How To Look After Your Natural Mattress

I’ve put together this practical care guide to help you get the most out of your natural mattress, keeping it fresh, supportive, and comfortable for years to come. 

Taking care of your natural mattress is simple, and with a little regular maintenance, you’ll keep it feeling fresh, supportive and comfortable for years to come.

I’m Hannah Shore, Mattress Online’s Head of Sleep Science, and I’m here to share simple, effective tips to help you look after your mattress with ease.

Air your mattress out

Air out your mattress for at least 20 minutes every morning. Instead of making your bed straight away, pull back the duvet to let fresh air circulate while you get ready.

When changing your sheets, give your mattress a bit more time to breathe - ideally, a few hours. This helps to:

• Release moisture absorbed overnight (especially important for wool and cotton fillings, which naturally absorb moisture, but take some time to dry out)
• Prevent musty odours from developing
• Keep the internal layers fresh and dry

Simply open your bedroom window in the morning and let nature do the rest.

Keep your mattress clean

To maintain a hygienic sleeping surface, gently vacuum your natural mattress using a soft brush attachment. This helps remove dust, skin cells, and allergens from the top layer without damaging the fibres inside of your mattress.

For spills or stains, use a mild detergent and a damp cloth to gently spot clean the area. You should always Avoid soaking the mattress or using harsh chemicals, as these can cause damage.

Regular cleaning helps maintain a hygienic sleeping environment and preserves the quality of your mattress:

• Vacuum the mattress surface using a soft brush attachment to remove dust, dead skin cells, and allergens
• Spot-clean spills or stains with a mild detergent and a damp cloth - remember to gently blot the affected area, don’t rub the stain deeper into the mattress cover
• Avoid soaking the mattress or using harsh chemicals, which can damage the natural fibres inside

Rotate or flip your mattress regularly

Over time, the natural fillings will settle, especially in the areas where you sleep the most - don’t worry, this is normal. To help your mattress wear evenly, rotate it from head to toe at least every 4–6 weeks.

If you have a double-sided mattress, flip it over at the same time to spread out the pressure and maintain its structure and support.

Not sure if your natural mattress is single- or double-sided? Check the care label or the manufacturer’s instructions. Or, you can get in touch with our helpful Customer Service Team, and we can find out for you.

Extra care tips for your natural mattress

A few small habits can make a big difference in keeping your mattress at its best. Here’s what I like to recommend:

• Plump your mattress each time you change your sheets. While you can’t lift your mattress like a cushion, running your hands over the surface can help redistribute the fibres and keep it feeling fresh.
• Use a breathable mattress protector to keep it clean without trapping moisture.
• Avoid sitting in the same spot repeatedly, such as the edge, to prevent uneven compression.
