• and
• a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position,
• wherein the front seat attachment is configured to releasably connect to and support the front stroller seat in either a forward-facing configuration or a backward-facing configuration,
• wherein the front seat attachment is configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels;
