The Maxi-Cosi 2WayFix Isofix Base can be used straight from birth up to approximately 36kg (79lbs) and is fully compatible with the Pebble, Pebble Plus, Cabriofix and 2WayPearl Car Seats. This isofix base allows children to travel in a rearward-facing position for even longer as the base can be easily installed into your car using the isofix connection points. Featuring an adjustable leg support, it also adds an additional level of security to the installation of your car seat; while the click and go release button allows you to simply release the base from your car whenever needed. Featuring a visual and audio warning system, the Maxi-Cosi 2WayFix Isofix Base offers you reassurance and confirmation that it has been correctly installed for optimum security. The warning system will show you that the seat is securely connected to the isofix anchorage points, that the support leg is correctly positioned and also that the car seat is correctly attached to the base for a three-tiered confirmation process. There are also additional warning lights to provide you with a handy reminder not to place the seat in front of an active front airbag if in rearward-facing mode and also to only change to forward-facing mode once your little one reaches a minimum of 15 months old. The Maxi-Cosi 2WayFix Isofix Base also features a unique rebound bar that will provide extra stability and prevent against any upward movement in the event of a rear impact. When not in use, the adjustable support leg can be folded away for added convenience. We recommend that you check that this isofix base is compatible with your vehicle before purchasing.
