Hi AC,
Hybrid mattresses (such as an innerspring latex hybrid) have been on the market for many decades and they can be a great option. If it’s a good match for you in terms of PPP then a good innerspring with a suitable insulator (to even out the compression of the springs and prevent the foam from sinking into the coils) and a latex comfort layer can be a very durable option. If the coils are connected (such as the Bonnell that you are looking at) then I would make sure that you test the mattress for motion isolation as well if you are part of a couple. The “weak link” of a mattress in terms of it’s useful life is almost always in the comfort layers, not the support components, and latex is the most durable of all the foam materials that can be used on top of an innerspring.
You can read more about a foam or latex support core vs an innerspring in post #2 here.
As long as the support material or component is good quality, the choice between different types of support materials or components is really more of a preference and budget issue than a durability issue.
