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, and 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

  • Envelopes 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…): waterproof and often dust mite resistant

How often should you 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 / mattress 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).

The best way to space out washes of the integrated cover — which is often difficult to remove and replace — is to add a washable mattress pad or protector on top, which absorbs sweat and dirt for you and is much easier to machine wash.

Risks of poor maintenance

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

Best practices for maintaining your cover

  • Air out the room every day
  • Vacuum the mattress (if the cover is not removable) once a month
  • Follow washing instructions:
    • 30–40 °C (up to 60 °C if allowed)
    • Gentle spin
    • Dry 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 frequently

Protecting and maintaining your bedding: a layer of protection that can be washed more often than the cover is the best investment for keeping a mattress healthy.

FAQ

How often should you wash the mattress cover?For standard use, washing the mattress cover 1 to 2 times a year is sufficient to maintain good hygiene. However, this frequency should be increased to every 2 to 3 months in several cases: if you suffer from dust mite allergies, if you sleep with a pet, if you sweat a lot at night, or during hot summer weather. And of course, any accident (stains, spilled liquids, illness) requires immediate washing. However, be careful not to fall into the opposite excess: washing too often and too hot can degrade the fibers and the dust mite or waterproof treatments. The best strategy remains to intersperse a washable mattress pad more frequently to protect the cover itself.
What about the mattress protector?Every 2 to 4 weeks, or as soon as it gets dirty.
Can all covers be machine washed?Most modern removable covers, equipped with a zipper, are designed to be machine washed — but this is not a universal rule. Some treated covers (water-repellent, waterproof, memory foam) or those with a membrane may be damaged by a regular wash or too vigorous spinning. Before any washing, be sure to check the care label sewn onto the cover: it indicates the maximum temperature, recommended program, and any prohibitions (dryer, bleach, ironing). In the absence of a label or in case of doubt, prefer a gentle wash at 30 °C and air drying, which pose almost no risk to the fabric.
At what temperature should you wash?For most covers, washing at 30 to 40 °C is ideal: it cleans effectively without damaging the fibers or deteriorating the technical treatments. If the label allows it, washing at 60 °C is particularly recommended for allergic individuals, as this temperature eliminates almost all dust mites and their droppings, the main culprits of allergic reactions. However, never exceed the temperature indicated by the manufacturer: excessive heat can shrink the fabric, deform a waterproof membrane, or nullify a dust mite treatment. For delicate covers or those not washable at high temperatures, an effective alternative is to place them in the freezer for a few hours, which also kills dust mites.
Should you use a dryer?Not recommended. Prefer **natural drying**, flat and in the open air.
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.
