tend to gather.
When to replace your mattress
Sleep experts generally recommend replacing a mattress every 7 to 10 years, and sooner if you're a sensitive sleeper. If you're waking up with unexplained congestion, skin irritation, or noticing your mattress is visibly worn, sagging, or stained despite regular cleaning, it's a sign the materials underneath aren't doing their job anymore.
Finding the right fit for your sleep
Choosing a mattress for allergies or asthma is about finding one that works for your body's specific needs, using materials with certifications you can actually verify. And of course it needs to also be comfortable and supportive!

Allergy and asthma sufferer mattress FAQs
What is the Sensitive Choice black butterfly?
The black butterfly is used on products made with components or materials that carry a Sensitive Choice endorsement. Sleepmaker mattresses carry the black butterfly because they're made using Dunlop Foams' blue butterfly endorsed foams.
What's the difference between the blue and black Sensitive Choice butterflies?
The blue butterfly is awarded to products or components that have been wholly reviewed and endorsed as asthma and allergy aware. The black butterfly indicates a product uses an endorsed component or material, rather than the complete product having its own separate endorsement.
Are SleepMaker mattresses suitable for people with asthma or allergies?
SleepMaker mattresses are made with Dunlop Foams' Ultra-Fresh treated foam, which inhibits the growth of bacteria, mould, mildew, and fungi, and helps limit dust mite populations. Some ranges also use materials that are naturally hypoallergenic, like wool, silk, or latex.
Do mattress protectors actually help with allergies?
Yes. A mattress protector creates a barrier that stops dust mites, dead skin cells, sweat, and everyday debris from settling into the mattress itself. It's much easier to wash a protector regularly than to deep clean a mattress, making it one of the simplest ways to reduce allergen build-up.
How often should I clean my mattress if I have allergies?
Vacuum your mattress every few weeks, wash bedding and protectors weekly in hot water, and air the mattress out regularly. Deal with spills immediately, and aim to rotate the mattress every few months to keep wear, and allergen build-up, even across the surface.
How often should I replace my mattress?
Most mattresses should be replaced every 7 to 10 years. Sensitive sleepers should watch for earlier warning signs too, including unexplained congestion, skin irritation, or visible mattress wear, sagging, or staining despite regular cleaning.
What is Ultra-Fresh antimicrobial technology?
Ultra-Fresh® is an antimicrobial treatment applied to our mattress foams during manufacturing. It actively inhibits the growth of bacteria, mould, mildew, and fungi within the foam, which also helps limit dust mite populations by disrupting the food source they rely on.
