I'm looking for a new car seat for my recently turned 3yo as she's fairly tall for her age and about to outgrow her baby seat.

I saw the Infa Secure Rovette convertible booster seat for sale in the latest Kmart catalogue and am wondering if it's any good? I want something this will last her through until she no longer needs a car seat.

It won't be her main car seat as I already have a MaxiRider that I'm about to switch her over to in my car for her - the seats will be used in my DH's car and another needed for my mum's car as she also helps with picking up my DD from child care, etc.

Any advice on whether this car seat is any good would be much appreciated.
