I purchased the original table without the wheel feature (wish this one had them, though) to use for my Viking 1+ machine.  The smaller cut-out is just right for the 1+ (but too small for the Designer).  With the insert in the lowered position I needed thin cardboard and styrofoam sheets to adjust the machine height to exactly where I needed it.  Table size is a perfect fit in a room set up with 2 other sewing machines (and cabinets), two sergers & a cover stitch machine!
