The Kompressor 4 Astra is an upgraded and updated version of our popular Kompressor Series 0 4 convertible car seat. The Kompressor 4 is an A4 Rearward Facing seat, allowing extended rearward facing to a large 30 month old, and then forward facing to a large 4 year old. Despite the upgrade, its still nice and compact at 44cm across the widest point. Thanks to a new, ultra-low-profile base, its also 3.5cm shorter than the Kompressor II.
