manoeuvre and fold up. DP & I got the bassinette attachment as well because I wasn't comfortable that the main seat doesn't fully recline. Even if we only use the bassinette for a couple of months I think it is worth the extra $130 and I also figured it would be good for bubs to sleep in when out and about or even at home.
I also like how you can turn the seat around so bubs can be facing you or facing away. I liked this option over some of the prams where the handle moves back and forward and risk bubs fingers getting caught.
With the wheels, I actually prefer the solid ones over the pump up ones. All my friends which pump up wheels have complained about how they are always pumping up the wheels.
When we were looking at prams/strollers in the stores I noticed that ALOT of them had the problem of wobbly wheels. Since most of them can be detached, I think they just don't get put back on properly when people try them out in the shop.
