Yes, you can put a king-size doona in a 7kg washing machine—**but only under the right conditions. And if you’ve ever tried to stuff one in, you’ll know it’s less about “can” and more about should. Here’s the deal: while it’s technically possible, doing so without checking a few key things could leave you with a soggy lump of regret and a potentially overworked machine. Below, we’ll unpack the dos, don’ts, and dryer dilemma that comes with washing a big doona in a not-so-big washer.

Is a 7kg Machine Big Enough for a King-Size Doona?

A 7kg washing machine is often considered standard for smaller households. But throw a king-size doona into the mix, and you’re testing its limits.

Let’s crunch the fluff

• Weight when dry: Most king-size doonas weigh 2–4kg.

• Weight when wet: Can double or triple after soaking up water—easily hitting 6–9kg.

• Machine strain: Overloading risks inefficient cleaning, unbalanced spin cycles, and motor wear.

Verdict? A lightweight summer doona may squeeze in. A plush winter one? Not a chance without cutting corners (and we’re not suggesting scissors).

What Happens If You Overstuff the Washer?

Stuffing in a bulky doona might feel like a win—until you hit spin cycle.

Here’s what can go wrong:

• Uneven cleaning: Water and detergent can’t circulate properly, leading to dirty patches or detergent stains.

• No spin, no dry: The washer may fail to spin properly, leaving the doona soaked.

• Damage risk: Prolonged strain on the motor can shorten your machine’s lifespan. That warranty? Probably void.

Anyone who’s wrestled a dripping doona out of a mid-cycle machine knows—this isn’t just a washing fail, it’s a workout.

Which Doonas Can Go in a 7kg Washer?

The trick is knowing your doona’s size and fill.

You’re likely safe with:

• Lightweight microfibre doonas

• Low-fill cotton or bamboo quilts

• King doonas rated as ‘machine-washable’ and weighing under 3kg

Before you wash, always check:

• The care label (if it says “dry clean only,” take it seriously)

• The loft (fluffiness = bulk)

• The fabric (some synthetics retain more water)

What’s the Better Alternative?

If your doona barely fits—or you have to force the door shut—it’s time for a plan B:

• Use a laundromat’s industrial machine. These machines typically hold 10–18kg and are designed for bulky loads.

• Opt for professional cleaning. Especially for down-filled or feather doonas that need delicate care.

• Wash it seasonally. The less often you wash it, the less strain you put on your gear—just make sure you’re airing it regularly between washes.

Fun fact? The CSIRO recommends regular airing of doonas to reduce dust mites and extend their lifespan. Sunlight = nature’s dry cleaner.

Can You Put a Doona in the Dryer After Washing?

This is where things get toasty—and a bit risky.

Yes, but…

Only some doonas can go in the dryer safely. And it’s not just about temperature—it’s about time, type, and tumbling.

You’ll need to:

• Use a low heat setting. High heat can warp synthetic fibres or shrink natural ones.

• Add dryer balls or tennis balls. They help keep the filling evenly distributed.

• Dry in intervals. Every 20–30 minutes, pause and fluff it manually.

• Double-check it’s completely dry. Damp patches breed mould faster than you’d think.

For doonas that shouldn’t go in a dryer, your best bet is line drying on a warm, breezy day. Be prepared for it to take several hours—if not all day.

What’s the Risk of Not Drying It Properly?

Drying a doona isn’t just about comfort—it’s about hygiene.

• Trapped moisture can lead to mildew growth inside the fill.

• Feathers or down can clump and smell musty.

• Synthetic fibres may degrade or mat down unevenly.

It’s one of those jobs that’s worth doing right the first time—unless you’re keen on repeat laundry marathons.

What Size Washer Should You Use for a King Doona?

Most experts agree: if you’re regularly washing large bedding, aim for a 9kg–10kg machine minimum.

Real Talk: Doonas, Dryers and Domestic Drama

We’ve all been there. You get ambitious, cram the doona in, shut the lid, and walk away with that “she’ll be right” confidence. Only to return to a washing machine that sounds like a jet engine—or worse, one that won’t spin at all.

My neighbour tried to dry a queen doona in her small dryer. Three hours later? It was warm… but wet in the middle. The next morning? Musty smell city.

Lesson learned: size, fill, and drying method matter.

FAQ

Can I wash a king-size wool doona in a 7kg washer?
Unlikely. Wool is bulky and absorbs more water. You’re better off using a commercial washer or dry cleaning.

Is air-drying better than tumble drying for doonas?
If done properly, yes—especially for feather or down fill. But it requires time, airflow, and sun.

What if my washing machine won’t spin my doona?
It’s likely unbalanced. Stop the cycle, redistribute the weight, and try again. Or consider a smaller load.

Final Thoughts

Washing a king-size doona in a 7kg machine? Technically possible—but not ideal. You risk poor cleaning, waterlogging, and damaging your appliance. If your doona’s lightweight and labelled machine-washable, you’re probably fine. But for anything bulkier, you’re better off heading to the laundromat or using a larger-capacity washer.

And if you’re planning to dry it afterwards, make sure you understand whether putting a doona in the dryer is safe—or a shortcut to damp disappointment.
