Suitable for use with your Uppababy Vista pushchair, the PiggyBack offers your second child a place to stand if they're in need of a break. With a quick snap on and off attachment, it won't slow you down and it can be lifted out of the way when not in use. Non-skid surface prevents slipping. Suitable for use up to 22kg. Please note: this item is not compatible with 2015 Uppababy pushchairs.
