Overview
Description
Designed for the Mockingbird Single-to-Double Stroller, the 2nd Seat Kit allows you to add an additional seat to your Stroller and choose from tons of useful two-seat arrangements. Mockingbird’s top and bottom seats are also interchangeable, so you can use both of them with children up to 45 lbs.
To use the 2nd Seat Kit with an infant, pair with Mockingbird’s cozy lie-flat Bassinet, the practical space-saving Infant Seat Insert or one of their Car Seat Adapters compatible with over 40 different infant car seats (sold separately). For twins, it’s recommended to use the 2nd Seat Kit with two Infant Seat Inserts or with two identical car seats.
This updated version of the 2nd Seat Kit also includes a pop-out visor on the front of the canopy for additional sun protection and seat straps that automatically adjust to child’s height with one quick pull (no more manual re-threading).

I purchased this for my daughter who is expecting her 2nd child in April. It looks great and appears to fit well, but she hasn't used it yet, so I can't say much more.

Works Reall Well for two kids
The second seat is a great add for the Mockingbird 2.0. It allows for plenty of space and it easy to remove and install. It is obviously heavier with a second kid, but the stroller holds up well with two kids and maneuvers well.

The seat is very similar but the new buckles are a downgrade
The seat itself is quite similar and I love that the awning goes down further to protect from the sun. But the buckles... so terrible. Major downgrade from the previous model. The buckles are unnecessarily complex and don't stay buckled. Can easily bust them open without pressing the button which is a hazard. I haven't reached out to mockingbird yet but will be and will update said review accordingly.

Perfect for my daughter
Bought it for my daughter as she has a 2 1/2 year old and 2 month old. She loves it. Obviously she already had the carriage, it was very easy to install the second seat/ support for infant carrier/car seat. Also added the accessory pieces to carry drinks, keys, etc…

Absolutely love this stroller especially since it adapted for us from 1 to 2. I often get asked about the stroller when were out and always recommend it. Rides like a dream. My fave stroller and I have 4 kids
