## What reviewers say

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. (Based on 1 review, 2026-02-04.)

Praised: The Relx base that ships with the rx is better designed and holds the seat securely in place; Lightweight, stylish, and easy to use.
Flagged: Expensive (near $400); Wirecutter says the Uppababy Aria is a far better choice at that price; Only the Relx-base rx models are worth considering; the cheaper Pipa-series base has a design flaw.
Disagreement: Only one whitelisted source covers the exact rx, so no cross-source comparison is possible. Wirecutter is lukewarm on the rx and steers buyers toward the Uppababy Aria at the same price point.
