So on this seat there are hardly anything to say. Stiftung Warentest and ADAC have (without Isofix attachment) gekührt the Maxi-Cosi Citi SPS (Side Protection System) in 2007 as winner of the universal seats. The handling is very simple. The Citi SPS is in contrast to the CabrioFix also approved for the aircraft, slightly lighter, has a side-impact protection system and is cheaper. Why this model is cheaper than the CabrioFix, probably understands only the company itself. Due to the short life I would always prefer this model. The actual practice test I would, however, never have to make.
