The Best Foundations or Base for a Latex or All Foam Mattress

Hi CCoffey,

I’m not sure of the length of the span between the sides of your bed but if it’s not more than the width of a twin mattress (about 38") then you could use 5/8" good one side plywood (preferably low VOC … see here) on top of your bed to provide good support without needing center support. The down side to this would be a lack of airflow under the mattress which in combination with other risk factors could increase the risk of developing mold or mildew in your mattress (see post #10 here) although in most cases it would probably be OK if not ideal. You could also use a bunkie board to provide good support across the two sides your mattress which would be more breathable (see post #4 here and the post it links to) or you could add a bed rug on top of the platform to improve the ventilation under your mattress as well.
