How To Clean a Leesa Mattress: Simple Steps and FAQs

If you’re searching for How To Clean a Leesa Mattress, you’re likely dealing with spills, stains, or just everyday buildup and want to care for your mattress properly. This guide walks through safe, practical steps to clean and freshen a foam-style mattress without damaging the materials.

What should I know before I clean a Leesa-style mattress?

Foam mattresses typically use layers of foam with a non-removable fabric cover on some models and a zippered cover on others. Even when there is a zipper, the outer layer is often not designed for machine washing or harsh chemicals, as this can damage the fabric, affect the feel, or impact long-term durability.

Before you begin, check:

Any care tag or label on the mattress
Whether the cover is removable or sewn on
Recommended cleaning methods for foam and fabric

In general, it’s safest to use spot cleaning, mild cleaners, and minimal moisture.

How To Clean a Leesa Mattress after a spill

When a spill happens, acting quickly can limit staining and odors.

1. Blot, don’t rub

Use a clean, dry cloth or paper towels to blot up as much liquid as possible. Press gently but firmly.

Do not scrub, as this can push the liquid deeper into the foam.
Work from the outside of the spill toward the center to avoid spreading it.

2. Use a mild cleaning solution

For many spills (like drinks or mild food stains), a gentle solution is enough:

Mix a small amount of mild liquid detergent with cool water.
Lightly dampen a clean cloth with the solution (not soaking wet).
Blot the stained area, lifting rather than rubbing.

Avoid bleach, strong solvents, or anything highly abrasive. These can fade fabric or break down foam.

3. Rinse with a damp cloth

Use another cloth lightly moistened with plain water to blot away any soap residue. Again, avoid soaking the mattress. Too much water can be slow to dry and may cause lingering odors.

4. Let it air dry completely

Allow the mattress to air dry in a well-ventilated room. If possible:

Open windows or use a fan to speed airflow.
Avoid placing the mattress in direct, intense sunlight for long periods, which can sometimes weaken materials.

Only remake the bed when the area feels fully dry to the touch.

How do I remove stains or odors from a Leesa-style mattress?

Stains and odors are common concerns when people look up How To Clean a Leesa Mattress. A gentle, dry approach often works well.

Using baking soda for freshness

Baking soda is frequently used to absorb odors and surface moisture:

Sprinkle a light layer of baking soda over the affected area (or the whole surface for general freshening).
Leave it for several hours, or ideally overnight.
Vacuum thoroughly using a hand attachment.

This method is non-invasive and can be repeated as needed.

Spot treating tougher stains

For more stubborn marks:

Create a mild mixture of water and a small amount of detergent.
Lightly apply with a cloth and dab only on the stained area.
Follow with a clean, damp cloth to remove residue.
Allow plenty of time to air dry.

If you’re dealing with organic stains (such as food or drink), a gentle, enzyme-based cleaner labeled as safe for fabrics and upholstery is sometimes used by consumers. Test a small, hidden area first to check for discoloration.

Can I remove and machine wash the mattress cover?

Even if your mattress has a zippered cover, that does not always mean it is machine washable. Washing in hot water or using high heat in a dryer can shrink or weaken the cover, or affect how it fits the foam core.

When considering How To Clean a Leesa Mattress cover, keep these points in mind:

Check the care tag for any printed instructions.
If machine washing is not specified as safe, treat the cover as “spot clean only.”
If you do remove the cover, avoid exposing the bare foam to excessive moisture or direct cleaning products.

In many cases, manufacturers intend the cover to stay on the mattress at all times, with surface spot cleaning as the primary method of care.

How can I keep my mattress clean in the future?

Preventive care is often the easiest way to avoid deep cleaning later.

Common protective steps include:

Using a water-resistant mattress protector
Washing sheets and bedding regularly
Addressing spills immediately rather than letting them sit
Vacuuming the surface occasionally with a clean upholstery attachment

These habits can help limit stains, dust, and odors over time.

Is there anything I should never do when cleaning?

To protect foam and fabric, it’s generally wise to avoid:

Soaking the mattress with water or cleaner
Using bleach or harsh chemicals directly on the surface
Steam cleaning or very high heat on the foam
Scrubbing aggressively, which can damage fibers and push stains deeper

Gentle, minimal-moisture methods help maintain the mattress’s feel and appearance.
