What We Like About This Futon Mattress A firm mattress is recommended for sleeping, and the Deluxe Firm Aerolife futon mattress in one of our better choices. At 6 inches thick, it is the recommended size for A frame and tri-fold futons. This mattress is constructed with three foam layers and a newly patented cotton blend fiber that will not clump over time. The new blend creates a thicker, softer product that is more lightweight, resilient, breathable, and durable. An excellent choice for a sleeping futon. Fits a full size futon frame.
