To stop a new mattress from smelling, unwrap it completely, place it flat in a well ventilated room with windows open and a fan running, and let it air for 24 to 72 hours. That chemical or sweet plastic odor is off-gassing from foam, adhesives and tight packaging, and it fades fastest with steady airflow and time, not with perfumes.
You do not need to tolerate the smell for weeks or use harsh chemicals to cover it. Below you will find how to ventilate correctly, how to use baking soda and natural absorbers safely, and how to tell when the odor is normal and when it needs more attention. Pairing your new bed with breathable bedding, like the best sheets for hot sleepers, also helps air circulate and keeps odors from getting trapped.
How to Get Rid of New Mattress Smell Fast
1. Unwrap and Ventilate for 24 to 72 Hours
Remove all plastic, cardboard and wrapping immediately after delivery and place the mattress flat on its foundation or platform. Keep it uncovered with no protector, topper or sheets so VOCs can escape freely from the surface and sides. Open windows on opposite sides of the room if possible and run a ceiling fan or portable fan to create cross ventilation.
Airflow matters more than just waiting. Keep the bedroom door open, avoid placing the mattress against a wall that blocks air, and ventilate for several hours at a stretch over two to three days. Most people notice the sharpest drop in odor after the first day, with a steady fade after that.
2. Sprinkle Baking Soda and Vacuum Thoroughly
After the first 6 to 8 hours of airing, lightly dust the entire top surface with baking soda. This natural absorber traps odor molecules without adding fragrance or moisture to the foam. Let it sit for 8 hours or overnight while you continue to ventilate the room, then vacuum thoroughly with an upholstery attachment.
Repeat on the other side if your design allows and if a faint smell remains, but avoid soaking the mattress with liquids at this stage. Moisture can get trapped inside foam layers and actually slow off-gassing. A breathable base and cover system, similar to what you find with best bamboo mattress options, helps prevent future odor buildup as well.
3. Control Temperature, Humidity and Sunlight Carefully
Warm, slightly dry air helps VOCs dissipate more quickly, so aim for a room temperature around 68 to 72 degrees and humidity below 50 percent if you can manage it. A dehumidifier or air conditioner helps in humid climates, and an hour of gentle, indirect sunlight near a window can freshen the surface without overheating it.
Do not place memory foam in direct hot sun for hours or aim a space heater directly at it, as excessive heat can damage foam and adhesives. Maintain steady, moderate airflow instead and wait to add a mattress protector until the initial odor has faded. This is the same gentle care recommended for best latex mattress models that also need to breathe.
4. Keep Bedding Off Until the Odor Fades and Freshen Naturally
Resist the urge to make the bed right away. Sheets, blankets and waterproof covers trap gases underneath and keep you breathing them longer. Let the bare mattress breathe for at least a full day, then add clean, breathable cotton or linen sheets once the smell is faint and only noticeable up close.
If you want a light scent after vacuuming off the baking soda, use a plant based fabric refresher sparingly and spray from a distance so the surface does not get damp. Heavy perfumes, scented candles and incense only mask the issue and can irritate sensitive noses. Patience plus consistent ventilation clears the smell far more effectively than any cover up.
5. Add Charcoal Bags or an Air Purifier for Persistent Odors
For small apartments, winter weather or extra sensitivity to smells, place activated charcoal bags near the bed or run a HEPA purifier with a carbon filter in the room. Both absorb airborne VOCs without introducing chemicals directly to your mattress. Keep them a few feet away so air can still circulate around all sides of the bed.
Recharge charcoal bags in sunlight as directed and run the purifier on low continuously for the first week. This combination is especially helpful when you cannot keep windows open for long periods. It supports ventilation while you wait for the foam to finish its initial off-gassing phase.

The GEODE Mattress Cleaner and Deodorizer is a 32 fl oz enzyme based spray designed to clean and refresh fabric surfaces, primarily mattresses. It is ideal for families with young children, pet owners, and anyone dealing with sweat, spills or lingering odors who prefers a plant derived, non-toxic solution.
Its standout feature is the natural enzyme formula that targets organic matter to break down stains and neutralize odors rather than covering them up. In real world use, many customers report impressive results on both fresh accidents and older mysterious stains, plus complete removal of sour smells, while leaving a soft sweet lavender freshness.
The bottle is a practical spray format measuring 2.5 x 4.5 x 9 inches, easy to store and handle for spot treatments. The formula is eco-friendly and safe for all fabrics, so you can confidently use it on mattresses, upholstery and carpets without worrying about harsh residues or discoloration.
Performance is not uniform for every stain type, and a few users found that heavily set stains remained after an overnight soak. The lavender scent is generally described as pleasant and light, but fragrance sensitive users should test in a ventilated area, and you will need to allow several hours for the enzymes to work.
Overall, GEODE delivers a compelling balance of effective cleaning, odor elimination and gentle, non-toxic care for your home. If you want a fabric safe deodorizer that actually addresses the source of odors and leaves a fresh natural scent, this is a strong choice worth trying.

SilverWorks Fabric Spray Odor Eliminator is a natural, silver ion powered deodorizer made for fabrics throughout the home. It is ideal for anyone battling musty closets, pet odors, or stale smells in clothing, bedding, couches and upholstery that cannot be easily laundered.
Its standout feature is the silver ion technology that neutralizes odor causing compounds rather than masking them with perfume. In real world use, it consistently refreshes everything from daily clothing to luggage and bedding, even tackling deeply embedded odors that other sprays only temporarily cover.
Design and build quality are simple but effective, with a 16.9oz bottle and a fine mist sprayer that delivers an even, steam like application. The spray distributes lightly and evenly, helps avoid spotting, and the bottle is sized for regular use without feeling bulky or awkward to handle.
There are a few drawbacks to consider. For best results you need to saturate the fabric more than a light spritz, and the brand recommends testing on a hidden area first. The mild, clean scent is pleasant but subtle, so users expecting a strong, long lasting fragrance may find it too light.
Overall, SilverWorks offers a powerful yet natural alternative to traditional fabric refreshers. If you want a versatile, perfume free solution that actually eliminates odors and leaves fabrics truly fresh, it is an excellent choice for everyday home use.

In real world use, it stands out for its light, clean scent that freshens without overwhelming the space. Users report spraying drapes, rugs, bedding, and even dirty laundry areas with freshness that lingers for days while actually eliminating odors rather than covering them.

The Vergali Activated Charcoal Odor Absorber is a 10-pack of bamboo charcoal bags designed to naturally eliminate strong odors throughout the home and car. It is ideal for anyone seeking a fragrance-free, chemical-free alternative to sprays and plug-ins, especially families with pets, kids or allergy sensitivities.
In real-world use, these bags excel at gradually absorbing persistent odors from shoes, closets, basements and vehicles rather than masking them.

Each bag is compact and neatly sewn in a breathable linen pouch that looks discreet in any space. At 4 x 1.2 x 5.5 inches and a combined weight that feels substantial, the build feels durable and mess-free with no powders or residues to worry about.

Place one or two bags in any enclosed space where odors occur, such as closets, shoe cabinets, cars, basements or near pet areas. For larger rooms or strong odors, use multiple bags for faster and more complete absorption.
Allow the bags to work undisturbed for several hours to gradually trap odors and moisture. Unlike sprays, they purify the air without any fragrance, so freshness builds naturally over time.
Rejuvenate the bags once a month by placing them in direct sunlight for 1 to 2 hours. This releases trapped pollutants and restores the charcoal's porous structure for continued use for up to two years.
Pros
- Effectively neutralizes lingering pet and household odors
- Safe for use around pets with simple ingredients
- Pleasant, subtle scent that is not overwhelming
- Leaves no residue and vacuums up easily
- A little product goes a long way for great value
Cons
- Scent is subtle and fades relatively quickly, does not last all day
- Pouch packaging makes it difficult to sprinkle evenly
- Scoop is buried deep in the powder and hard to find initially
The Good Natured Brand Carpet Deodorizer and Air Freshener Powder is a 31 ounce odor eliminator designed for homes with pets, kids, and high traffic carpets. It is ideal for pet owners who need to tackle lingering dog odors without harsh chemicals or overwhelming perfumes.
In real world use, the powder excels at neutralizing odors rather than just masking them, leaving carpets smelling subtly fresh after a 10 to 20 minute treatment. Users consistently praise its light lavender and lemon eucalyptus scents, which freshen rooms without being overpowering and vacuum up completely.
The formula is made with simple, pet safe ingredients and relies on a baking soda base to absorb odors effectively. The generous 31 ounce pouch provides excellent coverage, as only a light sprinkle is needed to treat large areas, offering multiple uses from a single bag.
There are a few practical drawbacks to consider before buying. The fragrance, while pleasant, tends to fade within hours, and the pouch design makes even sprinkling difficult without transferring the powder to a shaker. The included scoop is also buried deep in the powder and can be hard to locate at first.
Overall, this deodorizer is a strong value for anyone seeking a natural, residue free solution for pet odors and everyday carpet freshness. If you want a subtle, clean scent and a safe formula that actually reduces odors, this is an excellent and reliable choice.
These odor solutions complement ventilation rather than replacing it. Enzyme cleaners refresh the surface after airing, fabric sprays add a light natural scent once baking soda is vacuumed away, and charcoal bags plus deodorizing powders absorb lingering VOCs while your mattress finishes off-gassing.
When This Won’t Fix It
If the smell stays sharp and chemical after two weeks of consistent ventilation, or you notice persistent eye or throat irritation, headaches, or visible mold, mildew or stains, airing alone will not solve it. Contact the manufacturer about a defect or return option and consult a professional for indoor air quality concerns or persistent symptoms.
Frequently Asked Questions
How long does new mattress smell last?
Most new mattress odor fades within 24 to 72 hours, with faint traces lasting up to a week for dense memory foam. Keeping windows open, using fans, and vacuuming baking soda after an overnight treatment speeds the process. If you are sensitive to smells, look for low VOC certified models like many featured in our guide to the best king mattress for 2026.
Is new mattress smell harmful to sleep on?
For most people the odor is unpleasant but not dangerous at low levels and it dissipates quickly with ventilation. If you are pregnant, have asthma or chemical sensitivities, air the mattress in a separate well ventilated room for several days before sleeping on it. If irritation persists, move to another room and talk with your healthcare provider.
Can I use Febreze or vinegar on a new mattress?
You can use a light, fabric safe spray after the initial airing and baking soda treatment, but avoid soaking the foam with vinegar or heavy fragrance. Vinegar leaves its own strong odor and excess moisture, while heavy sprays only mask VOCs temporarily. Stick to dry methods first, then add a light mist only once the mattress is nearly odor free.
