Hi Jake,
I switched your post to a new topic of it’s own with a more descriptive title because your question was outside the scope of the topic you posted in.
An all latex mattress will generally do best with a firm, flat, and evenly supportive support surface underneath it that has minimal to no flex under the mattress and for larger sizes with at least one center support beam that has good support to the floor to prevent any sagging in the middle of the mattress. The components need to be strong and durable and stable enough to support the weight of the mattress and the people sleeping on it without some of the parts bending, sagging, or breaking over time. The support surface under the mattress should have enough surface area to prevent the mattress from sagging through any gaps or spaces in the support surface over time but still allow some airflow under the mattress. I would suggest that in a slatted support system (either a foundation on a steel or wooden bedframe or a platform bed with a slatted support surface) that any gaps between the slats are no more than 3" (with 1 x 3 slats) although less than that would be better yet.
There is also more information about the different support systems (bedframes and foundations or platform beds) that are generally suitable for different types of mattresses and some examples of each of them in post #1 here.
