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).

Second seat

2nd seat kit is it
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

very good!

Really Heavy
It is easy to assemble and take a part but if you go on walks often it makes the stroller a lot heavier to move around. We ended up finding a jogging stroller was more worth the money in the end.

2 under 2!
Great product for 2 under 2 like us! We break the stroller completely down. Even taking off the small attachments when loading in the car. This stroller is literally a limousine, but so much easier if your solo parenting.

Nice for city and never breaking down
It glides nicely in flat terrain. Hard to get over bumps when you have to push down on the handle to lift the front. I bump the front into a lot of things. Easy to assemble though. I like it but don't love it. We never break it down so it works for us in the city. If I needed it in my car I don't think I'd keep it because it's bulky.

Must have with 2nd child.
Necessary for 2nd child. Bought this alongside the bassinet. Makes going out so much easier. We bring the baby carrier alongside so we have options. Have not used the 2nd seat yet but we know it’s going to be great when the time comes.

Second seat- love it!
Having the second seat has been so great! We are an 'outdoor' family and our walks save us during the withcing hour stretch from dinner to bed time; so having this to accommodate both kids, while not taking up too much width in the road and storage area is so amazing!

Second seat kit
Works great! Only 4 starts because the clasp is a pain to connect, but otherwise we love our mockingbird and the attachments we have for it. Fits my 4yr old and 2 yr old perfectly.
