just out of curiosity, why is the base so important? never used mine
As mentioned above.
Makes life a tad easier not having strap the child in each and every time while reaching over to find the buckle.
Having to carry the stroller into the car with the child can be a little heavy at times. But allowing you to just drop and connect the stroller within 3 seconds give you a sigh of relief being able to drive off. Without the need to strap one in.
Have you ever had one that you're asking?
Now to have one in a second car would be convenient but it's not a must.
Being that there is a base in one vehicle, my wife will choose to use 1 vehicle over the other. But if there was a base in both she wouldn't mind driving either or.
They actually make a seat protector/cover which allows for you to stick the car seat directly on top of the seat without connecting it into any base.
