The Cybex Sirona Plus is both a rear and front-facing seat that has a linear side-impact protection (L.S.P. system) which absorbs the force of a side-impact collision at a very early stage. The built-in, seat-to-chassis technology also ensures the impact is directed straight to the chassis of the car seat, and distributed evenly to protect your child. The Sirona Plus is also incredibly easy to use – the 360° rotation and a one-pull harness system with magnetic points makes is easy to get your baby in and out. And so that your baby is as comfortable as possible, the Sirona Plus features seven recline positions (easily adjustable with just one hand), and a head rest with eleven height positions. The five-point harness can be adjusted in one fluid movement – this truly is a carseat that grows with your child, designed for comfort, style and above all, safety.
