Clek Fllo fit guide
A premium 17-inch convertible engineered specifically for three-across installs and extended rear-facing. Here's exactly which children it fits, how NHTSA rated it, and which cars it fits — including three-across.
Which children it fits
| Mode | Weight | Height | LATCH limit |
|---|---|---|---|
| Rear-facing | 14 lb – 50 lb | up to 43" | up to 40 lb on lower anchors |
| Forward-facing harness | 22 lb – 65 lb | up to 49" | up to 40 lb on lower anchors |
Weight/height limits are the seat's NHTSA-published values. Beyond the LATCH limit, install with the vehicle seat belt instead of the lower anchors. Always follow the labels on your seat and the vehicle manual.
NHTSA Ease-of-Use detail
NHTSA's Ease-of-Use rating measures how easy a seat is to install and use correctly — the single biggest factor in real-world safety, since most seats are installed wrong. It is not a crash-test score; NHTSA does not crash-rate individual car seats.
Which cars the Fllo fits three across
At 17" wide, three Fllos should fit across the back of these vehicles we track (test-fit to confirm):

How is the Clek Fllo rated by NHTSA?
NHTSA gave the Clek Fllo an Ease-of-Use rating of 3/5 stars, including 3/5 for vehicle-installation features. Ease-of-Use measures how easy the seat is to install and use correctly — not crash performance, which NHTSA does not rate for individual seats.
