Maxi-Cosi Pria Max 3-in-1 Convertible Car Seat, Pure Cosi


The Maxi-Cosi Pria Max 3-in-1, because they grow up so fast.  If you’re reading this, you know all too well that choosing the right car seat is a tedious, scary, and super important decision. Why go through it more than once? Seriously, what parent has time for that? Thankfully, the PRIA Max 3-in-1 may just be the only car seat you’ll ever need. (Unless, that is, yet another little one comes along – but we’ll cross that bridge when we get there.) See, the PRIA Max 3-in-1 is built to grow with your child. And, most importantly, you can convert to new seat stages in mere seconds –  because trust us, growth spurts really do happen overnight. Bottom line? The PRIA’s here for the long haul.

Now in the Pure Cosi fabric that meets flammability standards through fabric and design choices; not with added chemicals. In turn, protecting your baby from toxins while reducing the accumulation of PBDEs and PFAS in the environment.
