How To Clean Leesa Mattress: Step‑by‑Step Care Guide

If you’re searching for “How To Clean Leesa Mattress”, you’re likely dealing with spills, stains, or everyday buildup and want to keep your mattress fresh without damaging it. This FAQ-style guide walks through safe, practical steps to clean and maintain a Leesa-style foam mattress at home.

What should I know before cleaning a Leesa mattress?

Leesa mattresses are typically made with foam layers and a zippered fabric cover. That makes them comfortable, but it also means you need to use gentle products, minimal moisture, and no harsh chemicals.

Key things to keep in mind:

  • The foam core should never be soaked or saturated with water.
  • Strong cleaners, bleach, and solvents can damage foam and fabric.
  • Many covers are not designed for machine washing, even if they have a zipper.

Always check any tags or care instructions that came with your mattress, and when in doubt, treat it like a standard modern foam mattress: spot clean only, with mild solutions.

How To Clean Leesa Mattress: What is the safest basic cleaning method?

For routine cleaning and small messes, focus on surface care and spot cleaning.

Step-by-step surface clean

  1. Strip the bed
    Remove sheets, protectors, and any toppers.

  2. Vacuum the mattress

    • Use a hand vacuum or upholstery attachment.
    • Gently vacuum the top and sides to remove dust, pet hair, and crumbs.
    • Avoid pressing too hard to keep from tearing or stretching the cover.

  3. Spot clean stains

    • Mix a small amount of mild liquid soap with cool water.
    • Lightly dampen a clean cloth (do not soak it).
    • Blot the stain, starting from the outside and working inward.
    • Follow with a second cloth dampened with plain water to wipe off soap residue.
    • Blot dry with a dry towel.

  4. Air dry completely

    • Allow the mattress to dry in a well-ventilated room.
    • Avoid sleeping directly on it until the cleaned area is fully dry to the touch.

This gentle process usually works for sweat marks, light spills, and surface dirt without harming foam layers.

Can I remove and wash the Leesa mattress cover?

Even with a zippered case, most foam mattress covers are not meant for machine washing. Washing can:

  • Shrink or distort the fabric
  • Damage zipper seams
  • Affect how the cover fits the foam

If your cover is removable, it is often intended for access, not for laundry. The safer approach is to:

  • Leave the cover on the foam
  • Spot clean only, rather than removing and immersing it in water or placing it in a washing machine

If a spill soaks through the cover, focus on carefully blotting and air-drying rather than pulling the entire cover off and washing it like bedding.

How do I handle spills, stains, and odors?

What if I spill liquid on the mattress?

  1. Act fast

    • Immediately place clean, dry towels on the spill.
    • Press down to absorb as much liquid as possible.
    • Avoid rubbing, which can push liquid deeper into the foam.

  2. Lightly clean the area

    • Use a mild soap-and-water solution on a cloth.
    • Blot the surface gently; don’t pour liquid directly onto the mattress.

  3. Dry thoroughly

    • Use fresh dry towels to absorb remaining moisture.
    • Let it air dry fully; point a fan at the area if needed.

How to treat common stains?

  • Sweat or body oils: Mild soap and cool water, blotting only.
  • Food or drink stains: Same method, with extra blotting and patience.
  • More persistent marks: Multiple gentle cleaning sessions are usually better than one aggressive attempt.

What about mattress odors?

For general odor control:

  • Lightly sprinkle baking soda over the dry mattress surface.
  • Let it sit for several hours (or a full day if possible).
  • Vacuum thoroughly to remove the baking soda and trapped odors.

Avoid heavy perfumes or sprays that saturate the fabric; they may mask smells instead of helping them dissipate.

How often should I clean a Leesa mattress?

You do not need to deep clean frequently, but regular light maintenance helps:

  • Every 1–3 months

    • Vacuum the mattress surface.
    • Air out the mattress by leaving it uncovered for a few hours.

  • After any spill or accident

    • Address immediately with blotting and spot cleaning.

Using a washable mattress protector over your mattress can significantly reduce how often you need to clean the mattress itself.

What should I avoid when cleaning a Leesa mattress?

To keep the foam and cover in good condition, avoid:

  • Bleach or harsh chemicals
  • Steam cleaners or carpet cleaners on the mattress
  • Soaking or saturating any part of the mattress with water
  • Scrubbing aggressively with stiff brushes
  • Placing the mattress in direct, intense heat, such as outdoors in very strong sun for long periods

Foam materials respond best to gentle, minimal-moisture cleaning.
