From the Same Collection

Wheeled Car Seat Travel Pack

$119.99

No Added Formaldehyde

Formaldehyde is something you want to stay away from because it is a cancerous, strong-smelling, colorless gas commonly found in pressed-wood products.

Phthalates Free

Phthalates disrupt the body's hormones and some are known carcinogens. The chemicals from baby gear and wallpaper can be ingested, inhaled or absorbed.

No PFAS

PFAS-free baby products do not contain poly-fluorinated alkyl substances which are a group of around 4,700 industrial chemicals that can be found everywhere around us.

No Added Fire Retardants | Potential Trace Carryover

While no products sold on Modern Nursery have any added chemical fire retardants, some may be manufactured in the same facilities as others that do and therefore may have potentially been exposed to FR chemicals. If you're looking for a product that is 100% FR-free, we have those too - just look for the Fire Retardant Free badge on the listing!

Recycled Materials

Recycling is a trend, and we love it! Consumerism is a huge problem today, and there are ways to combat the issue. Recycled materials help keep our landfills clean, and also saves energy, water and money.

The Maxi-Cosi Pria Max All-in-One Convertible Car Seat is a car seat that is ready to grow with your little one and is the only car seat you will ever need! Made with parents and babe in mind, this seat features a comfortable and secure design that makes going on family adventures a walk in the park.

Busy hands? No problem. ClipQuik™ features a magnetic chest clip that clicks open with one hand, and makes unbuckling struggle-free, and the Out-of-the-Way spring-assist harness holders keep straps from playing hide-and-seek, so getting in and out is quick and easy. Growth spurts happen overnight and the Maxi-Cosi Pria Max All-in-One Convertible Car Seat is ready by morning! Designed to grow with your little one from that first ride home to big kid days! QuikFit™ lets you raise the headrest and harness with just one hand, no rethreading required. 

Comfort is woven into every detail. EcoCare fabric - made from 100% recycled plastic bottles - creates a soft, breathable seat that’s gentle on your little passenger and kinder to the planet. Additionally, plush PureCosi™ fabric is made without added fire-retardant treatments for a cleaner, cozier ride.

Free of added fire retardants

Maxi-Cosi is fully transparent about their manufacturing process and guarantee that their car seats are completely free of any added fire retardants. However, their products are manufactured in the same facilities as other gear that does contain FRs so there is a chance of potential FR carryover. We believe in full disclosure and transparency and appreciate Maxi-Cosi's honesty and effort to produce fire resistant products without the addition of chemical fire retardants.

At Modern Nursery, we are committed to selling only car seats with no added fire retardants. Check out our blog post to read more about FRs, different levels of FR-free standards, as well as find out which brands are on our “clean list” and which ones we do not recommend.
