Isofix bases

— products designed for installing car seats on Isofix mounts. However, this category can also include bases with other installation methods (e.g. fixed with the regular car belt).

The base is a quick-release mount for the seat. Such a base is installed in the car (usually on Isofix brackets) and can stay there permanently, while the seat itself can be easily removed and installed as needed. This increases convenience and gives parents additional opportunities: for example, asleep in the car baby can be brought home directly in the seat and already there to transfer to the crib, so as not to disturb unnecessary time.

Note that the bases are usually made for specific models of seats. Actually, bases for seats are most often initially supplied in a set, but sometimes there is a need to buy such an accessory separately — for example, in case of breakage of the set base, or if there are several cars in the family, in which it is necessary to alternately install the seat.
