The Mamas & Papas ISOFIX base provides 4 years of ISOFIX safety for your child when used with the Primo Viaggio and Vito car seat. The ISOFIX base makes fitting your car seat quick and simple and helps to minimise the risk of incorrect seat installation. Using a oneclick system you can clip and unclip your Primo Viaggio car seat to the ISOFIX base. The Mamas & Papas ISOFIX Base also has an adjustable support leg that acts as an antirotation device in the event of an accident. The base has a sliding feature that allows it to be moved closer to the seat when installed and the one handed release lever helps you remove the base from your car with ease. All Mamas & Papas car seats are covered by a 2 year commitment guarantee.
