Excellent condition seat from clean, non-smoking home - we have had two sets (4) I two cars so minimal wear. Harness mode from 11kg and easily converts to booster for children up to 54kg

SUPERIOR PROTECTION 2 layers of side protection formed by a deep foam-lined shell and quick-adjust head protection. Impact-absorbing base compresses to reduce the rough force of a collision. Impact-stabilizing steel frame offers superior strength where you need it most: at the connection point to the vehicle. V-shaped tether minimizes seat rotation with a unique two-strap design. Britax-patented staged-release stitches slow the seat’s forward movement during a crash. Impact-absorbing harness pads slow your child’s forward movement during a crash. Compatible with SecureGuard Clip (sold separately) to keep proper seatbelt alignment over hips and prevent children from sliding under the seatbelt in booster mode. Aircraft travel-certified when in harness mode. Proudly engineered, tested and made in the USA with global components for top safety and quality. SAFEST AND SIMPLEST INSTALLATION ClickTight Installation System makes safe installation as simple as buckling a seat belt. Easy-on/off lower anchors for an alternative installation method. SMART DESIGN Hassle-free transition from harness to booster mode by tucking away straps in the seat. Easy-buckle system keeps buckles and straps out of your way when positioning your child. Easy-remove cover pulls free of the car seat for cleaning without having to remove the harness. Cup holders and storage for drinks, food and toys. MAXIMUM FIT AND COMFORT No-rethread 9-position harness quickly adjusts with the push of a button as your child grows. Quick-adjust 2-position buckle easily moves outward as your child gets bigger. Multiple-position recline allows your child to relax in comfort. Plush memory foam padding for premium comfort.
