The Diono SeatGuard Complete's molded high density foam provides a solid and stable surface which is ideal to prevent damage from heavy car seats. The full back panel keeps dirty feet off the back of the vehicle seat when your child is rear-facing, and the lower panel protects the edge of the seat when forward-facing. The hard-wearing shell ensures longevity while the raised edge contains, dirt, crumbs and spills. Compatible with all infant carriers, car seats and booster seats. LATCH compatible.
