Hi L.,
We have the same problem. I e-mailed Chicco directly about a week ago to ask them about a tandem stroller (front and back) that fits the car seat. Here is what they told me:
Thank you for your inquiry. We will be introducing a tandem double stroller that will accept 1 or 2 of our Chicco car seats. This should be introduced approximately in Spring of 2010. We suggest that you check our website at www.chiccousa.com for updates on this product.
The Contours Options Tandem made by Kolcraft will accept one of the Chicco KeyFit infant car seats. We also suggest the Joovy Standon Caboose or the Joovy Big Caboose. These Joovy products will also accept one of the Chicco KeyFit car seats. Our car seats can be buckled into these strollers. We hope you find this information helpful.

L.- If you are looking for a side by side stroller, you may want to do more research, I was only interested in the tandem- good luck! :)
