An example apparatus includes a first axle extending from a left side support to a right side support, the first axle configured to axially rotate; a second axle extending from the left side support to the right side support and being substantially parallel to the first axle, the second axle configured to axially rotate, the second axle and the first axle being spaced apart. Each of the first axle and second axle include two or more lower support wheel assemblies and two or more higher support wheel assemblies alternatingly positioned along each axle. The higher support wheel assemblies have a larger diameter than the lower support wheel assemblies, and each of the lower support wheel assemblies and the higher support wheel assemblies are configured to axially rotate with a corresponding axle.
