I need a cheap as chips highchair BUT it has to be sturdy and have a tray - is this possible?

Title says it all really, does this exist or do I have to spend a fortune?

Same here - much better than the expensive one I had with DC1. Just repeating what everyone has said really. Legs and tray come off easily (it is easier to cart around than my travel highchair that straps to seats). I take the tray off sometimes and wash with my washing up. Most of the mums I know have one.

Ikea Antilop. And you can easily dismantle it to take away on holiday!
