4 vs. 3 wheels:
- 4 better maneuverability
- 4 generally more stable - especially when going up/down from trams etc.
- 3 wheels - fixed - better for running/jogging/exercise
- 3 wheels rotating - watch out for those - they have good turning, but can tip easily if you lift them on the single wheel.
- 3 wheels generally longer frame than 4 - wheels
Single handle vs. 2 handle-bars - go for single handle - much harder to move a buggy with separate handlebars, e.g. when on phone or going in out doors etc.
Big wheels better than small wheels.
Buy more expensive - usually has better components and bearings
We had:
Jane
Bugaboo chameleon
TFK
and 2 cheap "umbrella" ones
Bugaboo by miles. Only downside was that it isn't that small when folded. but when up and about, v small and easy to handle, so not great for travelling/flying - we got the umbrella ones for that.
When trying one out in the shop, ask for a couple of some weight to put in the seat to see what it is really like.
Ask in the shop what matches with what in terms of car seats. Bugaboo works with Maxi-cosi. You usually only need a 3-point harness for car-seats or the isofix system which is standardised. So really it is about the match of the car seat to the buggy system you choose.
Oh. And have you thought about where your baby is going to sleep?
Hint: [Stokke Care changing table & infant Sleepi bed [Basel]](http://www.englishforum.ch/items-sale/257192-stokke-care-changing-table-infant-sleepi-bed-basel.html#post2625852)
I have the maxi-cosi-Bugaboo baby seat adapters that we don't need and will throw them in for free if you are interested in the bed...
Good luck with the baby & enjoy!
