The Safety 1st TriMate All-in-One Convertible Car Seat and Safety 1st Grand 2-in-1 Booster Car Seat bundle keeps children safe and comfortable in the car from birth through the pre-teen years. The TriMate transitions through three modes - rear-facing, forward-facing with a harness, and belt-positioning booster - supporting babies from 5-40 lbs and up to big kids 100 lbs. Its slim 17” width allows three seats across the backseat. The Grand covers forward-facing and booster modes from 30-100 lbs. Both seats feature headrests and harness systems that adjust easily as children grow. With deluxe fabric and memory foam inserts, these seats prioritize comfort. Their lightweight builds and dishwasher-safe cupholders add convenience for busy parents. As an added perk, the TriMate's machine-washable pads simplify cleanup of messes. Together these versatile seats accommodate growing kids in one seamless transition. The TriMate handles the early years in rear and forward-facing modes. Then the Grand takes over in booster mode through the grade school years. This bundle eliminates the need for multiple seat upgrades, providing safety, comfort and value for families with children close in age.
