Hi CKirk,
I’d never come across the Froli systems before and I don’t have any personal experience with them but they are certainly interesting. They are similar to some of the Axelbloom bases here but they are less costly.
With a thinner latex mattress they could certainly enhance the comfort of the mattress and they can also be customized to fine tune alignment as well. There is more about the pros and cons of tension adjustable flexible slat bases in post #2 here but with the ability to change the tension in any part of the base I would think that the odds are high that that it would work well if you would benefit from the extra flex and softness it provides…
I’ve also added them to the foundation reference post as well … and thanks for letting me know about them
