The Joie i-Gemm (NOT the same seat as the Joie Gemm) is one of the top rated infant seats by independent crash testers, rating “very good” on multiple test categories. It also did not have a single “inadequate” rating, which is exceedingly rare #CarseatFullstop rating – 4.5/5 The i-Gemm is a rearward facing infant car seat. The seat should be used until your baby is either 13kg or 85cm and uses a 5-point harness. It can be very safely installed with the seatbelt alone, but you can buy the ISOfix base separately. The seat has good padding, including extra padding for use with newborns. It is well designed for a growing baby, spacious and the headrest and harness can be adjusted as baby grows, without rethreading. Crash testing explained by #CarseatFullstop here (link). Safety Ratings: Passed basic safety standard: i-Size (R129) External testing: ADAC +1.5 with seatbelt (Very Good); +1.7 with base (Good) Which? Best Buy 78% (with seatbelt); Best Buy 77% (with base) We do not recommend using any car seat other than an infant car seat for a baby under 13kgs or 75cm. An infant seat is specifically designed to protect your developing baby.
