Choosing between two premium stroller brands can feel like choosing between two chemistry textbooks. The reassuring news is that both UPPAbaby and Nuna make strollers designed to meet required safety standards; the more useful question is how their fabrics, coatings, foams, and plastic parts fit your family’s priorities.
Uppababy vs. Nuna: Material Safety in Strollers is not a simple “safe versus unsafe” decision. Both brands’ strollers must meet applicable U.S. requirements for structural safety and restricted substances, including limits on lead and certain phthalates. Look for model-specific disclosures, avoid unnecessary stain-resistant treatments, and focus on ventilation, cleanability, and regular inspection.
Understanding the Science
A stroller contains several material categories, and each deserves a slightly different lens:
| Stroller component | What it may include | What parents should consider |
|---|---|---|
| Frame | Aluminum or steel, paint, coatings | Check for damage, peeling, or corrosion |
| Seat fabric | Polyester, nylon, cotton blends, dyes, finishes | Skin contact, breathability, cleaning instructions |
| Padding and foam | Polyurethane or other cushioning materials | Odor, ventilation, and flame-retardant disclosures |
| Harness and buckles | Webbing, plastic, metal hardware | Secure fit and intact parts matter most |
| Handlebar and tray | Foam, rubber-like materials, plastics | Avoid chewing or prolonged mouthing when possible |
| Canopy and basket | Woven textiles and coatings | Ask whether water- or stain-resistant finishes are used |
In the United States, strollers are covered by a mandatory safety rule incorporating ASTM F833. The requirements address hazards such as entrapment, stability, restraint performance, braking, and labeling.1 Children’s products must also meet limits for lead in paint and accessible components, while regulated phthalates are restricted in certain accessible plasticized parts.1
These rules provide an important baseline, but compliance does not mean every stroller has identical materials. Brands may use different textiles, foams, dyes, waterproofing treatments, or supplier specifications. A “non-toxic” label can also be vague unless the company explains what it excludes, which models are covered, and whether claims apply to the finished product or only selected components.
UPPAbaby materials
UPPAbaby states that its car seats contain no added flame-retardant chemicals applied to materials in direct contact with a child.2 That statement is useful, but it applies specifically to car seats—not automatically to every stroller model or every stroller component.
Independent reporting has also described UPPAbaby’s broader materials direction, including claims involving PFAS elimination and the absence of certain chemicals. However, parents should verify the exact model and production date rather than assuming that a brand-level statement covers every product.
Nuna materials
Nuna markets several products with material-conscious features, including fabrics and foam described as free from added fire-retardant chemicals in some product categories. Independent testing reported no detectable PFAS in tested Nuna PIPA car-seat fabric samples, but car-seat results should not be treated as proof that every Nuna stroller fabric is PFAS-free.3
This distinction matters: testing one model is not the same as testing an entire product line. If a stroller’s water resistance, stain resistance, or performance claims are important to you, ask the manufacturer which finish is used and whether the finished fabric has been tested.
Uppababy vs. Nuna: Material Safety in Strollers
There is no reliable universal winner because materials can change by model, colorway, market, and manufacturing year. A practical comparison looks like this:
| Question | UPPAbaby | Nuna |
|---|---|---|
| Meets U.S. stroller safety requirements? | Products sold in the U.S. must comply with applicable requirements | Products sold in the U.S. must comply with applicable requirements |
| Added flame-retardant information | Public claims exist for certain UPPAbaby car-seat materials | Public claims exist for some Nuna product categories |
| PFAS information | Brand and third-party reporting indicate progress, but verify the stroller model | Some independent testing exists for Nuna car-seat fabric, not every stroller |
| Best verification step | Request the model-specific chemical or materials statement | Request the model-specific chemical or materials statement |
| Everyday priority | Fit, ventilation, cleaning, and condition | Fit, ventilation, cleaning, and condition |
Neither a higher price nor a “premium” label guarantees a meaningful difference in chemical exposure. For most families, the baby’s actual exposure is more affected by direct skin contact, mouthing, heat, sweat, dust, and how the stroller is cleaned than by tiny differences in marketing language.
If your baby has eczema or very reactive skin, fabric contact deserves extra attention. Fragrance-free cleaning, breathable clothing, and washing removable textiles according to the manufacturer’s instructions may help. Stroller materials can contribute to irritation, but contact dermatitis has many possible triggers, including detergents and personal-care products. See Contact Dermatitis In Babies Common Triggers At Home for a broader troubleshooting guide.
Tips for Parents
-
Check the exact model. Material claims may differ between a full-size stroller, travel stroller, bassinet, and car seat.
-
Ask precise questions. Request information about PFAS, added flame retardants, phthalates, BPA, lead, PVC, and stain-resistant finishes in the finished product.
-
Do not confuse odor with toxicity. A new-product smell can come from volatile compounds, packaging, or adhesives. Airing out the stroller in a well-ventilated area is reasonable; persistent strong odor warrants contacting the manufacturer.
-
Wash removable fabric before first use. Use the care label, a fragrance-free detergent, and thorough drying. Do not use bleach or unapproved treatments that could damage fire, water, or structural properties.
-
Avoid aftermarket sprays. Waterproofing, disinfecting, fragrance, and stain-resistant sprays can introduce chemicals the original manufacturer did not evaluate.
-
Inspect high-contact areas. Replace damaged harness webbing, cracked buckles, peeling coatings, or deteriorating foam.
-
Prioritize correct use. A properly fitted harness, locked frame, working brake, and weight-appropriate seat are immediate safety priorities under stroller safety guidance.1

Duckie’s Verdict: Is it safe?
Yes—with model-specific caution. UPPAbaby and Nuna strollers are subject to mandatory safety requirements, and available brand information does not support treating either entire brand as inherently unsafe. The strongest choice is the specific model with clear materials information, no unnecessary aftermarket coatings, good ventilation, and a design you can use correctly every day.
For Uppababy vs. Nuna: Material Safety in Strollers, choose based on the exact fabric and finish disclosures—not vague “non-toxic” promises. If your baby has eczema, allergies, or unusual symptoms after contact, stop using the suspected item and discuss persistent symptoms with your pediatrician.

FAQ
Is Nuna safer than UPPAbaby?
No clear evidence shows that one brand is universally safer. Both must meet applicable stroller safety requirements. Compare the exact model’s materials, disclosures, fit, ventilation, and condition rather than relying on brand reputation alone.
Are UPPAbaby and Nuna strollers PFAS-free?
Do not assume every model is PFAS-free. Testing and company statements may apply only to specific products or materials. Ask for a current, model-specific statement covering the finished stroller.
Do strollers contain flame retardants?
Some stroller materials may be designed without added flame-retardant chemicals, but claims vary by product category and model. Verify whether the statement covers the stroller fabric, foam, and other components—not only a related car seat.
What is the safest way to clean a stroller?
Follow the manufacturer’s care instructions, use mild fragrance-free detergent on removable fabrics, and air-dry thoroughly. Avoid unapproved disinfectants, fragrance sprays, waterproofing products, and stain-resistant treatments.
