Kerstin Degner –
Love, really like the head support
Amanda –
Very easy to install, made seat appear much more comfortable.
Elise Ketaner –
I only took one star off because I think it’s a total load of you know what that this set isn’t included with the car seat. My twins used this during infant and toddler. The seat cushion is nice because then you can just pull that out and wash it instead of removing the whole dang thing for smaller messes. Also head pillow is going to work for a long time. Good for road trip sleeping.
Side note: also spent $25 on the foam inserts that go with the rear facing option to save space for the front seats.
All this being said I have twins so add up the car seats, infant seat packages, and the foam bases and I spent crazy money. I do love the set up and my kids and they feel safe and comfortable.
