Keep Chaperone or other infant seat?

I'm thinking of what to put baby #5 in come May. We have a Britax Chaperone from 2009 (bought in 2011 and used with one baby). It's going outboard captain's chair Honda Odyssey 2011, driver side.

Keep...or?

Is the Aton REALLY lighter to carry once you stick a growing baby in it?
Does the foam (and air by head) on the Prezi impress anyone?

At this point us going anywhere is total chaos, my back is not good, and I want something easy on me. Simple as possible! I wasn't sure if there is anything out there I'm missing. And the longer baby is in infant seat, all the better to click him/her into a stroller through winter.

The reality is that this baby will spend a lot of time in the carseat as I get the other kids where they need to go daily, so it's tempting to want something without the known harmful flame retardants as I already went through the trouble minimizing those in the crib environment. I think Graco is on board now with that? And Britax should be by the end of the year.

(Eventually he/she is going into the Orbit toddler but we won't have the stroller for that).

My main love of the Chaperone is the foam in baby's headwings that almost hug the head (and my old Companion seat was even better). So it'd be hard to give that up unless others offer it, too.

p.s. My babies tend to be a bit under 10 lbs, if that helps.

Bumping because I am interested in the answer!

I would use the chaperone and save the money I'd spend on an aton for a good ergo or boba

I don't have input on what you should do, but wanted to let you know babies r us has Atons in stock, online, for 199.99 plus 20% off so it would be 160 plus free shipping. It is only in the shadow color, but thought you might want to know of the sale.


****Sorry just read the fine print, it is not 20% off, but still not a bad deal.****

I've only played with an Aton once, briefly but I want one. I had a chaperone with ds3, it was heavy, as you know, it didn't seem that much heavier at first, but as ds3 got heavier, it was easier to carry him in the keyfit. The chaperone was also top heavy and every time I set it down empty it flipped backwards, just annoying to me. I like infant seats, they're fun to play with I currently have a sr35 and kf30, but am considering going with an aton this time. I liked the look of the prezi, but usually end up disliking dorel seats so I think I'm going to skip that one.
