How To Clean a Sleep Number Mattress: Simple Steps and FAQs

If you’re wondering how to clean a Sleep Number mattress without damaging the air chambers, electronics, or cover, you’re not alone. These adjustable beds have a different design from traditional mattresses, so it helps to know what’s safe, what to avoid, and how to handle spills, stains, and routine care.

Below you’ll find clear answers to the most common questions about how to clean a Sleep Number mattress in a safe, practical way.

What makes cleaning a Sleep Number–style mattress different?

Unlike an all-foam or innerspring mattress, this type of mattress typically includes:

  • Air chambers and internal components
  • A zippered mattress cover or top panel
  • Electronics or hoses connected to a pump

Because of this construction, excess moisture and harsh chemicals can be risky. The key is surface-level cleaning with gentle products and light moisture, rather than soaking or steam-cleaning the mattress.

How To Clean a Sleep Number Mattress: Basic Routine Care

How should I do regular cleaning and maintenance?

For general upkeep, focus on surface freshness and dust reduction:

  • Vacuum the surface
    Use a vacuum with an upholstery attachment to gently remove dust, crumbs, and hair from the top and sides. This can be done every month or so, or whenever needed.

  • Spot clean only
    Clean small marks or stains rather than trying to wash the entire surface.

  • Air out the mattress
    When changing sheets, let the mattress air out for a few minutes to reduce trapped odors and moisture.

How do I spot clean stains safely?

What’s the best way to remove stains?

To spot clean, you can generally use a mild detergent mixed with water:

  1. Prepare a gentle solution
    Mix a small amount of mild liquid detergent with cool or lukewarm water. Avoid bleach or strong solvents.

  2. Dampen a clean cloth
    Lightly dampen (do not soak) a white cloth or sponge with the soapy solution.

  3. Blot the stain
    Gently blot the stained area. Avoid scrubbing hard, as it can damage the fabric or push liquid deeper into the mattress.

  4. Rinse with a clean damp cloth
    Use another cloth with plain water to blot and remove any soap residue.

  5. Dry thoroughly
    Blot with a dry towel and let the area air dry completely before putting sheets back on. Fans and open windows can help speed up drying.

What if I spill liquid on my Sleep Number mattress?

How should I handle spills right away?

When liquids are involved, speed and minimal moisture are crucial:

  • Act immediately
    Blot up as much liquid as possible with dry, absorbent towels. Press firmly, but avoid rubbing.

  • Remove bedding
    Take off sheets and any protectors so the spill doesn’t spread or stay trapped.

  • Check if the top cover is removable
    If there is a zippered top panel that’s washable per the care tag, follow those instructions. Keep water away from internal air chambers, foam, and electronics.

  • Use only light spot cleaning
    After absorbing the spill, follow the gentle spot-cleaning steps with minimal moisture.

  • Ensure complete drying
    Allow extra time for the area to dry thoroughly. Do not close up any zippers or re-make the bed until there is no dampness left.

Can I use a mattress protector or cover?

Is a protector recommended?

Many sleepers choose a separate, washable mattress protector to make routine care easier. A protector can help:

  • Reduce direct contact with sweat, body oils, and spills
  • Limit the need for deep, difficult cleaning of the mattress surface
  • Keep the mattress looking and smelling fresher over time

Check that any protector you use fits well and doesn’t interfere with the mattress’s adjustability or the feel you prefer.

What products should I avoid when cleaning?

To keep your mattress in good condition, avoid:

  • Bleach or harsh chemicals – These can weaken or discolor the fabric.
  • Strong solvents – May damage materials or leave strong odors.
  • Steam cleaners – Introduce high heat and moisture into internal components.
  • Overly wet cleaning methods – Soaking fabrics or letting liquids pool can affect foam, air chambers, or electronics.

When in doubt, less is more: light moisture, mild soap, and gentle blotting are usually safest.

How often should I clean a Sleep Number–style mattress?

Frequency depends on use and personal preference, but a simple guideline is:

  • Vacuuming: About once a month, or as needed
  • Spot cleaning: Whenever you notice stains or accidents
  • Bedding changes and airing out: Regularly, based on your usual laundry routine

Consistent light maintenance is usually easier and more effective than trying to fix heavy buildup later.
