Sorry what is the function of this base? I seems like a baby car seat

it's a base that a car seat snaps in to. that same car seat is removable and we can use with our britax stroller. it's part of the overall britax b-safe/b-agile travel system

The car seat snaps into the base. The base stays in the car while you take the baby in the carseat inside

The base is separate from the seat. The seat can lock into the base, but it can also lock into a Britax stroller. A seat comes with one base. The base has a quick release handle for easy unlocking and removal of the seat. My wife and I bought a second, separate base so that we could lock one down in the back seats of both her car and my SUV. This allowed us to quickly unlock and lift out the seat (which has a stowable carry handle) and transport our son, rather than having to unstrap him or strap him every time we exited or entered a vehicle. Note that the base can lock to a seat by either of two methods: via the seat belts; or via hooks and latches, if your vehicle has anchor brackets. (If your vehicle is so equipped, your vehicle owner's manual will have a section on this; more than likely, you will have baby seat symbols marked near your anchor points.)

The base is what you "attach" to the car. You then remove the carseat from the car with one push of a button and you don't ever have to undo the base unless you need to put it in another vehicle. I love this system and it was simple to set up.

This car seat is a convertible and does not leave the car once installed, like an infant car seat does. There is no seperayte base, the car seat is all one unit.

I bought it for that reason too but honestly... No. It's not like an infant base and if you have a small child you have to think about where to put them while you are trying to switch it between cars. It's not light. We have found it easier to have two separate carseats for our vehicles. I still love this seat, though, so it's in my car (which is used daily).

Infant carriers have bases. This is a convertible car seat, you leave it in the car.

All infant seats should come with a base. You just have to purchase additional ones.

There really isn't a base for this seat. If you want to move it between vehicles you have to disconnect it completely.

I have the Keyfit base for my grandson's carseat and find it very convenient. I did research the Nextfit in order to answer you question and my understanding is that the base is not detachable on the Nextfit. They indicate it is not a carrier car seat like the Keyfit. I got this info on www.chiccousa.com" and clicked on FQA. Look at the question "Should I use the Keyfit first........" It should answer your question. Hope this helps. Sorry it took so long, but I am busy babysitting and don't get to check my email as often as I should.

There's a release button on the sides of the carseat where it attaches to the adaptor that you press before lifting it. It is a similar mechanism as the one for the base.

This model would fall and shift, there is nothing to hold it in place except the child's carseat. Good luck finding something that works for you!

With the base. The carseat is really heavy, though! I like it, because that means it's sturdy...but yeah...arm workout galore!

If you're buying the seat it will come with the base so you don't need to buy this too but an extra base is useful if you plan on transporting the baby in more than one car-it eliminates having to continually take out and resecure which is not always an easy task

The base is attached to the car seat unlike the infant ones where it snaps in.

The base is made to be used with a latch system and traditional seatbelts, and is very easy to use either way. The carseat itself can also be seat belted in without the base if needed.

The base is screwed to floor, wood screws. The top attaches to bottom of your seat with screws, universal location. It will work

No base. It is not detachable, and you cannot carry your child around in it. It attaches into your vehicle like a toddler seat.

I have twin girls and my husband and I bought two chicco infant car seats that came with bases. The bases stayed in my car and he used the seat belt to secure them when in his car. I have since bought two foward facing seats for my car and the infant seats are still in his car with the base. We will have to buy forward facing soon for his car. So we have bought 4 so far and will need to buy 2 more. I suggest you buy two convertible seats, and let them buy 2 infant seats if they want them.

If by base you mean the rectangular shaped area at the bottom of the car seat then no, its part of the seat.
