My son is 2YO, 24lbs, 34" tall. We have him RF in a Clek Foonf in my car and RF in a Britax Pavilion G3-70 in our other car. I have to say, we wish we bought another Clek. The Britax is fine, but for extended RFing, nothing beats the Clek. My son is so much more comfortable in the Clek than he is in the Britax. We've gone on many road trips (6+ hours) with him in both seats and we've decided to only use the Clek from now on. At 2yo and 34" tall, his feet barely touch the back of the seat and I think the recline from the RF base helps with that. In the Britax, the recline isn't as comfortable and he has to sit cross-legged, which is fine, but it's just much easier for him to fall asleep when in the seat. It just lends to much more peaceful car rides for us. All children are different when it comes to which car seats they find comfortable, but I do love that his legs are still straight in the Clek. Additionally, the Clek sits higher up and he's able to see out the window, which I also think lends to a much happier RFing experience for him. I think part of the reason why he fusses so much in the Britax is because he gets bored not being able to see out the window and only seeing the back of the seat. Another thing I love is the crypton fabric of the Clek. My son has thrown up in the Clek a couple of times and the clean up is so easy and there isn't any smell whatsoever. We love our Clek so much!
