You really need to try them on yourself with your baby (don't use the fake baby they provide), every hipseat fits every mum differently, you won't know until you try it on. I went into AEON and had my eyes on Sibii because of its storage, after trying it on, it wasn't comfortable for me AT ALL! Then the sales person tried to sell me Todbi, which I never heard on, tried it on, loved it!
