The harness adjustment is genuinely tool-free, which made switching it between our two cars a five-minute job. It fits rear-facing in our sedan without the front passenger giving up all their legroom, and the slim profile leaves room for a third passenger. Four modes means we're done shopping for se

Our narrow SUV can barely fit two seats across, yet this one slides in without touching the doors—the slim profile is exactly what we needed. The canopy is a nice bonus for shielding him from the sun on long drives, and switching from rear-facing to forward-facing took me under ten minutes.

The 4-in-1 design is a lifesaver for our small sedan, the Slim Plus profile leaves room for the front passenger without cramping our legs. The harness adjusts smoothly to each growing stage, and the seat itself is padded enough that my toddler actually enjoys the ride.
