Which strollers have toddler seats?

I am looking for a single with some sort of add on toddler seat. Basically, I want something narrower for use in the mall than a traditional SBS twin. I'd prefer something with a smaller fold as I have a sedan so trunk space is limited. I've thought of the Valco or the E3, but I'm worried about the bulky fold. Any other options?

THANKS!!!

Do you need swivel wheels or would a fixed wheel stroller do? The old Emma models like Brasilia/Coronette and Husky had the toddler seat (adding to the front on the bumper bar). You can find these gently used though as they are discontinued and no longer sold in North America

The fold on the E3 is very compact. You do need to remove the extra toddler seat first - takes about 5 seconds.

I have a 1yr old & 3yr old. My 3yr old is now 30lbs and too big for the toddler seat but for the first year of my daughters life - the toddler seat on my Rapid Swivel Jogger was exactly what i needed when taking the two of them to the mall and stuff.
