How to Keep Your Child’s Mattress Clean and Hygienic

Your child spends around 10 to 12 hours a night sleeping—so keeping their mattress clean and hygienic is more important than most parents realise. From dust mites to accidental spills, a kids mattress can quickly become a breeding ground for bacteria and allergens. Here’s how to maintain a fresh and healthy sleep environment for your little one.

Why Mattress Hygiene Matters for Kids

Children are more sensitive to allergens, bacteria and mould than adults. A dirty mattress can contribute to:

  • Asthma or allergy flare-ups

  • Skin irritations or rashes

  • Disrupted sleep

  • Unpleasant odours

Maintaining mattress hygiene not only improves their health but also extends the lifespan of the mattress itself—saving you money in the long run.

Use a Waterproof Mattress Protector

A good-quality waterproof mattress protector is your first line of defence. It acts as a barrier against:

  • Bedwetting accidents

  • Spilled drinks

  • Sweat and body oils

  • Dust mites and allergens

Look for a protector that’s breathable, machine-washable and fitted securely to avoid bunching. Wash it every 2–4 weeks, or immediately after an accident.

Wash Bedding Regularly

Even with a mattress protector, your child’s sheets, pillowcases and blankets collect dust, skin cells and bacteria. Make sure to:

  • Wash sheets and pillowcases weekly

  • Wash blankets and duvet covers every 2–3 weeks

  • Use hot water (60°C or higher) to kill dust mites and bacteria

  • Choose hypoallergenic laundry detergents for sensitive skin

Regular bedding changes help keep the mattress underneath cleaner for longer.

Vacuum the Mattress Surface

Vacuuming isn’t just for carpets. Use your vacuum’s upholstery attachment to:

  • Remove dust, hair and crumbs

  • Minimise allergens

  • Freshen the mattress surface

Aim to vacuum the mattress every 1–2 months, or more frequently if your child suffers from allergies or asthma.

Spot Clean Stains Promptly

Spills and accidents happen—but quick action prevents long-term stains and smells.

  1. Blot (don’t rub) the spill with a clean cloth to soak up excess liquid.

  2. Mix a mild solution of detergent and water, and gently dab the stain.

  3. Use a clean damp cloth to rinse away residue.

  4. Allow to air dry completely before remaking the bed.

Avoid soaking the mattress, as excess moisture can lead to mould or mildew.

Deodorise Naturally

Over time, mattresses can start to smell—especially in warm, humid climates. Banish odours with natural ingredients:

  • Sprinkle baking soda evenly over the surface

  • Let it sit for 4–6 hours (or overnight)

  • Vacuum thoroughly to remove all residue

You can also add a few drops of child-safe essential oil (like lavender or eucalyptus) to the baking soda for a fresh scent.

Rotate the Mattress Regularly

Mattresses can wear unevenly, especially if your child tends to sleep in one position. To help it last longer and stay comfortable:

  • Rotate the mattress head-to-foot every 3 months

  • If it’s double-sided, flip it as well

  • Check for signs of sagging or lumps

Even wear helps maintain proper support and reduces the risk of pressure points or dips.

Let It Breathe

Airflow is essential to keep moisture and odours at bay. Every few weeks:

  • Strip the bed completely

  • Let the mattress air out for a few hours

  • Open windows to boost ventilation

  • Avoid placing heavy blankets or toys on the mattress during the day

This simple step reduces the build-up of humidity and helps prevent mould.

Choose the Right Bed Base

The mattress base can also affect hygiene. A solid or slatted frame allows for better airflow and keeps the mattress off the ground, reducing exposure to dust, dirt and pests.

  • Ensure slats are no more than 7 cm apart

  • Avoid placing mattresses directly on the floor

  • Check for mould or dust under the bed regularly

A well-ventilated bed base plays a big part in keeping the mattress dry and fresh.

Protect Against Bed Bugs and Dust Mites

Mattresses are notorious hiding spots for tiny pests. To reduce the risk:

  • Use dust-mite-proof covers on mattresses and pillows

  • Wash bedding in hot water

  • Vacuum regularly, including under the bed

  • Keep soft toys clean and wash them often

If you suspect a bed bug infestation, contact a professional pest control service promptly.

Replace the Mattress When Needed

Even with great care, children’s mattresses don’t last forever. Signs it might be time for a new one include:

  • Persistent odours or stains

  • Visible sagging or lumps

  • Increased allergy symptoms

  • Your child complains of discomfort

Most children’s mattresses last around 7–10 years, but this can vary based on quality and usage.

Maintaining a clean and hygienic mattress is an essential part of your child’s overall sleep health. With a few regular habits and the right protective products, you can ensure their bed stays fresh, healthy and comfortable—night after night.
