Should I go with option 1, I've never owned Safety First baby gear so I'm not accustomed to it. I'm not sure if it lasts, if its safe, comfortable, easy to install, but it looks like a great seat.

Option 2 is what we did with DS#1 when he was done with his infant seat we got him the Scenara and he was able to RF until 15 months when he hit the weight requirement to switch and I'm glad I did switch him because he was able to undo the straps very easy. But we LOVE the nautilus seat. Hes almost 5 and still using the harness. He just hit the weight requirement for a booster but I feel comfortable having him in the harness still. We're familiar with it so thats a plus over option 2.

Walmart has both at a similar price. Option 2 comes in a bundle.

after my sons safety 1st car seat was recalled i refuse to buy any safety 1st car seats so my vote goes to Graco  

We have the complete air and I love it. She rear faced until 2 and a half and seems to still have plenty of room for the harness and she's 3. But we are buying a graco nautlius too (she's almost out grew her myride).

I did have issues installing the complete air rear facing with a seatbelt and it took up a lot of room.

I will never buy anything except a Diono Radian ever again. Nothing else will RF as long. My 3yo can undo his clasps, but with the mirror I can see when he does it and pull off and fix it or tell him to fix it (he usually does).

That being said, i trust Graco MORE than Safety 1st, but its definitely not in my top 5 brand choices at all.

The radian is just too large for our car but I do like that seat.

We love our Complete Airs, Daphne just moved into hers last month.
