The Nuna BASE curv in Black is the newest addition to the NEXT system. The base rotates 360 and features ProxiPivot, a unique arch design bringing baby closer, making installs and harnessing that little bit easier. The BASE curv comes with colour indicators to assure you the base is fitted correctly in the car, and that the car seat is securely fitted to the base, and a Slide Smart swivel lock which ensures the car seat is kept rear-facing until little one is atleast 15m and 76cm.
