Prams /buggies

Hi everyone 😊, I wondered if I could have any recommendations on some lightweight prams for my 2 year old? I currently have a silver Cross one that I keep in the house and use sometimes going for walks, I do have a Cosatto woosh to keep in my car as the Silver Cross is pretty heavy, but I think I want to replace my Cosatto one as my son doesn't seem to sit that well in it, seems to slouch, and pushing the pram around the corner is pretty bad and it seems to drag round, it doesn't glide round corners like the Silver Cross. Just wondered if anyone mums could recommend any lightweight prams for a 2 year old and that's easy to push around corners?! Thanks 😊
