Eli C. ★★★★★

The belt guides click into place so easily that my five-year-old can do it himself, and the raised sides give him just enough height to stop slouching under the shoulder strap. We’ve taken it on three road trips already and it’s held up great in the back seat.

Abigail ★★★★★

The seatbelt fits across my son's chest perfectly now, no more riding up on his neck. It's so light I can move it between our two cars without a struggle, which makes school runs a lot easier.

Alexander M. ★★★★★

My daughter finally sits tall enough that the shoulder belt crosses her chest instead of her neck, and the lightweight frame makes it easy to move between our two cars. It's been a solid few weeks of daily rides and the seat shows no signs of wear, which is exactly what I was hoping for.
