Taurean - I found when I put my 19mo in the toddler seat, her head poked just above the top of the seat. Like.. only half her head. That meant that I could recline that seat the lil bit when she fell asleep.. but she still slept comfortably none the less. The vibe has a lot more comfy padding than the sports... so more comfortable. Personally, the ease of the brake, weight of the overall pram and the comfort of the seats far out weighs if the seat is smaller.

Lisa - Granted I've only used it once with the toddler seat down bottom and had my 4.5yo up top, but I never kicked the back of the seat once.. But i'm tallish and have long arms, so may be standing back a bit. I'm bout 5'9. You can adjust the handle.. that might make a difference?

Dannim - i'm glad I'm not the only one. My DH has said to make sure the wheel is flat.. and that the basket underneath kinda folds into itself.. which i have.. i'm sure as time goes it will "loosen".

overall.. luv the pram!
