Preparing Your Mattress Topper Before First Use

Before placing your mattress topper on the bed for the first time, it’s always best to freshen it up with a light airing and sunshine. If you’re wondering how to care for a mattress topper from day one, wool makes it wonderfully simple. We always recommend airing your mattress topper before first use. This helps to naturally refresh and revitalise the wool fibres after being stored in packaging.

Do you need to wash a mattress topper before first use? With wool, the answer is no – there’s no need to wash it before use. Simply let nature do the work for a beautifully fresh start.

Can you wash a Mattress Topper

A wool mattress topper can be washed if needed, but one of wool’s unique benefits is it’s simple care. Regular washing isn’t usually necessary – a simple airing is often all it takes to keep it fresh and comfortable.

But yes a wool mattress topper can be washed. However, it’s not our preferred cleaning method, one of wool’s best caring features is that it LOVES fresh air and sunshine, so regular washing isn’t required.

If you’re wondering, can I put my mattress topper in the washing machine, the answer is that while it’s possible in most cases, airing is often all that’s needed to keep it fresh. Simply air your mattress topper outside a few times a year on a warm breezy day. This allows moisture and odours to release naturally and helps maintain the wool’s performance.

For a little extra freshness, we recommend a light spritz of water or MiniJumbuk Wool Spray before airing. This helps the topper further and restores the natural loft of the wool fibres.

How Often Should You Wash Your Mattress Topper

Wool naturally resists odours and moisture, meaning frequent washing isn’t needed and it’s best kept fresh with regular airing. Simple airing does wonders for a wool mattress topper, aim to air outside on breezy day whenever possible.

Fresh air and sunshine will revitalise the wool fibres, release any trapped moisture and help prevent odours. When considering how often should I wash my mattress topper, washing is only necessary if there’s a noticeable odour or stain. Our mattress toppers can be machined washed when needed, making care simple and quick.

How to Wash a Mattress Topper at Home

When washing is required, we recommend a gentle machine wash ensuring the correct care instructions are followed. While regular washing isn’t necessary, can you wash a mattress topper? Yes – our mattress toppers are machine washable.

Follow our simple step-by-step guide on how to wash a mattress topper.

Check the Care Label
Always read the care instructions on your wool mattress topper. Wool is sensitive to heat and agitation, so following the label will keep your product in good condition.
Choose the Right Machine
For smaller sizes (single, double), a home front loader washing machine works okay. For larger sizes (queen, king or super king) we recommend a commercial machine that can fit the topper comfortably without excessive agitation.
Use a Wool-Friendly Detergent
Select a detergent designed for wool, such as MiniJumbuk Wool Wash. Avoid regular detergents as they can damage wool fibres.
Select the Right Temperature and Cycle
Wash in warm (40°C) water. Avoid hot water and aggressive cycles, they can damage the wool fibres.
Handle with Care During the Wash
Make sure your machine isn’t overloaded for a gentle clean.
Rinse Thoroughly
Fully rinse all detergents to maintain the softness and natural properties of the wool.
Dry Naturally
Lay your topper flat on a clean, dry surface or a drying rack. Avoid tumble drying. Air and sunshine will help restore the loft and freshness of wool fibres.
Restore Fluffiness
After washing the wool pile may chance in appearance and the wool may flatten, reassure this is completely normal and will not affect the performance of your mattress topper. Gently brush across the fleecy surface (using a wire pet brush, wide-tooth comb or vacuum cleaner).

How to Dry and Air Your Mattress Topper Naturally

To keep your wool mattress topper fresh and comfortable, regular natural airing is key. Place it outside on the clothesline, dry rack or any clean surface that will allow fresh air to pass through the topper. Fresh air and sunlight will naturally refresh the wool fibres. When airing, flip and rotate your mattress topper to ensure all areas are evenly aired and any trapped moisture is released.

Avoid using a tumble dryer, direct heaters or damp/cold enclosed spaces. Excess heat or moisture can damage the wool and is best to avoid during the cleaning process.

After airing, gently shake or brush the topper to restore its natural loft and fluffiness. Regularly following these steps for how to air a mattress topper naturally and how to dry a mattress topper will help maintain comfort, hygiene and the long term performance of your wool mattress topper.

When Should You Dry Clean a Mattress Topper?

Dry cleaning a wool mattress topper is rarely needed but is sometimes the preferred cleaning method. For most households, do you need to dry clean a mattress topper? The answer is no – especially when using a wool mattress topper that naturally breathes and is easy to care for.

MiniJumbuk wool mattress toppers are designed for simple home care, however it is also safe to dry clean, if you wish. If mattress topper dry cleaning is needed, it’s best for the dry cleaner to carefully follow the care labels on the product to ensure no damage.

If you wish to dry clean:

Always ask the dry cleaners to follow the care label that is attached to the mattress topper.
We recommend, choosing a member of the Dry Cleaners Institute of Australia.
Proper handling helps preserve the wool’s natural softness and resilience. Some stains (like sweat) may set during dry cleaning.

Dry cleaning can be a good option for stubborn stains or a deeper refresh, but always check with your cleaner first, as older stains may not fully lift. Knowing how to clean a wool mattress topper properly helps keep your MiniJumbuk product fresh and comfort for years.

Spot Cleaning Wool Mattress Toppers

When small spills or marks appear, spot cleaning is often the best option and helps avoid unnecessary full washes. If your mattress topper doesn’t require a complete wash, a quick spot clean is a simple way to freshen the surface when learning how to clean a mattress topper properly. To avoid permanent marks, it’s essential to attend to any spills or stains immediately.

We recommend Woolmark’s Spot Cleaning Mix:

1 tsp wool detergent
1 tsp white vinegar
1L warm water

How to Spot Clean a Mattress Topper:

Dip a clean cloth into the solution
Gently dab the affected area
Avoid rubbing, as this can damage the wool fibres or spread the stain
Air dry naturally

Remember to ensure the product is completely dry before placing back on your bed. Wool naturally absorbs moisture and can often feel dry on the surface.

The Woolmark Company has many great tips and methods for more targeted stains, such as coffee, blood or vomit. Visit the Woolmark website for more details. Spot cleaning your mattress topper helps maintain cleanliness while preserving the structure, comfort and performance of your wool bedding.

Our easy tips on how to store a mattress topper and keep it in great condition long term.

Regular Cleaning Routine

Regular care and upkeep will prolong the life of your mattress topper.

Vacuum your mattress topper every few months to remove dust, skin cells and rejuvenate the wool pile.
Regularly launder your sheets.
Consider high quality breathable bedding.
Add a mattress protector to help extend the life of your mattress and topper. We recommend placing the mattress protector under the topper so you still achieve the benefits of sleeping on natural wool.

Flip with the Seasons

Our mattress toppers are reversible so you can enjoy wool year round. When searching for cooler sleep during the warmer months, simply flip your mattress topper and enjoy the smooth cotton casing side.

Before Storing

Before storing your mattress topper, make sure it is clean and completely dry. This is important to avoid mould, mildew and odour during the storing period. Airing it outside on a sunny, breezy day is ideal to ensure any moisture has fully released and the wool remains fresh.

How to Store Wool Correctly

Store your mattress topper in a cool, dry and well-ventilated area. Avoid damp spaces as the extra moisture can be absorbed by the wool fibres. We recommend storing in a breathable bag, consider cotton or linen.

Long-Term Storage Tips

Using moth-repellent sachets can be handy for long term storage but avoid direct contact with the wool. Always check the mattress topper regular to make sure it remains dry.

Using After Storage

After your mattress topper has been stored away it’s always a good idea to refresh the wool fibres with a little airing and sunshine. If you want extra freshness, spray the product with some MiniJumbuk Wool Spray during the airing process. Remember to always make sure it’s full dry before placing back on the bed.

Overtime, after washing or storing the wool pile may change in appearance and the wool may flatten – this is completely normal. Restore the soft, fluffy appearance with a gentle brush across the fleecy surface using a wire pet brush, wide-tooth comb or a vacuum cleaner. Brushing or a quick vacuum will also help to remove any loose fibres.

Can I machine wash a mattress topper?

Mattress toppers can be machine washed. Follow the care labels correctly to avoid damaging the natural wool fibres. Spot cleaning might be a better alternative than a full machine wash.

We recommend the Woolmark Mix:

1 tsp wool detergent
1 tsp white vinegar

Wool needs room to move during the washing process; too much agitation will damage the soft fibres. If you must squeeze your mattress topper in the machine, it’s best to use a commercial-sized front loader to avoid any damage to your product.

How to remove yellow stains from mattress topper?

Spot Cleaning is the best cleaning method to remove any stains, such as yellowing. Before spot cleaning give the stain a quick vacuum to remove any loose fibres like dirt or dust. Use the Woolmark Sort Cleaning Mix – 1tsp wool detergent, 1tsp white vinegar in 1L of warm water. Lightly dab or blot the stain with mixture, avoid rubbing or excessive amounts of liquid. Allow the treated air to completely dry naturally.

How do I keep it fluffy/supportive?

Overtime your woollen mattress topper may change in appearance and the wool may look a little flatter – reassure this is completely normal. To bring back its soft, fluffy feel, simply give it a gentle brush across the surface with a wire pet brush, wide tooth comb or even a vacuum. A quick brush or vacuum will also help lift any loose fibres, keeping your topper looking and performing at it’s best.

Can I put a wool mattress topper in the dryer?

No, we don’t recommend using a dryer, as high heat and tumbling can harm the wool fibres. Instead, let your mattress topper air dry naturally by laying it flat outside, on the clothesline or on a drying rack.
