The BEST Carseat Ever!!!

About Me Parent of Two or More Children
I was looking for a convertible carseat for my 9 month old who was getting uncomfortable in his bucket carrier seat. The car seat I was going to order was out of stock and I didn't want to wait. I ordered this one and it was the best decision I could have made. It took no time at all to install it, the instructions were so easy to follow. My son LOVES it, it's cushy and the cushions on the straps are so easy to adjust and move to wear you want them. I would absolutely recommend this to a friend!

About Me First Time Parent
I love this car seat! It took me a while to decide between this one and a Graco but I am so glad I went with the Britax. It was super easy to install and the recline and hight adjusters are so convinient. The Britax is very good quality and very safe. It has versa tethers and steel bars.. The Graco one we looked at seemed flimsy and didn't offer much support. All plastic... The infant support pillow it came with is super soft and comfy. The cover is also easily removed so it can be washed. Best purchase I've made. I also loved that thanks to Diapers.com we had free shipping and it arrived the next day. How awesome is that?!
I like this carseat

I am a huge Britax fan, mostly because of ease of use and installation. This one fit the bill. I have a Boulevard for my son but this Marathon was a great deal, and I honestly can't tell the difference. As always, it was easily installed with the LATCH system.
My 14 month old is very happy in it. If I had only one complaint (although, it's not really a huge deal) the fabric on this seat is not a soft fabric, it's more like a stroller fabric which is easy to clean/wipe (big plus) but first thing in the morning it's pretty cold to the touch. This will likely be nice in the summer. The pattern is beautiful and I'm definitely happy with this purchase.
