Cybex isofix carseat (New Marston OX3)

Cybex isofix car seat with adjustable headrest, suitable from toddler through to about 8 years old. It is a bit stained with food from my children using it, but in full working condition and never in an accident. Can be clipped into the isofix system in the car, or just fixed in with a seatbelt. My child has grown out of this.
