Is there a smell? Analysis of the relationship between the smell and material of the inflatable mattress

Picture this: It's a Friday evening, and you've just unboxed that brand-new inflatable air mattress you ordered for your weekend guests. You're excited to set it up, but as soon as you pull it out of the packaging, a strong, somewhat chemical-like smell hits your nose. Suddenly, you're hit with a wave of questions: Is this normal? Will it go away? Is it safe to sleep on? If you've ever owned an inflatable product—whether it's an air mattress, a swimming pool, or even a bubble tent—you've probably encountered this scenario. The "new inflatable smell" is a common concern, but what causes it, and does it have anything to do with the materials used? Let's dive in and unpack the relationship between smell and material in inflatable mattresses, and why it matters for your comfort and peace of mind.

Why Do Inflatables Smell, Anyway? The Science of "New Plastic" Odor

First things first: that distinct smell isn't just your imagination. It's a real phenomenon, and it all comes down to something called off-gassing . When inflatable products are manufactured, they're made from synthetic materials—think plastics, rubbers, and fabrics—that are treated with various chemicals to enhance their flexibility, durability, and water resistance. During production, these materials can trap volatile organic compounds (VOCs), solvents, and residual chemicals from the manufacturing process. When you first open the box, these compounds start to evaporate into the air, creating that familiar "new plastic" scent.

VOCs are carbon-based chemicals that easily turn into gas at room temperature. Common ones in inflatables include plasticizers (used to make materials soft and bendable), adhesives, and even trace amounts of solvents used to clean molds during production. While the smell can be strong initially, the good news is that for most inflatable products—including your inflatable air mattress—off-gassing is temporary. As the materials "breathe" and release these trapped compounds, the odor fades over time. But here's the key: how quickly it fades, and how intense it is in the first place, depends almost entirely on the material.

The Materials Behind Your Inflatable Mattress: What's It Made Of?

Not all inflatable air mattresses are created equal, and neither are their materials. Manufacturers choose materials based on cost, durability, weight, and intended use—and each material has its own off-gassing profile. Let's break down the most common materials you'll find in inflatable mattresses and how they contribute to that initial smell.

1. Polyvinyl Chloride (PVC): The Budget-Friendly Workhorse

PVC is the most widely used material in inflatable products, from budget inflatable air mattresses to giant inflatable swimming pools. It's cheap, highly durable, and excellent at holding air and water—qualities that make it a favorite for manufacturers. But there's a catch: standard PVC is often mixed with phthalates , a type of plasticizer that keeps the material from being stiff and brittle. Phthalates are the primary culprits behind that strong, chemical-like smell in many new inflatables.

During production, PVC sheets are heated, molded, and sealed, and residual phthalates and solvents can get trapped in the material. When you inflate the mattress for the first time, these chemicals start to evaporate, leading to that intense "new plastic" odor. I've tested dozens of PVC inflatable air mattresses over the years, and the smell can range from mild to eye-watering—depending on the quality of the PVC and the amount of plasticizer used. Cheaper models tend to have stronger smells because they often use lower-grade PVC with more phthalates to cut costs.

2. Thermoplastic Polyurethane (TPU): The Eco-Friendly Alternative

In recent years, TPU has emerged as a more eco-friendly and low-odor alternative to PVC. TPU is a flexible plastic that's free of phthalates and other harmful chemicals, making it a popular choice for higher-end inflatable air mattresses and specialty products like inflatable bubble tents. Unlike PVC, TPU doesn't require plasticizers to stay flexible, which means fewer VOCs to off-gas. As a result, TPU inflatables typically have a much milder initial smell—often described as "rubbery" or "fresh" rather than chemical.

I recently tested a TPU inflatable bubble tent (yes, the kind you see all over Instagram for glamping!) and was struck by how little it smelled compared to my old PVC air mattress. When I unboxed it, there was a faint, almost sweet scent, but it was gone within 24 hours of airing it out. TPU's downside? It's more expensive than PVC, so you'll pay a premium for that low-odor experience. But if smell sensitivity is a priority for you, it might be worth the investment.

3. Nylon and Polyester Blends: Lightweight and Low-Odor

Some inflatable air mattresses—especially lightweight, backpacking models—use nylon or polyester fabrics coated with a thin layer of TPU or PVC. These blends combine the best of both worlds: the durability of synthetic fabric and the airtight seal of plastic coatings. Because the plastic layer is thinner, there are fewer chemicals to off-gas, resulting in a milder smell. I own a nylon-polyester inflatable air mattress for camping, and when I first opened it, I could barely smell anything—just a faint "new fabric" scent, similar to unboxing a new t-shirt. After 12 hours of airing, even that was gone.

These blends are also popular in products like inflatable water mattress sun decks, which need to be lightweight enough to float but durable enough to support weight. A friend of mine has one on her pool, and she jokes that it smelled "like a new beach towel" when she first inflated it—hardly noticeable, and gone by the end of the day.

Beyond Material: What Else Affects Smell Intensity?

While material is the biggest player in determining smell, other factors can amplify or reduce that initial odor. Let's break down a few variables that might affect how your inflatable air mattress smells when you first use it.

Age of the Product

Believe it or not, the age of the inflatable matters. If your air mattress sat in a warehouse for months after production, it might have already off-gassed most of its VOCs, resulting in a weaker smell when you unbox it. On the flip side, a product that's fresh off the assembly line will have more trapped chemicals, leading to a stronger initial odor. I once bought a "display model" inflatable swimming pool from a store, and it smelled almost nothing—turns out, it had been inflated in the store for weeks, so the off-gassing was already done!

Storage Conditions

How the product is stored before purchase can also impact smell. If an inflatable air mattress is stored in a hot, sealed container (like a cardboard box in a warehouse during summer), the heat can accelerate off-gassing, but the trapped fumes will make the smell more intense when you open it. Conversely, products stored in cool, well-ventilated spaces might have a milder odor because some VOCs have already escaped during storage.

Inflation and Usage Environment

Once you take your inflatable air mattress home, how you use and care for it can speed up or slow down smell removal. Inflating it in a small, stuffy room (like a closet or bathroom) will trap the off-gassed VOCs, making the smell seem stronger and linger longer. On the other hand, inflating it in a well-ventilated area—like a garage with the door open or a backyard—will let those fumes escape, reducing the smell faster. Temperature also plays a role: warm air speeds up off-gassing, so inflating your mattress in direct sunlight (if the material allows) can help release trapped chemicals more quickly (just be careful not to overheat TPU or fabric blends, as they can degrade in extreme heat).

Practical Tips: How to Get Rid of That Inflatable Smell

Okay, so you've unboxed your inflatable air mattress, and it smells stronger than you expected. Don't panic—there are simple steps you can take to reduce or eliminate the odor. Here's what I've learned from years of testing inflatables:

1. Air It Out—The Most Effective Method

This is the golden rule. As soon as you unbox your inflatable air mattress, inflate it fully and place it in a well-ventilated area. If the weather is nice, set it outside in a shaded spot (direct sunlight can damage some materials, especially PVC). If you're indoors, open windows and use a fan to circulate air. For extra credit, flip the mattress halfway through to ensure both sides get aired out. I did this with a PVC inflatable swimming pool last summer: I left it inflated in my backyard for 3 days, and by the time my kids wanted to use it, the smell was completely gone.

2. Clean It Gently (If Needed)

If airing out alone isn't enough, a mild cleaning can help remove surface residues that contribute to smell. Mix warm water with a few drops of mild dish soap (avoid harsh detergents or bleach, which can damage the material) and wipe down the mattress with a soft cloth. Rinse with clean water and let it dry completely. I tried this on an old PVC air mattress that had been stored in a damp basement and developed a musty smell—it worked like a charm. Just make sure to dry it thoroughly to prevent mold, which can cause its own odors.

3. Use Baking Soda for Stubborn Odors

Baking soda is a natural deodorizer that can absorb lingering smells. Sprinkle a thin layer over the inflated mattress, let it sit for 4–6 hours, then vacuum it off with a soft brush attachment. I've used this trick on everything from inflatable air mattresses to inflatable bubble tents, and it's especially helpful for musty or mildew smells. Just avoid using too much baking soda, as it can get stuck in crevices around the valves.

4. Store It Properly to Prevent Future Smells

Once the smell is gone, proper storage will keep it that way. Always clean and dry your inflatable air mattress thoroughly before deflating it. Store it in a cool, dry place (avoid basements or attics with high humidity) and keep it in a breathable storage bag (not the original plastic packaging, which traps moisture). I store my TPU air mattress in a cotton duffle bag, and it's never developed a smell between uses.

How Does an Inflatable Mattress Compare to Other Inflatables?

You might be wondering: If inflatable air mattresses can smell, what about other inflatables I own, like my inflatable swimming pool or inflatable water mattress sun deck? The short answer: It depends on the material, but the same principles apply. Let's compare a few common inflatables to see how their smells stack up.

Inflatable Swimming Pools vs. Air Mattresses

Most inflatable swimming pools are made from standard PVC, which means they often have a strong initial smell—sometimes even stronger than air mattresses. Why? Because pools are thicker and have more material, which means more surface area for off-gassing. My neighbor once told me she was so put off by the smell of her new pool that she almost returned it. After leaving it inflated in her backyard for a week (and hosing it down daily), the smell faded, and now her kids use it every summer. The takeaway: pools need extra airing time, but the smell is temporary.

Inflatable Bubble Tents vs. Air Mattresses

Inflatable bubble tents are often made from TPU or high-grade PVC (for clarity and durability). As we discussed earlier, TPU bubble tents have a mild, short-lived smell, while PVC ones can be stronger. A friend of mine runs a glamping business and swears by TPU bubble tents for this reason: "Guests hate that 'new plastic' smell when they're trying to relax," she told me. "TPU tents air out in a day, and no one complains." If you're considering a bubble tent for camping or events, opt for TPU if smell is a concern.

Inflatable Water Mattress Sun Decks vs. Air Mattresses

Inflatable water mattress sun decks are designed for lounging on water, so they're often made from lightweight, quick-drying materials like nylon-PVC blends. These blends have thin plastic coatings, which means less off-gassing and a milder smell. I tested one last summer, and it smelled like a new beach towel—faint and gone within hours. Because they're used outdoors, they also get plenty of natural airing, which helps keep odors at bay.

The Bottom Line: Smell Is Normal, but Material Matters

At the end of the day, that "new inflatable smell" is a normal part of owning products like inflatable air mattresses, pools, or bubble tents. It's caused by off-gassing of chemicals trapped in the materials during manufacturing, and for most people, it's nothing to worry about. The intensity and duration of the smell depend almost entirely on the material: PVC is strong-smelling and slow to off-gas, TPU is mild and fast, and fabric blends are barely noticeable.

If you're sensitive to smells, invest in a TPU or nylon-polyester blend inflatable air mattress—you'll pay more, but you'll avoid the hassle of strong odors. And no matter what material you choose, remember: airing out is your best friend. A little patience (and maybe some baking soda) will have your inflatable smelling fresh and ready for use in no time.

So the next time you unbox an inflatable and catch a whiff of that "new plastic" scent, take a deep breath (literally!). It's just your mattress (or pool, or bubble tent) getting ready to become your new favorite outdoor companion—odor-free.
