Correct fitting of all car seats and boosters is of paramount importance to make them most effective in the event of an accident. Not all car seats fit all cars and it is important to check for fitting suitability on all cars you intend fitting the seat to, as well as re-checking if you change your car. Always read the instruction booklet which comes with your car seat to achieve a safe and correct fitting, retaining the guide for future reference. We recommend fitting your car seat in advance of first using it. We recommend that babies shouldn`t be left in Group 0/0+ car seats (infant carriers) for prolonged periods. Suitability: Please make sure that you check the car seat you choose is suitable for your car before ordering. Some of our shops offer a car seat fit test, where a Nursery advisor will test the display model in your car to check that it will fit properly. Please contact your local shop to see if this service is available. Alternatively, please contact the car seat manufacturer who will be able to advise whether their model will be suitable for your car.
