for the reversible car seat in my car, and the capsule in DH's car, we got the Red Cross to install for us (we hired the capsule through the Red Cross SA). I wasn't keen on installing these ourselves. This changed with when we did the forward facing seats, my car I got a family friend to do it for us (we got the seat off them to start with) and the Red Cross installed DH's car seat when we returned the capsule although it was still reversed. I did the turn for his car, having read the instructions several times and watched how my car seat was installed so I was fairly confident about it. I've since had to take out the car seats to get stuff into each car without DS around so I've re-installed in both cars. BUT I would still get a professional to install the reverse facing seat/capsule, just because baby is such a precious cargo.
