Foundations triple stroller.
You can find more detailed information on it by looking at their website.
It's in great condition and has always been stored inside. I use it for daycare and I went back to a double stroller. It's easy to push, fit through doorways and it actually folds up pretty compact. Each seat has its own canopy, the seats recline and a huge storage area underneath. Good for multiple ages of kids. The green color really stands out to cars when you are out on walks. I really like it but no longer need a triple. It's great for a daycare or someone with multiple kids to transport.
