This review represents the installation with seat belt but it can also be installed with the Joie i-Base Isofix.

Joie i-Gemm is a very safe and lightweight seat with its 4.6 kg. Joie recommends to use i-Gemm for a maximum of 5 year period.

It can also be used as a carrier and a travel system on several buggies and strollers with a Maxi-Cosi adapter, and also without an adapter on its perfect match, the Joie Chrome 3in1, as well as on most Joie strollers.

Lie-flat or close to lie-flat position is not possible.

The seat can be used both with seat belt and isofix – a very good option if you want to have an isofix seat but need the flexibility and possibility to use it with a seat belt once in a while.


  • The head is protected by 3 layers, including a memory foam called Intelli-Fit™.
  • Side impact protection is provided by the patented Intelli-Fit™ foam.
  • You can adjust the headrest and the padded harness with a central adjuster easily with one hand into 7 different positions.
  • A full body and head insert comes with the seat to support newborn babies.
  • The base is curved so that you can also rock and relax your baby in the seat.
  • A full coverage sun canopy with UPF 50+ is also part of the seat, that also has a zip-open mesh panel and it is also fully removable.
  • You can also choose to have the seat together with its base to make it safer for your baby and easier for you.
  • The carry handle is ergonomic.

There are two colors you can choose from, both of them are very elegant: pavement gray or black with white dots.

When the car seat is installed on the front passenger seat, you must switch off the front passenger airbag.
