Excellent collapseable triplet stroller made by Triple Decker Triplet Stroller, Inc. It fits Graco and Evenflo infant car seats. Great condition. Used it for our triplets and it was a life saver. We could easily take the car seat off the base from our car and snap it to the stroller within seconds. Has storage underneath. See the link below for additional info and pictures.
Thx!
