The right car seat accessories make every ride safer, more convenient, and better suited to the way your family actually lives. At Posh Baby, we carry a carefully selected range of accessories for the car seats we sell — extra bases, travel bags, rain covers, stroller adapters, and more — all chosen for compatibility, quality, and genuine usefulness.

Extra Bases for Multi-Vehicle Families

An extra base is one of the most practical investments you can make after purchasing an infant car seat. Rather than reinstalling your seat every time you switch vehicles, a second base stays permanently installed — so every transfer is a simple click. We carry extra bases for the Nuna PIPA series, UPPAbaby MESA & Aria, and Clek Liing, each with the same installation confidence as the original.

Travel Bags & Car Seat Protection

Flying with a car seat without a proper travel bag is a risk not worth taking. Our travel bags are designed specifically for the seats we carry — protecting against gate-check damage, airline handling, and the inevitable bumps of travel. Many are registered with their manufacturer’s TravelSafe programs for added peace of mind.

Stroller Adapters & Travel System Compatibility

Pairing your infant car seat with a compatible stroller adapter creates a seamless travel system — no waking a sleeping baby, no extra gear. We carry adapters for Nuna, UPPAbaby, Clek, Cybex, and Maxi-Cosi seats across a wide range of stroller frames. Our team can confirm compatibility with your specific seat and stroller before you purchase.

Rain Covers, Inserts & More

From infant head inserts that provide extra support for newborns to rain covers that keep your little one dry during Pacific Northwest winters, our accessories collection covers the details that make daily life with a car seat easier. Every item we carry is vetted for safety and compatibility with the seats in our showroom.
