I believe Britaxes position is that the seat must be in the reclined position when used rearfacing. However, adjusting the tension on the rearfacing tether should decrease the recline somewhat <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">
the carseat techs locally here have told me that my 3 year old's rear facing britax can be in the upright position and not reclined. i also recently put our 11 month old's rear facing britax in the upright position since he has been sitting up and crawling for months. i believe head control and core body strength are the biggest issues for putting it more upright.<br><br>
any mdc carseat techs want to weigh in?
I hadn't heard about installing it in the upright setting (not saying it's not true, I just hadn't heard that until now), but you can certainly adjust the recline angle, even with the car seat still in "recline mode." The 30-45 degree angle of recline is required for the first 3 months to protect a newborn's airway. After the first three months, it is actually safer for the car seat to be more upright (15-30 degrees reclined) than for it to remain at the 45-degree recline. More upright is always safer in regards to crash dynamics, it's just not safer in the first few months because of the newborn's airway.<br><br>
You can definitely reinstall your roundabout to be more upright. I find about 20 degrees to be the "perfect" blend of safety and comfort for the baby (more upright and it can be less comfortable for baby when asleep). But if your baby really likes to sit upright, you may find that a 15 degree recline works better for you.<br><br>
You should be able to install it less reclined (but still in the "recline" mode). When installing pull the carseat away from the seat bight about an inch or so. Then push down when the legs would go (not where the butt would go). Fasten seatbelt or LATCH. This should make the seat very upright. Then use the tether to adjust the recline to where you would like it.<br><br>
To answer the other question about installing RF in "upright" mode: yes, you can do it. Britax has said so. BUT, if you can install it in the recline mode that is prefered (there have been instances-with MAs- that the locking mechanism won't lock in the upright position).
