Hi there, Just to say the roll up tray thing is Blooming Marvellous which is quite handy. Oh and we also have a Tripp Trapp which I love because it takes up so little space, had a decent footplate so pumpkin is comfortable in it for quite a while and she can eat at the table. Luckily it was a present from my Mum because it is a bit on the pricey side.... Oh, and I also don't get how a car seat would help your mealtime routine!
