The UPPAbaby Mesa Extra Base gives your family the freedom to keep a dedicated base in every vehicle — no more swapping between cars, coordinating with babysitters, or rushing through reinstallation. With the SmartSecure System on board, correct installation is fast, intuitive, and verifiable every time.

SmartSecure Installation You Can Trust

Self-retracting mini LATCH connectors make attachment straightforward, while the red-to-green tightness indicator gives you a clear visual confirmation that the base is properly secured before you drive. The streamlined, low-profile design keeps the base sitting flush in your vehicle, and the smooth finished base bottom protects your car’s upholstery. Our CPST-certified staff installs and checks car seat bases daily in our Portland showroom — and every Mesa purchase at Posh Baby includes a complimentary car seat safety installation and safety check by our trained staff.
