Hi toddking2,
If your current foundation is a solid non flexing foundation then any non flexing foundation that has no “give” to it will be the same whether it is the floor, an adjustable bed, a platform bed, or a slatted foundation with gaps that are small enough to provide solid even support for the mattress and prevent the mattress from sinking into the gaps (for latex gaps of 3" or less is best).
As far as the benefits of a slatted foundation vs a solid surface … post #10 here has more about the pros and cons of each.
