Can I Wash Leesa Mattress Cover? Care, Cleaning, and What to Avoid

If you’re asking “Can I wash Leesa mattress cover?”, you’re likely dealing with a spill, stain, or just general refresh. Mattress covers can be confusing, especially when some look washable but actually aren’t designed for the washing machine.

This FAQ walks through what “washing” typically means for a mattress cover, what’s usually safe, and how to keep a foam mattress and its cover clean without damage.

Can I Wash Leesa Mattress Cover in the Washing Machine?

For most foam-style mattresses with a zippered cover, including models similar to Leesa, the outer cover is usually not designed for machine washing, even if it zips off.

Machine washing can:

  • Stretch or shrink the fabric
  • Damage the zipper or seams
  • Compromise the fire-retardant barrier or inner layers
  • Lead to wrinkling or bunching that affects how the cover fits afterward

Because of this, the safest assumption is that the cover should not be machine washed or fully submerged in water, unless the specific care label on your cover clearly says otherwise.

📝 Key tip: Always check the small fabric care tag attached to the cover. That tag overrides general guidance.

If I Can’t Machine Wash It, How Do I Clean the Cover?

Most mattress covers, including those on foam mattresses, are intended to be spot cleaned only.

Basic spot-cleaning steps

  1. Remove bedding and protect the foam
    Unzip the cover only if needed to access the stained area, but avoid removing it completely if the instructions say not to. Do not expose foam to heavy moisture.

  2. Blot, don’t rub

    • Use a clean, dry cloth to blot any fresh spills.
    • Avoid pressing liquid deeper into the fabric.

  3. Use mild cleaning solution
    A simple option is:

    • Cool or lukewarm water
    • A small amount of mild liquid detergent
    • Gently dab the solution onto the stained area with a cloth.

  4. Rinse with a damp cloth
    Wipe the area with a cloth lightly dampened with plain water to remove detergent residue.

  5. Air dry thoroughly

    • Let the cover dry completely before putting bedding back on.
    • Avoid direct heat sources like hairdryers or heaters, which may affect the fabric or foam.

Why Does It Matter How I Wash the Cover?

When wondering “Can I wash Leesa mattress cover?”, the hidden concern is often: Will washing it ruin the mattress?

Improper washing can:

  • Void certain coverage terms in typical product policies or warranties
  • Cause premature wear and tear on fabric and zippers
  • Let moisture seep into the foam, which can lead to odors or long drying times

Keeping water and harsh chemicals away from the foam core is one of the most important care rules.

Can I Remove the Cover Completely?

Many foam mattresses have a zipper to help with spot cleaning, not necessarily for full removal and machine washing.

If you do unzip:

  • Avoid pulling or forcing the zipper around corners.
  • Keep the foam protected from spills or liquid cleaners.
  • Only remove as much of the cover as you need for cleaning.

Unless the care label clearly states that full removal and machine washing are allowed, treat the zipper as an access point—not an invitation to launder the whole cover.

What About Deep Cleaning or Odor Removal?

If you’re not machine washing the cover, you can still freshen it:

  • Vacuum the surface gently using a clean upholstery attachment to remove dust and crumbs.
  • Lightly sprinkle baking soda over the surface of the mattress (with the cover on), leave it for several hours, then vacuum it up.
  • Regularly rotate the mattress (if the design allows) so that wear and minor impressions are more evenly distributed over time.

Avoid:

  • Soaking the cover
  • Using strong chemical cleaners or bleach
  • Steam cleaning the foam or cover, unless the product care instructions explicitly allow it

Should I Use a Separate Mattress Protector?

Because most mattress covers are not meant to be frequently washed, many sleepers choose a removable, machine-washable mattress protector to act as a barrier between sheets and the mattress.

A protector can help with:

  • Spill and stain resistance
  • Easier laundering (protector goes in the wash, mattress cover does not)
  • Keeping dust and debris off the mattress surface
