I know this is probably a silly question, but can you somehow, safely, add padding to a carseat? looking at the scenera as a 3rd carseat for my mom's car for when she occasionally needs to take the little one out while i am working.
You're not supposed to put anything between the kid and the seat that dosen't come in the box with the seat. You don't know how it may change the way the seat works in a crash and you don't want to test it on your kid KWIM?
Kristy said it! Nope, no adding things to car seats that aren't crash tested with them. There are some more padded seats then the Scenera that can often be found for a decent price. The Safety First UpTown is one of them that is often recommended as a "step up" back up seat. Best of luck mama!
No, unfortunately you cannot. Check out the Safety 1st Avenue. It's very similar to the Scenera. It's lightweight and a good travel or backup seat but it has taller top slots and much comfier padding. Plus EPS foam. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up">
