I lost my other stroller in an accident(along with one of my cats) 
so I bought the single wide (had double wide)  It is perfect, you can lock the front wheels so that you don't have to pick the stroller to move it. l like the cup holders, the double didn't have that.  'some complained they weren't deep enough.  I find the perfect.  I also prefer the wheels.  You pump air into them instead of those plastic ones make for a nice smooth ride.  Best of all the cat approves of it.
