A tandem stroller is best for children of different ages, though there are a few that are good for twins. In tandems, kids are positioned one behind the other. Some tandems have two traditional seats; others have a full seat with a rear bench or stand-on platform.
The Joovy Caboose Ultralight Stand-On (*Est. $230) gets rave reviews for being one of the lightest doubles on the market at 21 pounds and one of the easiest to maneuver and fold. It fits through tight spaces with ease. It comes with one full seat in the front and a smaller bench in the back for kids to sit or stand on; plus you can also purchase the Joovy Caboose Too Rear Seat (*Est. $70), which can be attached over the bench to provide a second full-sized seat. This stroller comes packed with handy accessories like a parent organizer and snack tray that are often sold separately on other doubles. Even a universal car seat adaptor is included.
The Baby Trend Sit N Stand Double (*Est.$140) is also a stand-on but comes with two reclining seats. The rear seat can be converted to a jump seat and standing platform for an older child. It can take two car seats, accommodating Baby Trend, Evenflo and Britax models.
For those who want more of a traditional tandem -- with two full seats and no stand-on options -- the Chicco Cortina Together (*Est. $300) is a favorite with parents of twins or closely spaced children. It's one of the few to accommodate two car seats (Chicco KeyFit/KeyFit 30 models), converting to a full twin travel system. Though it weighs in at a whopping 34 pounds, reviewers generally praise its maneuverability, sturdiness and easy fold.
