Before J was born, I did a lot of research into which carseat was the best option for me.
I wanted an infant carrier with a carseat base, but I didn't have IsoFix in my car, which meant that I needed a base that could be secured using the 3 point seatbelt.
As there is no standard length for seatbelts or seatbelt webbing in vehicles, when fitting a carseat using the 3 point seatbelt it is always recommended that you have a physical fitting from trained staff prior to purchase to confirm suitability.
The Maxi Cosi EasyBase 2 was suitable for use in my car at the time (a 1999 VW Polo) In combination with this base, we used the Maxi Cosi CabrioFix carseat (though the Maxi Cosi Pebble is also compatible with the EasyBase 2.)
The advantage of having a carseat base meant we could leave the base secured in the car and just click the carseat on and off as necessary. It saved time when we were going out, rather than having to mess about fitting the carseat every time you just got baby into the carseat in the house, carried the carseat to the car and clicked it onto the base before setting off. I was confident every time that the seat was correctly fitted and it saved time when going out with baby - which any new mum will tell you is a bonus!
J was very tall even as a young baby, but the CabrioFix was long enough for him to last quite a white. We removed the lumbar support cushion at around five months old as he needed the additional space for his bottom - the headhugger remained in place til he was 9 months. When I adjusted the harness on the carseat to come through the top holes, I brought it through the bottom holes of the headhugger to hold it in a higher position in the seat to be able to continue using it.
I also got the matching footmuff to use with the CabrioFix which I found an excellent accessory, well worth the money - it meant J was warm enough in the car in his day clothes and just with the footmuff on, and because the harness goes inside the footmuff you can be confident the harness is correctly tensioned and not too loose on the baby because of the extra padding between them and the harness that you'd get by adding a winter coat.
As you expect to find with a child in a close fitting item such as the CabrioFix carseat, J got quite hot in it during the summer months so I also invested in a Summer Cover. This terry towelling fabric goes over the normal carseat fabric and means that baby remains cooler. Plus it's easy to remove and wash, which I did several times over and every time it came out good as new despite being the cream colour which a lot of people thought was really inappropriate for a baby carseat fabric colour!
The standard fabrics on the CabrioFix carseat can be removed for washing easily - and you don't need to mess with the harness at all to do so - which was another huge bonus for me. Maxi Cosi recommend handwashing fabrics at 30 degrees for optimum care, but I put them in our washing machine for a handwash cycle at 40 degrees and they came out brilliantly every time. I wash them then give them a fast spin in the machine and lay them on an airer to dry and they were ready for use again by the next morning.
Due to how tall J is, he became too long for the CabrioFix at 10 months old - his head was crowning over the top lip of the seat no matter how much I jiggled his legs to shift his bottom down and keep his head contained in the seat shell. In a rear facing carseat such as the CabrioFix, the head should not crown over the top lip of the seat, so at that point we needed to get the next stage carseat for him.
