## What reviewers say

**Nuna PIPA rx Infant Car Seat** — Only one whitelisted tester (Wirecutter/NYT) covers the exact Pipa rx, and only within its competition roundup rather than as a standalone hands-on pick. It praises the well-designed Relx base that ships with the rx and calls the Nuna line lightweight, stylish, and easy to use, but concludes that at close to $400 the Uppababy Aria (its upgrade pick) is a far better choice. No crash-test or other measurements are reported for the rx. (1 sourced review.)
