What are the ages and weights of your children? Some double strollers have seats that recline fully for newborns; others can only accommodate children from the age of 3 or 6 months. Side-by-side double strollers are best for twins or children of roughly equal weight. Tandem strollers and convertibles may be better for children of different ages and sizes. Check to see how much weight each seat holds and how much leg and headroom they allow for growing children.
What are your car seat transport needs? If you need your double stroller to be a complete travel system for two children, choose one that can accommodate two car seats or bassinets. Umbrella strollers typically aren't able to accommodate car seats at all, while jogging strollers may only be able to accommodate one car seat with an adapter. Your best bet may be a simple double car seat stroller frame until your babies are bigger.
How and where you will use it? If you need a double stroller for long, tiring outings, you may want to look at strollers with two equal-size seats. If it's only for outings to the zoo, museum or park where the kids are in and out, a detachable seat or standing ride-on board may work best, especially if one child is much older and capable of doing more walking.
How strong are you? Double strollers can be very heavy. Even the lightest double umbrella strollers still weigh more than 20 pounds, while some double jogging strollers close in on 40 pounds. Whether you live in the city or suburbs, you're going to need to lift the stroller and carry it -- into trunks, up the stairs or onto public transportation.
What is the size of your trunk or car? Most double strollers take up their fair share of space, even when folded. Closely examine the manufacturer's specifications and measure your trunk before buying -- some double strollers are difficult to fit in compact cars. Bulky jogging strollers often have removable wheels so they'll fit in tighter spaces than they otherwise would.
UPPAbaby's new double umbrella stroller, the G-Link (Est. $500), is hitting the market at the end of 2015 or in early 2016. UPPAbaby has earned rave reviews for its single G-Luxe stroller, which is the top umbrella pick in our single stroller report. The G-Luxe forms the basis for the G-Link, so we think this will be a very welcome option for parents who don't mind paying a premium for a fully featured double umbrella stroller. While there is little real-world feedback thus far, the stroller boasts a full recline, infant support pillows and a mesh foot enclosure that make it suitable for use from birth -- rare for an umbrella stroller. For added maneuverability, the G-Link will have four wheels rather than the standard six on most double umbrella strollers. The sunshades look much more ample than those on the competition, and the stroller will stand when folded. Even with the added bells and whistles, the G-Link will still be on the lighter end for a double umbrella stroller at 24½ pounds.
