Hi Tricia,

I can't really help either as I purchased the Phil & Teds - Vibe. My criteria was similiar to yours (I wasn't fussed about 3 wheels or 4).
Our pram is very light weight, we purchased the cocoon also, the handlebars an be moved into 3 seperate positions and the seat is reversible too.

Good Luck with your decision and all the best for the rest of your pregnancy.
