The Parkway SGL Belt-Positioning Booster Seat with ISOFLEX flexible Lower latch Connection System secures the booster seat to the vehicle, stabilizes it during a crash, and prevents it from becoming a projectile when not in use. The Parkway SGL also features SecureGuard anti-submarining technology and industry leading True Side Impact Protection to manage crash forces and minimize injury to your child during a crash. Designed to be easily installed in seconds with only two clicks and a pull, the Parkway SGL booster seat is appropriate for children 40 pounds and up.  A removable backrest, dual retractable cup holders, color-coded vehicle belt guides, and a one-hand quick-adjust head restraint make the seat convenient and easy to use each and every time.
