What Is Mattress Off Gassing and How Do You Stop It?

That "new mattress smell" everyone talks about? It's a real thing, and as a third-generation, family-owned furniture expert serving Succasunna, NJ for over 70 years, we've heard just about every question there is on the topic. It's that distinct, almost chemical-like odor that comes with a brand-new mattress, and it has a name: mattress off-gassing.

For over 70 years, our family at Suburban Furniture has been a part of the local community here in Succasunna, Roxbury Township, and across Morris County. We believe in being a trustworthy, neighborly resource, and that means being honest about what you're bringing into your home.

At its core, off-gassing is just the release of leftover airborne chemicals from the manufacturing process. These are called Volatile Organic Compounds (VOCs), and they've been trapped inside the mattress materials, waiting to escape.

What Is Mattress Off Gassing?

Simply put, mattress off-gassing is the process where chemicals used in manufacturing—especially in synthetic foams—are released into the air as gases at room temperature. This is most noticeable with bed-in-a-box mattresses. Since they’re compressed and sealed in plastic, all those gases are trapped until you unwrap the mattress in your bedroom.

As a third-generation furniture family right here in Northern New Jersey, we feel our neighbors in Roxbury Township and Morris County deserve to know exactly what they’re bringing into their homes. Unlike a faceless online seller, we’re right here to give you real answers and guide you toward a healthier night's sleep.

This diagram breaks it down perfectly, showing how the mattress materials create the VOCs that you eventually smell.

It all starts with the materials. The stuff your mattress is made of is the source of that "new" smell.

What materials cause off-gassing?

The main source is almost always the synthetic materials packed into modern mattresses, especially polyurethane foams like memory foam. That familiar smell comes from the release of VOCs from these materials and the adhesives used to bind layers together. The odor can stick around for a few days or even weeks.

Interestingly, according to the Sleep Foundation's research on off-gassing, synthetic foams are a major contributor. Memory foam, first developed by NASA in the 1960s, is made with petroleum-based chemicals that happen to turn into gas at room temperature.

This is a huge differentiator between mattress types, and it’s something you can investigate for yourself right here in our Succasunna showroom. To help you know what to look for, we've put together a quick breakdown of common materials.

Common Materials and Their Off-Gassing Potential

This table breaks down which mattress materials are most likely to off-gas, helping you understand what to look for when shopping.

Ultimately, understanding these components is the first real step toward picking a mattress you can feel good about. Our promise as a local business is to give our neighbors in Sussex County and beyond the transparent, expert advice you just won’t find at a big-box store or from an online chatbot.

What's Actually Causing That New Mattress Smell?

That "new mattress smell" comes from Volatile Organic Compounds (VOCs) breaking down at room temperature and turning into a gas, which then floats into the air. A lot of modern mattresses, especially ones with memory foam or polyurethane foam, are built with these compounds. It’s the same reason you get that “new car smell”—it’s the natural release of chemicals from plastics, vinyls, and foams.

The science behind it is pretty straightforward. These compounds aren't perfectly stable when they’re just sitting at room temperature in your Northern New Jersey home. Over time, they break down and transform into a gas, which then floats out into the air in your room.

Why does the packaging make the smell worse?

The smell is often more intense because the mattress has been vacuum-sealed in plastic, trapping every single VOC inside with no way to escape. This is particularly true for those popular bed-in-a-box mattresses you see everywhere online.

During manufacturing, these mattresses get squished, rolled up tight, and then sealed. The second you slice open that plastic in your Roxbury Township or Morris County home, you get a powerful, concentrated burst of all those trapped gases at once. It’s just like opening a soda bottle that’s been shaken up—all that built-up pressure creates a sudden rush.

This is a huge reason why buying from a trusted local store like Suburban Furniture can make such a difference. Many of the mattresses we carry are delivered to our Succasunna showroom fully expanded, giving them plenty of time to air out before they ever get to your bedroom. Understanding the basics of mattress construction is key to making an informed choice.

Unlike online-only sellers who just ship a box and call it a day, our “Real Person Support” team can show you the materials in person. We've been helping our Northern New Jersey neighbors for over 70 years, and offering expert, honest advice is a huge part of our commitment. We'll help you understand what's inside your mattress and point you toward lower-VOC options that give your family true peace of mind.

Are the Chemicals Released from Mattresses Harmful?

For most healthy adults, the low levels of chemicals from mattress off-gassing are not considered harmful and typically only cause temporary, mild irritation like headaches. However, for people with chemical sensitivities, asthma, or for young children, these VOCs can trigger more noticeable short-term effects like nausea, dizziness, or respiratory irritation.

This is easily the most important question we hear from families across Morris County and Northern New Jersey. As your local furniture experts for over 70 years, we believe you should know exactly what you’re bringing into your home.

The real issue boils down to the specific chemicals used. While most are regulated in the US, some unregulated, cheaper imports you might find online can release more problematic VOCs.

What are the specific chemicals of concern?

The primary health risks are linked to certain VOCs from petroleum-based foams and chemical flame retardants, such as benzene, formaldehyde, and naphthalene. Since we spend about a third of our lives sleeping, long-term exposure is something to consider, especially for sensitive individuals.

Some research has linked prolonged VOC exposure to serious health issues. A stark lab analysis, reported by industry expert Walter Bader, found that one memory foam mattress emitted 61 different VOCs, including known carcinogens like benzene and naphthalene.

This is exactly why, as part of our 5-Star Formula, we prioritize expert advice to ensure your family's safety. Some of the main VOCs identified in mattress studies include:

• Benzene: Often found in plastics and synthetic fibers, it's a known carcinogen.
• Formaldehyde: A common adhesive ingredient, it can cause respiratory and skin irritation.
• Naphthalene: Used in manufacturing, it can lead to neurological issues in high concentrations.

As a family business deeply rooted in the Roxbury Township community, your health is our priority. This isn't just a transaction for us; it's about making sure our neighbors are sleeping soundly and safely. That level of personal care is something you simply won't get from the big-box stores.

It really comes down to making smarter choices from the start. We work with trusted brands that are transparent about their materials and put safety first. Many of our vendors are committed to responsible manufacturing, and you can explore some of their sustainability measures to see how they reduce their environmental impact.

How Do I Reduce Off-Gassing Odors in My Home?

The best way to reduce off-gassing odors is to increase ventilation by unboxing the mattress in a separate, well-aired space and using fans and open windows to circulate fresh air. A little bit of airflow and patience go a surprisingly long way. You want to give those VOCs a quick and easy exit route so they can dissipate.

It's a question we get all the time from our neighbors across Morris County: "So, how do I get rid of this smell?" Think of it like airing out a room after you've painted—you just need to get the air moving.

This is actually one of the small perks our local customers in Succasunna and Roxbury Township appreciate. Unlike online companies that just drop a box on your doorstep, our White Glove Delivery team handles the entire setup. We can even unbox your new mattress in a well-ventilated garage or spare room if you ask, giving it a head start on airing out.

Your 4-Step Checklist for Minimizing Off-Gassing Odors

We've been sharing this simple, four-step checklist with families in Northern New Jersey for years. Follow these steps, and you’ll clear the air and enjoy your new mattress much sooner.

By following this game plan, you're not just masking the odor; you're actively helping it disappear for good.

How can I get rid of the smell faster?

To speed things up, use an air purifier with an activated carbon filter, which is specifically designed to trap and neutralize the VOCs that cause that "new mattress" smell. If you're particularly sensitive to smells or just want to go the extra mile, an air purifier can be a great ally.

To really tackle indoor air pollutants like VOCs, consider one of the best air purifiers for allergies. They provide an extra layer of freshness for your entire home.

How Can I Shop for a Safe and Low-VOC Mattress?

The most reliable way to find a safe, low-VOC mattress is to look for third-party certifications like CertiPUR-US®, GREENGUARD Gold, and OEKO-TEX®. These independent seals of approval are your best guarantee that a mattress has been rigorously tested for harmful chemicals and meets strict health and safety standards.

As your local furniture experts here in Succasunna for over 70 years, we’re here to cut through the noise. For our neighbors in Roxbury Township and across Morris County, learning to read these labels means you can shop with total confidence.

Decoding the Top Mattress Certifications

When you see a certification on a mattress tag, it’s not just marketing fluff—it’s a promise of safety. Think of it as a report card for your mattress. Here are the most important ones to know:

• CertiPUR-US®: This is the gold standard for polyurethane foams. A CertiPUR-US® seal guarantees the foam is made without ozone depleters, heavy metals like lead and mercury, formaldehyde, and specific phthalates. It also ensures low VOC emissions.

• GREENGUARD Gold: This certification tests the entire mattress—not just the foam—for over 360 different VOCs and sets an incredibly low limit for total chemical emissions. A GREENGUARD Gold certified mattress is an excellent choice for children, the elderly, and anyone in your Northern New Jersey home with respiratory sensitivities.

• OEKO-TEX® Standard 100: This label certifies that every single component, from the fabric cover to the thread and zippers, has been tested for harmful substances and is safe for human health.

The rise of these standards has been a total game-changer for the industry. Key milestones, like the launch of CertiPUR-US in 2008, have dramatically cut down on toxic emissions, with certified foams now showing an 80% reduction compared to their non-certified counterparts.

As a family business, we believe knowledge is power. Unlike an online-only retailer that can’t show you the difference, our expert team can walk you through these certifications right here in our showroom. We can show you exactly what makes one mattress a healthier choice than another.

Because so many of our mattresses are in-stock and displayed on our floor, they’ve already had significant time to air out. This naturally reduces your family’s exposure from day one.

Common Questions About Mattress Off Gassing

We get it—bringing a new mattress home is exciting, but a weird smell can be a real buzzkill. We hear these questions all the time from our neighbors in Morris and Sussex County. After more than 70 years in the community, you could say we’ve heard it all, so let’s clear the air.

Does mattress off-gassing last forever?

No, mattress off-gassing is a temporary issue that should fade completely within one to four weeks. That chemical odor is always at its worst in the first few days after you unbox a mattress, especially one that’s been sealed in plastic.

This is where shopping with us makes a huge difference compared to an online-only store. Our mattresses often get to air out in our spacious Succasunna showroom, which means much of that initial off-gassing is already done by the time your new bed arrives at your home.

Are organic or natural latex mattresses a better choice?

Absolutely. Mattresses made from 100% natural materials like organic latex, cotton, and wool are fantastic low-VOC alternatives. These materials aren’t made with the petroleum-based polyurethane foams that are the main source of significant off-gassing. They might have a faint, earthy scent, but that’s the natural aroma of the materials, not harsh chemicals.

Can I return a mattress because of the smell?

Return policies vary wildly, and many online brands will not accept a return for an off-gassing odor, writing it off as a normal part of the setup. This can leave you stuck with a mattress you don’t feel comfortable sleeping on.

This is a perfect example of where our 5-Star Formula at Suburban Furniture comes in. We talk with you about material sensitivities before you choose, so we can find a mattress you’ll love from day one. You just don't get that "Real Person Support" from a big-box store or a website.

Ready to find a mattress you can feel truly good about? The best way to make a confident choice is to "test drive" the options for yourself. We invite you to visit our Suburban Furniture showroom on Route 10 in Succasunna to speak with our friendly team of complimentary Design Consultants.
