Also check reviews online after you've tried them out yourself, turns out one i really liked had wider back wheels than standard and people struggled in shops and getting through doors (i think it was the mothercare orb, I think)
Also if you can get your husband or mother or MIL anyone who will be pushing the pram to have a go too to see if they are comfortable with it. My husband hated certain ones which I loved but now he loves pushing the pram cause he helped picked it.
We went for the Joie chrome with carry cot and a carseat which is interchangeable too. Very cheap on offer in mothercare and its excellent, we are out walking everyday and its doing great. The handle is extendable (my husband is very tall) has swivel front wheels which I highly recommend and a large basket. Its a dream to collapse going into a car. I wanted practicality as we dont drive and would be using the pram a lot. I knew id be out long periods so needed the carry cot, I'm definitely getting my wear out of it though so I don't mind.
Good luck with deciding!
