j, these are the best buys for the 9-18kg stage. We looked at both and went with the maxi-cosi as it scored 75% as apposed to the britax which was only 70%. As i said before, the leg support definately swung it for us! We recieved it today, and had no probs getting it in the car. Hope this helps xx

Safety Standards : ISOFIX
ISOFIX stands for "International Standards Organisation FIX". It is a standard for installing child seats into cars and is intended to make fitting child seats quick and simple.
When cars are manufactured, ISOFIX points are built into them. Child seat manufacturers also build ISOFIX fitting points on their child seats. This will enable ISOFIX child seats to be simply plugged into the ISOFIX points in the car.
ISOFIX is an essential development because many people find it difficult to fit child seats correctly, and many surveys have found that a high proportion of the child seats are not fitted securely enough.
Most child seats are currently designed to be fitted by using a car's adult lap and diagonal seat belt (or sometimes, just a lap belt). However, car seats, seat belts, and their anchorages vary dramatically between different models of cars. Car seats have different shapes; some seat belts are much shorter than others, the position of the anchor points differs so some are further forward or have shorter stalks than others. All these factors make it virtually impossible to make a child car seat that fits all cars, and sometimes tricky to fit a child car seat correctly.
ISOFIX is designed to solve all these problems. The ultimate aim is that any ISOFIX child car seat you buy will fit your car simply by plugging it into the ISOFIX points.
The other benefit of ISOFIX is that it will create a rigid link between the child seat and the car to provide extra solidity.
All new cars are fitted with ISOFIX points, but it is important to make sure that any ISOFIX seats that you use in the vehicle are approved for it. It is not yet the case that an ISOFIX seat will fit in every car with ISOFIX points.
Many of the child seat manufacturers have a fitting list on their website that tells you which cars their seats will fit in, and you can click on the links below to take you to the fitting lists on different manufacturers websites
Your car's manufacturer, or a child seat retailer, may also be able to advise on the makes of seats which fit the ISOFix points in their vehicles. It is also best to visit a retailer with your car if you can, and ask to try the seat out in the car before you buy it.
To find out if your car has ISOFIX points, contact the manufacturer or dealer.
