Whilst it's good to see that more options are appearing on the market, going back to your specific application I would be very wary of most of them as they do little more than lull you into a false sense of security. They might be useful for a bit of added comfort, but I wouldn't want to rely on them in your situation.
Assuming your wife is generally fit, then the most practical answer would probably be to fit jockey seats and for your wife to stand up rather than sit at all. If that's not an acceptable option, then I'd suggest the Ullman seats (actually I'd probably suggest seriously considering whether a RIB was actually a good idea).
Bucket seats with suspension may seem to be a good idea, but if they work well then you will tend to use the boat harder, because it's fun. At the point where you come off a wave just that bit harder than the suspension can handle, a damaged back is going to become very vulnerable.
Not knowing the details of you wife's back condition, I would definitely suggest that you get medical advice on what the likely outcome of a harder than planned landing might be, and take that into account too.
