How To Get Rid Of Smell From New Mattress: Simple Tips That Work

If you’ve just unboxed a bed and are wondering how to get rid of smell from new mattress, you’re not alone. Many new mattresses have a noticeable “factory” or “new foam” odor in the first few days. This FAQ-style guide explains what that smell is, whether it’s normal, and practical steps to reduce it as quickly and safely as possible.

Why Does My New Mattress Smell?

What causes the “new mattress” odor?

Most new mattress smells come from:

  • Off-gassing: When materials like foam or adhesives release trapped manufacturing odors after being unwrapped.
  • Packaging: Mattresses are often compressed and sealed in plastic, so odors build up until you open them.
  • Storage and transport: A mattress may pick up a slight warehouse or packaging scent before it reaches your home.

This is especially common with foam and hybrid mattresses, but even some innerspring models can have a mild scent at first.

Is the smell from a new mattress normal?

A light to moderate “new” smell is very common and usually fades on its own over several days. Many sleepers notice the odor most during the first 24–72 hours, then it gradually becomes less noticeable.

If the smell is extremely strong, irritating, or lasts much longer than expected, it may be worth contacting the manufacturer for guidance.

How To Get Rid Of Smell From New Mattress: Step-by-Step

1. Air it out in a well-ventilated room

This is the most effective and important step.

  • Remove all plastic and packaging as soon as you can.
  • Place the mattress in a well-ventilated room with windows open.
  • If possible, run a fan to move air across the mattress and out of the room.

Allowing fresh air to circulate helps odors disperse faster.

2. Let it “breathe” before making the bed

It’s tempting to put sheets on right away, but fabrics can trap odors.

  • Leave the mattress uncovered for several hours, or even a full day, before adding bedding.
  • When you do make the bed, consider using breathable cotton sheets to allow airflow.

3. Use baking soda to absorb odors

Baking soda is a common household deodorizer.

  • Lightly sprinkle baking soda over the entire surface of the mattress.
  • Let it sit for a few hours, or longer if the smell is strong.
  • Vacuum thoroughly using a clean upholstery attachment.

You can repeat this process if needed. Avoid using wet sprays or soaking the mattress, as moisture can cause other issues.

4. Improve room airflow and circulation

Along with open windows and fans, you can:

  • Keep doors open to allow cross-ventilation.
  • Use a standing or box fan to direct air out a window.
  • If the room has one, run an exhaust fan to pull air out.

Consistent airflow is key to reducing odor over time.

Is It Safe To Sleep On a New Mattress That Smells?

Many people wonder if they should wait before sleeping on a new mattress.

  • If the smell is mild and does not bother you, some sleepers choose to use the mattress right away.
  • If the odor is strong or unpleasant, you may want to let it air out for at least a day or two before sleeping on it for long periods.

Anyone who finds the smell especially irritating may prefer to ventilate the mattress longer and spend less time in the room until the odor fades.

What Should I Avoid When Deodorizing a New Mattress?

Some methods can do more harm than good.

Avoid:

  • Strong chemical sprays or perfumes directly on the mattress
    These can add more odor and may be difficult to remove.
  • Soaking the mattress with water or cleaners
    Excess moisture can lead to damage or unwanted smells.
  • Covering the mattress immediately with thick protectors
    This can trap odors inside and slow down off-gassing.

Instead, focus on airflow, time, and gentle odor absorbers like baking soda.

How Long Does the New Mattress Smell Last?

The timeline can vary depending on materials and ventilation:

  • Some mattresses lose most of their odor in a few days.
  • Others may have a faint scent that lingers for a couple of weeks but becomes less noticeable over time.

If you’ve tried ventilating, using baking soda, and ensuring good airflow and the smell remains very strong for an extended period, you may want to ask the manufacturer for more specific guidance.
