Lightweight dolly assembly

A dolly assembly comprising:

• a base at least partially formed from a substantially flexible material and including oppositely disposed surfaces,
• said base comprising an inflatable construction including an at least partially hollow interior structured to retain an inflating fluid therein,
• a plurality of pockets extending at least partially through said base in communicating relation with at least one of said opposite surfaces,
• a plurality of casters each at least partially disposed within a different one of said plurality of pockets in connected, supporting relation to said base,
• at least some of said plurality of pockets and corresponding ones of said plurality casters disposed in a predetermined spaced relation to one another,
• said substantially flexible material of said base having sufficient structural integrity to maintain said plurality of casters in said predetermined spaced relation to one another,
• a reinforcing member connected to said base and disposed and structured to facilitate maintenance of said plurality of casters in said spaced relation to one another, wherein said plurality of casters collectively define a primary support for an object disposed on said base,
• said reinforcing member being formed of an at least partially flexible material having sufficient structural integrity to further facilitate maintenance of said plurality of casters in said predetermined spaced relation to one another, and
• said reinforcing member comprising a mat including an at least partially planar configuration dimensioned and configured to extend along at least a majority of the transverse and longitudinal dimensions of said base.
