A collapsible service cart that has four legs that are configured into two scissor arrangements. The scissor arrangements are joined together by a handle, a cross bar and two axles. The cross bar and first axle extend through both the first leg and the second leg. The second axle extends through both the third leg and the fourth leg. Both axles support wheels. A first platform is provided that is pivotably connected to both the third leg and the fourth leg. The first platform has a catch that can selectively receive and engage the cross bar. A second platform is provided that is pivotably connected to the first axle. Slides are attached to the second platform with pivot joints. The slides run along the first leg and the second leg as the service cart is changed between its open configuration and collapsed configuration.
