I used this Nuna PIPA car seat with the Twin Roo+ stroller frame for my twins, and it made getting around so much easier. The car seats click in and out of the stroller frame smoothly, and the whole setup is super sturdy. It's in like-new condition because I took great care of it, and it's perfect for anyone with twins or two little ones close in age. The stroller frame is very sturdy and easy to maneuver, even in tight spaces. Used in Like New conditions! A must need for any new twin parents! A very effective stroller and honestly a must have. Price is firm, all sold in one bundle! Nuna car seats ARE NOT INCLUDED. *added photo so you can see that they do snap on and off w/ joovy Nuna adapters that are included with this price. Local pick up only! Sold out everywhere!!!
