1. Britax Boulevard Clicktight Convertible Car Seat

The Boulevard is one of the lightest Britax convertible car seat options, weighing 29.4 lbs. It has a steel frame that absorbs impact but still comes in lighter than the Britax Advocate. 

The Boulevard has two layers of side impact protection, an improvement from the previous model.

Car seats can be difficult for moms to install, but the weight of the Boulevard combined with the ClickTight installation system makes it quick and easy. 

You don’t have to uninstall the seat to remove the cover, but if you did, it would be simple to do.

Lightweight seats sometimes sacrifice comfort, but the Pria Sport 2-in-1 has premium flame-retardant-free fabrics and padding to keep your baby comfortable and safe.
