Pushing a pair or soon expect to be? This tandem double stroller has a low-profile frame, toddler seat, and two sets of adapters that allow it to convert from a single to a double or twin (an extra seat or bassinet will cost an additional $179 each). It offers up to 23 configurations and is more compact than other double strollers. It also boasts an all-weather seat, dual suspension, one-touch brakes, an easy release to its five-point harness, and a removable, extendable UPF 50 canopy.
