Seat frame dimensions?

[bugsoup]

Does anyone have quick access to a measuring tape? I need to know the dimensions of the frame of a type 1 seat. I have an opportunity to get a good deal on seats from an Audi A4 (leather, heat, power, etc) and want to know if they will fit in a Beetle. The frame of the Audi seats are 22 inches wide at the base and the side bolsters are about the same.

If someone gets a chance, could you measure this for me? I don't have my car out here at school, otherwise I would do it myself.
