Description

Compatible with Cloud G3, Sirona G3, Cloud G i-Size, and Sirona G i-Size, it offers the flexibility you need with a growing child. A safety-conscious Driving Direction Control (D.D.C.) button setting ensures the Cloud G3 can only be attached and used in a rear-facing position. Two further settings let you decide if the Sirona G3 is used forward or rear-facing. User-friendly ISOFIX-Release buttons keep installation simple, and extra stability comes from a cleverly-designed load leg.
