Bought the seat because it has flat position.
I've made mistake with our first baby, when the seat we got was only in sitting position.
Concord Rio is very comfortable, nice looking seat, baby loved being in it. Never had to wash any of the liners, because I always put the muslin under baby's head.
The bad points are:
- too heavy
- too bulky
- never used the carry handles, because it's not possible - You need to live in a palace to have very wide corridor to be able to walk with this seat holding it next to You
- never used sitting positions other than flat and slightly up for baby to see what's happining around, because the seat is up to 6 months and that's when most of the babies start to sit
- too expensive to buy new, but I've sold mine for half of the price on ebay.
Would recommend to someone who has a lots of space, so the seat stays in one place or You don't need to move it a lot. Or, get it second hand, so then You pay much less.
Otherwise buy alternative - there are seats for up to 12 months.
