Supportive lightweight pushchair

I need a lightweight pushchair, with a hood and that reclines enough for a one year old to sleep in. I have a silvercross pop and for my other daughter it was great. This baby though is little and dumpy (god bless her!) and the seat when sat up fully is not supportive. She falls over to the side and her legs look uncomfortable. She fidgets all the time. Ideally I don't want to pay more than £150 as I have a pram I use all the time and this is mainly for the school run so must fit in the boot of a clio. I just wondered if anyone has any preferences on good, supportive pushchairs. Thank you
