Hi pigsmoker.
Welcome to our Mattress Forum. 
We’ve actually got a great forum topic on this already, which you might be interested in reading through.
Normally a slatted wood base with solid slats that are no more than 3" apart (or preferably less) is best for latex.
If you don’t find what you’re looking for in the link above, or have more questions, we’re always here to answer any additional questions that may pop up!
