HI!

I need to buy a convertible carseat for my 3 month old who has just hit 8kg....

I'm looking at the Hipod Madrid or SIenna.
Has anyone used these before?
They look good and did well in the last tests and are so much cheaper than most of the Safe n Sound ones.
Just interested to know what you think of them and if they are a tall seat?
How long did your bub last rearward facing?
and forward facing?

Sorry for he ramble and thanks in advance!
