Designed for kids weighing 4 – 120 lb, the top-selling premium car seat in America in 2022* – the Revolve360 – grows with your child, offering 10 years of use and 3 modes. Install it just once and you’re done, thanks to the Sure360™ Safety Installation System, featuring the LockStrong™ bar, which pulls down to lock the car seat base into place and Tether360™, which helps keep the seat positioned and secure in the car. *Source: The NPD Group / Retail Tracking Service / US / Car Seats / YTD June 2022, Seats priced $300 and above
