Mother's Choice Harmony 0-4yr Convertible Car Seat $179 (was $299) @ eBay AU

The Harmony convertible car seat is designed to take bub from birth to approximately 4 years of age. For newborns, the seat faces towards the back of your vehicle to protect your little one's delicate neck. After bub’s shoulder reaches the lower height marker or approximately 1 year of age, the car seat is to be used in the forward-facing position.

It is incredibly easy to install the base for this seat, and you can fit up to three of them in the back of your car. An in-built rebound bar minimises recoil after a crash, so you can have confidence that your baby is as safe as possible in rearward-facing mode. In forward-facing mode, you can adjust the seat to three distinct recline positions to enhance bub's comfort, especially on long drives.

An infant insert provides a snug, secure fit for small babies, and you can remove it as your child grows. Padded belt mates enhance comfort even further. Both the infant insert and seat cover are machine washable for convenient cleaning. There is a two-year warranty on the seat cover and a six-year warranty on all hardware
