Britax B-Safe Extra Base Infant Car Seat


Car Seat Base

 from Charleston, SC– Verified Buyer

This base works as expected - the car seat snaps in and out easily. It does slide a bit on leather, so we put a protector pad or towel under it to secure it.

Great carseat base-- easy to install

 from Rockville, MD– Verified Buyer

We got this as a 2nd base go into the 2nd car. According to my husband it installs pretty easily (once you've consulted your car manual). We also took the car and installed baseseat to the county for an inspection and because of the ease of installation and my husband's attention to detail, we passed with flying colors. Without the baby in the seat (we are a few weeks from the due date), it's pretty easy to click the carseat into the base and out. Wayfair price was the best online at the time I ordered.
