Front seat upgrade??

We recently bought a 99 CR-V for my wife and I think we are going to be very happy with it. But something I noticed right away that I don't like is the very uncomfortable front seats. I didn't notice it during the relatively short test drive. But the hour + drive home leaft me with a numb butt! I fiddled with the seat controls the whole way home trying to make myself more comfortable. I'm have a thin build and weigh about 170lbs. My wife, who let's say has a little more natural padding than I, doesn't seem to notice. I have since read many readers on edmunds.com with the same complaint. My questions is: Has anyone ever upgraded the front seats to something more comfortable? It may sound like a crazy idea, but I'm considering testing the front seats of our Sienna to see if they will fit. If so I can get a couple from a salvage yard. (The Sienna seats are very comfortable). Thanks for any help.
