Why We Love It
The 2nd Seat Kit 2.0 lets you expand your Single-to-Double Stroller 2.0 so you can stroll with two kiddos.
It takes less than a minute to switch to double mode, and you can mix and match between over 22+ seating configurations to find the best setups for your family. And with an impressive weight capacity of 45 lbs in each seat, you’ll be able to use your two-seat setup for years to come.
Features & Use
The 2nd Seat Kit 2.0 comes with one seat, a set of upper adapters (to raise your 1st Seat and make room for the 2nd), and a set of lower adapters (to attach the 2nd Seat).
The adapters can be installed in under a minute and removed just as quickly, so you can easily switch from single to double mode and back again.
Compatibility
The 2nd Seat Kit 2.0 is compatible with the Mockingbird Single-to-Double Stroller (both the original and 2.0 versions), but cannot be used with the Mockingbird Single Stroller. If you're unsure about which model you have, feel free to contact our product specialists.
Strolling with an infant + toddler:
To stroll with an infant and an older kiddo, you’ll need the 2nd Seat Kit to make room for two riders, as well as one of our three infant accessories (strongly recommended until your newborn develops head and neck support). You can choose from Mockingbird’s cozy lie-flat Bassinet, the practical space-saving Infant Seat Insert, or one of our convenient Car Seat Adapter, which is compatible with over 35 popular infant car seats (all sold separately).
Strolling with two infants:
For twins, we recommended using the 2nd Seat Kit 2.0 with two Infant Seat Inserts or with two Car Seat Adapters.
Age, Weight, & Height Guidelines
Unlike other two-seat strollers, our top and bottom seats are identical, so they have the same weight limit. You can use both seats with children up to 45 lb. The maximum headroom from the seat to the canopy is about 20".
Care & Cleaning
To clean, wipe with a damp cloth and mild detergent (if necessary).
The seats fabric is machine washable, but most stains can be removed by wiping clean.
See a few of our favorite setups
You'll often hear about how many configurations you can create with various convertible strollers, but what really matters is that they work for your family. Here are some of our most popular double mode configurations:

Two Seats
Most strollers' add-on seats have a lower weight limit than the included seat, so parents typically have to put the smaller child in the lower position.
Our 2nd Seat is identical to the seat included with the Stroller, with a weight limit of 45 lbs for each seat when used in double mode. Both seats can face either direction, giving you four different two-seat configurations.

Bassinet + Seat
Many double strollers with Bassinet attachments require you to put the Bassinet in the lower position, so your baby is riding just a few inches above the ground.
Our Bassinet goes in the top position, so you can easily see and care for your infant, while your older child goes up front, and can face forward or toward you.

Twin Configurations
The Single-to-Double Stroller is a favorite among twin parents. To stroll with twin infants, you can use the 2nd Seat Kit + two Car Seat Adapters or two Infant Seat Inserts.
As your twins get older, you can face both kiddos forward, both toward you, facing each other when they're getting along, or facing away from each other when they're not!
Reviews
"Customers say the 2nd Seat Kit is a game-changer for growing families, allowing the stroller to convert seamlessly into a double. Parents appreciate that installation is easy, there are multiple configuration options to keep both children comfortable, and it feels sturdy and easy-to-maneuver even with two kids on board. One drawback mentioned in some reviews is the additional trunk space required to store the stroller in double mode."
