How To Get Rid Of New Mattress Odor: Simple Steps That Actually Help

If you’ve just unboxed a mattress and noticed a strong “new mattress smell,” you’re not alone. Many people search for “How To Get Rid Of New Mattress Odor” because they want to know if the smell is normal, how long it lasts, and what they can safely do to reduce it.

This guide explains what that odor is, why it happens, and the most practical ways to air out and care for your new bed.

What Is “New Mattress Odor” and Is It Normal?

Many new mattresses have a noticeable smell when first removed from their packaging. This is especially common with models that arrive compressed and vacuum-sealed.

What causes the smell?

  • Packaging being opened for the first time
  • Foams and fabrics releasing trapped odors from manufacturing
  • Adhesives, textiles, or protective coatings “off-gassing” into the air

For most people, this odor is temporary and gradually fades as the mattress is exposed to fresh air.

How To Get Rid Of New Mattress Odor Fast

If your main question is how to get rid of new mattress odor, the key is to increase airflow and time out of the packaging.

1. Let the Mattress Breathe

  • Remove all plastic wrapping as soon as possible.
  • Place the mattress in a well-ventilated room, ideally with windows open.
  • Use a fan to keep air moving around and above the mattress surface.

Many sleepers find that the strongest odor fades within a few days when the bed is properly aired out.

2. Use Natural Deodorizers (If Desired)

Some people prefer to simply wait it out, while others like to use gentle odor-absorbing methods, such as:

  • Lightly sprinkling baking soda over the surface, letting it sit for several hours, then vacuuming it up
  • Placing bowls of baking soda or plain charcoal in the room (on nearby furniture, not directly on the mattress unless contained)

These methods help absorb lingering smells without adding heavy fragrances.

3. Keep Bedding Simple at First

During the first few days:

  • Use light, breathable sheets and minimal bedding.
  • Avoid thick mattress toppers or multiple layers, which can trap odor longer.

This allows the mattress surface to release smells more efficiently.

How Long Does New Mattress Smell Last?

There is no exact timeline that applies to every mattress, but many users report that:

  • The strongest odor is usually in the first 24–72 hours.
  • A faint smell may remain for a few days or longer, especially in small or poorly ventilated rooms.

If you can, allow the mattress to air out before sleeping on it overnight, especially if you find the smell unpleasant.

Is New Mattress Odor Harmful?

Most people experience new mattress odor as annoying rather than harmful. It can be similar to the smell of a new car, new paint, or new furniture.

However, sensitivity varies:

  • Some people are more bothered by strong smells than others.
  • Those who are sensitive to odors may prefer to let the mattress air out for a longer period before use.

If the smell feels overwhelming or you are worried about how you’re reacting to it, it may be helpful to spend less time in the room while the mattress is airing out and consider increasing ventilation as much as possible.

When Should You Be Concerned About New Mattress Odor?

While most new mattress smells gradually fade, you may want to pay closer attention if:

  • The odor is extremely strong even after several days of airing out
  • The smell seems to intensify instead of fading
  • You notice an unusual or “chemical” smell that doesn’t improve with ventilation

In these cases, many consumers choose to keep the mattress in a separate, well-ventilated area until the odor lessens or to seek further guidance from the seller.
