The Evolva 123 Plus car seat from Britax grows with your child from 9 to 36kg which is approximately 9 months to 12 years. It's designed with a 5 point harness which has a simple one pull adjustment for children from 9 18kg. The harness is height adjustable and so is the head rest, providing ultimate protection and comfort. It has side impact protection with deep, softly padded side wings. The seat shape has been carefully made to ensure that the lap belt sits in the correct position when the chair is used as a highback booster seat, while the seat belt guide correctly positions the diagonal belt when in booster seat mode. The Britax Evolva 123 Plus also features harness retainers which keep the harness out of the way when your child is getting in or out of the seat. It has an upright and recline position, pull out drink holder, and a snack tray. All our car seats and infant carriers comply with current European regulations ECE R44 03 or ECE R44.04.
