Travel System 2 in 1 Pram 3 in 1 iSOFIX Base - Black (iSafe iSOFIX Carseat Base) is available in Car Seats, Travel Systems

The isofix base itself is great however my 8 week old son has went from looking secure in car seat via seat belt to using the isofix and his head being tilted forward via isofix. I wasn't comfortable with his position and have therefore went back to using car seat via seat belt until he is strong enough to support his own head.
