Can You Dry a Mattress Cover? Safe Ways to Dry Different Types

If you’ve just washed a mattress cover, you might be wondering: Can you dry a mattress cover in the dryer, or will it shrink or get damaged? This guide explains what’s safe, what to avoid, and how to dry different types of covers without ruining them.

Can You Dry a Mattress Cover at All?

In most cases, yes, you can dry a mattress cover—but how you dry it depends on:

  • The material (cotton, polyester, waterproof, quilted, etc.)
  • Whether it has a waterproof backing or membrane
  • The care instructions from the manufacturer

The safest first step is always to check the care label. This will usually tell you if the cover can go in the dryer, at what temperature, or if it needs to be air-dried only.

Can You Dry a Mattress Cover in the Dryer?

When is machine drying safe?

Many fabric-only mattress covers (like basic cotton or polyester covers with no waterproof layer) can be dried in a machine on:

  • Low or medium heat, and
  • Gentle or normal cycle

If the label shows a dryer symbol with one or two dots, that typically means low or medium heat is recommended.

When to avoid the dryer

Be especially careful with waterproof mattress covers or protectors. High heat can:

  • Melt or crack the waterproof membrane
  • Cause bubbling, peeling, or stiff patches
  • Reduce the cover’s water-resistant performance

If the label says “line dry,” “air dry only,” or “no tumble dry,” avoid the dryer completely. Using the dryer anyway may save time once, but can shorten the life of the cover.

How Should You Dry a Waterproof Mattress Cover?

Waterproof covers usually have a plastic-like or rubbery backing that protects your mattress from spills and accidents. This layer is especially sensitive to heat.

Best practice for waterproof covers:

  • Air dry flat or on a line whenever possible
  • If the label allows tumble drying, use:
    • Low heat only
    • Short cycles, checking frequently
    • Remove promptly to prevent overheating

If you are unsure and the label is missing or faded, treat it like a delicate item and air dry it to be safe.

What If There’s No Care Label?

Sometimes mattress covers lose their tags over time. In that case, the answer to “Can you dry a mattress cover?” depends on what you can see and feel:

  • Feels like plain fabric only (no backing)?
    Likely safe for low or medium heat in the dryer.
  • Has a shiny, rubbery, or plastic back?
    Dry on low heat or air-dry only.
  • Heavily padded or quilted?
    Use low heat and extra time or air dry to avoid clumping.

When in doubt, err on the side of low heat and air drying. It may take longer, but it reduces the risk of damage.

How Long Does It Take to Dry a Mattress Cover?

Drying time depends on thickness and method:

  • Thin cotton/poly covers: often 30–60 minutes in a dryer on low or medium
  • Quilted or padded covers: may need 60+ minutes and occasional fluffing
  • Air drying: can range from a few hours to overnight, depending on airflow and humidity

🌬️ Tip: To speed up air drying, hang the cover where air can circulate on both sides, and gently stretch it to flatten any folds.

Common Drying Mistakes to Avoid

Here are frequent issues people run into when deciding if they can dry a mattress cover:

  • Using high heat on waterproof or elastic parts, causing warping or melting
  • Overloading the dryer, so the cover stays damp in folds or corners
  • Leaving it bunched up to dry, which can cause musty smells
  • Not fully drying the cover before putting it back on the bed, trapping moisture against the mattress
