A frame for cradling a rolled surface covering during installation onto a ground surface, including first and second spaced-apart end panels, a surface covering support base extending between the first and second spaced-apart panels and adapted for holding the rolled surface covering during installation. At least one lower roller extends along the support base between the first and second spaced-apart end panels at a level above the support base, and at least one upper roller extends along the support base between the first and second spaced-apart end panels at a level above the support base and is vertically spaced-apart from the at least one lower roller. The space defines a gap extending along a length of the at least one lower roller and the at least one upper roller through which a free end of the rolled surface covering is extended during installation onto the ground surface.
