Yes, it all depends on the type of targeted support you are looking for.
Combining different types of coils, like microcoils and pocket coils, in a mattress is a technique used by some mattress manufacturers to offer a blend of benefits. This approach can potentially provide a mattress with the advantages of both coil types. Here are some considerations if you’re thinking about using them together:
By combining microcoils and pocket coils, you may achieve a balance between targeted support and overall supportiveness. The microcoils can offer precise contouring and pressure relief, while the pocket coils provide deep support and stability.
Mixing coil types allows for customization of the mattress feel. You can adjust the ratio of microcoils to pocket coils to achieve the desired firmness level and support characteristics.
Microcoils can help reduce motion transfer, while pocket coils provide individualized support. Together, they may offer better motion isolation compared to using only one type of coil.
Using both microcoils and pocket coils may increase the manufacturing cost of the mattress, which could translate to a higher retail price. Consider whether the added benefits justify the extra expense for you.
It is important to ensure that the manufacturer has a good reputation for quality and craftsmanship of their coils. The effectiveness of combining different coil types depends on how well they are integrated into the mattress design and construction.
When it comes to the wool 3" topper, wool presents an intriguing quality (aside from its moisture wicking and heat neutrality)—it compresses to offer firmness yet retains a softness. In a recent conversation with Sawyer at Sonoma Wool Company about wool batting I purchased for a pillow project, we explored this duality. While he highlighted wool’s softness, I emphasized its role in providing firmness to complement a latex noodle core, essential for ensuring the pillow offers the head and neck support that I prefer rather than just the soft squishiness that the latex noodles offer alone. This is due in part because the wool will not allow the latex to expand quite as much as it does with no other material around it, or a stretchy material around it.
Just like the material used for mattress covers or sheets—whether stretchy or taut—affects the firmness and feel of a mattress, the materials, their combinations, and their arrangement play a pivotal role in determining the overall feel and comfort of a mattress and even a pillow.
For your wife, the combination of a wool topper with a latex core, while pricey, maybe the perfect combination for her overall comfort.
Maintenance!!!
I can not stress enough that maintenance plays a very important roll in overall comfort and longevity.
Rotate the mattress
Every 3 months. This is important when the mattress is new. The fibers and foams have not been “stressed”. When you sleep, body impressions are normal. One a king mattress in particular, you may develop that “ridge” between sleepers down the middle, head to foot. In a better quality mattress, this is due to each sleeper’s compressing their sides and the middle remains at expanded height, thus creating the ridge. Rotating the mattress, even at times, a 90 degree rotation will allow for even wear and be visually pleasing.
Topper Rotation and fluffing
I rotate and flip my 3" wool topper every time I change the sheets. The sheets are off anyway, so I rotate the topper, and fluff the mattress topper by shaking it multiple times, in a motion akin to the rope exercise, helping to redistribute the filling and restore its shape and loft. It does create a noticeable difference upon lying on the mattress after the linens are reapplied.
Long explanation for a simple question, but some things need to be viewed in a bit more depth.

yes if its a very high density foam it’ll work just fine.
