The mattress cover is often overlooked, yet it serves as an essential barrier against sweat, dust mites, and allergens. Proper maintenance improves your sleep quality and extends the lifespan of your mattress. Here are our clear and practical tips.

What is a mattress cover?

The mattress cover (also called a ticking) is the first textile layer that wraps around the mattress:

  • Protects against moisture, sweat, and stains
  • Limits the accumulation of dead skin, a source of allergens
  • Prevents the proliferation of dust mites, bacteria, mold

More and more mattresses today come equipped with removable covers that are machine washable.

Different types of protections

Removable cover

  • With zipper
  • Machine washable
  • Main barrier against allergens and dirt

Full cover

  • Envelops the entire mattress
  • Often waterproof and dust mite resistant

Mattress protector (or mattress pad)

  • Placed on top of the cover
  • Washable more frequently
  • Extends the cleanliness of the main cover

Common materials

  • Cotton: natural, breathable, hypoallergenic
  • Polyester: durable, but less breathable
  • Technical blends (polyurethane, Tencel, etc.): waterproof and often dust mite resistant

How often to wash the mattress cover?

Type of protectionRecommended frequencyFor whom?
Mattress cover1 to 2 times/year (normal use)All sleepers
Every 2–3 monthsAllergic individuals, pets, heavy sweating
Immediately after an accidentStains, urine, vomit
Mattress protector / padEvery 2 to 4 weeksChildren, allergic individuals
Mattress topper1 to 2 times/yearSleepers seeking extra comfort and support

Washing too frequently can damage the fibers or treatments (dust mite resistance, waterproofing).

Risks of poor maintenance

  • Proliferation of dust mites → allergies, asthma, eczema
  • Mold due to moisture → health risk
  • Premature wear of the mattress and unpleasant odors

Best practices for maintaining your cover

  • Air the room every day
  • Vacuum the mattress (if the cover is non-removable) once a month
  • Follow washing instructions:
    • 30–40 °C (up to 60 °C if allowed)
    • Gentle spin
    • Drying in the open air, flat if possible
  • Use a gentle liquid detergent
  • Pre-treat stains locally (black soap, baking soda, white vinegar)
  • Never put a damp cover back on the mattress

For optimal protection, a suitable mattress protector provides an additional layer that can be washed more often, thus preserving the mattress cover and extending its lifespan. You can also complement maintenance with a regular cleaning of the mattress itself .

Common mistakes to avoid

  • Washing too hot or too often without necessity
  • Using bleach or harsh solvents
  • Neglecting the mattress protector, which can be washed more often

Protecting and maintaining your bedding — to avoid premature wear of the main cover, adding a washable mattress protector remains the best approach.

FAQ

How often should I wash the mattress cover?For standard use, 1 to 2 washes per year are sufficient for a removable cover. This frequency may seem low, but it protects the technical fibers and dust mite treatments, which degrade with each wash cycle. However, if you are allergic to dust mites, sleep with a pet, or sweat heavily at night, switch to washing every 2 to 3 months to limit bacterial colonization and allergen accumulation. And of course, wash immediately after an accident (urine, vomit, blood stain) to prevent the stain from penetrating the mattress itself.
What about the mattress protector?The mattress protector (or pad) is washed much more often than the main cover: generally every 2 to 4 weeks, or immediately when soiled. This is precisely its role: to act as a barrier between your body and the mattress's integrated cover to absorb most fluids and sweat. For children, allergic individuals, or in cases of significant nighttime sweating, reduce to weekly washing. Choose a model made of 100% cotton or Tencel for breathability, and prefer versions with a waterproof micro-perforated polyurethane underlayer: they block liquids while allowing air to pass through.
Can all covers be machine washed?Most removable covers on modern mattresses (Emma, Tediber, Someo, Hypnia, etc.) are designed for machine washing, typically at 30 or 40 °C. However, this is not always the case: some technical covers treated for fire resistance, antibacterial properties, or made of wool can only be dry cleaned or require hand washing. Always check the label or the manufacturer's product sheet before the first wash. In case of doubt, a local cleaning with a damp cloth and mild soap remains the safest solution. For large covers, also check the drum diameter: at least 7 kg capacity is needed for a king-size mattress cover.
At what temperature should I wash?30 to 40 °C for most covers. Up to 60 °C if the label allows, which effectively eliminates dust mites and bacteria.
Should I use a dryer?Not recommended for most covers. The heat from the dryer distorts elastic fibers, can damage dust mite treatments, and cause the fabric to shrink, making it difficult to reposition. Prefer natural drying, flat on a rack or hung outside, away from direct sunlight (which yellows white cotton). Allow 24 to 48 hours for complete drying depending on ambient humidity. Never put a cover back on the mattress even slightly damp: residual moisture immediately promotes mold growth inside the mattress, which can sometimes be irreversible.
What products are recommended?A **gentle liquid detergent**, without optical brighteners. For stains: black soap, white vinegar, baking soda.
Why is this important for sleep?A clean cover limits allergens, avoids odors, and promotes deeper and more restorative sleep.
