Single or Double Mode Options for Newborns and Toddlers

The Mountain Buggy duet Stroller can accommodate up to 79 pounds of combined weight and is designed for use from birth up through age 5. Two independent seats mean your newborn can fully recline on one side, while your toddler is free to sit upright and watch the world go by on the other.

Travel and Storage Options Add Convenience

For newborns, the duet seats can go into a full lie-flat position. The duet is also compatible with the duet carrycot, as well as with the Graco Snugride infant car seats by use of a seat adaptor (sold separately). Because the duet can handle up to two infant car seats at once, it provides you with a seamless transition from vehicle to trail for one child or twins. As a bonus, the duet’s generously sized underseat storage area holds up to 11 pounds of gear.

With the use of the Joey Clip-On Tote Bag (sold separately), the duet converts to a single buggy with plenty of storage. This two-in-one bag features a removable (and recyclable) internal bag that sits within a durable, polyester external bag. The Joey is also interchangeable with the duet and duo, providing you with additional space even as your family grows.

Slim Single-Stroller Width and Pedal Brake

The duet has a lightweight aluminum frame and a compact design with the same 25-inch width as the single Mountain Buggy Urban Jungle stroller. Its 10-inch air-filled tires maneuver smoothly around tight corners, up and down curbs, and through narrow doorways. They also tackle uneven or bumpy terrain with ease. When it’s time to stop and chat, the wheels lock securely in place with a pedal brake.

Infinite Position Recline and Five-Point Harness

The Seat Performance System features an easily adjusted, infinite position seat recline between upright and lie-flat. A one hand adjust, twist and slide five-point seat harness provides a range of height positions for a secure, comfortable fit. For easy in and out, the grab bar detaches.

Adjustable Handle Bar for Comfortable Pushing

Whatever your height, you are sure to find a comfortable handle setting for pushing the duet. The handle allows for multiple adjustments and a safety wrist strap ensures a secure grip. Enjoy greater flexibility with one-hand control as you steer through busy malls, subway platforms, or the playground.

Easy-Fold Design for Storage

You can quickly fold the stroller down to a 43-inch height in one smooth action thanks to its slide-release mechanism, which features a secondary lock assembly for added safety at the riser plate (foot rest). When ready to store the stroller, the frame locks securely with a clip and strap on the handle. For the most compact fold, remove the wheels–no tools required.

Adjustable Sun Protection

The duet’s fully adjustable and individual hoods provide shaded coverage from the sun in most angles or directions of travel. The flick-out visors keep the sun away from your child’s eyes.

The duet is also easy to care for thanks to wipe-clean 100 percent polyester fabric coverings that remove quickly.

Safety and Warranty Information

The duet has been rigorously safety tested and is certified compliant with EN1888:2005, ASTM F833-10-USA, AS/NZS 2088:2010, CPN8-AUS/NZ, and SOR/85-379-Canada standards.

The Mountain Buggy duet Double Buggy Stroller is backed by a manufacturer’s limited one-year warranty.
