We are often asked what is the best foam to use for boat mattresses. Foam used in a marine environment should be melamine free to prevent the foam foam disintegrating and turning to powder. You will find two suggestions below, however they are not waterproof so we recommend a waterproof fabric if being used externally.
3″ (7.6 cm) and below I would recommend the firm blue foam V 38
4″ (10 cm ) and over I would recommend the Reflex 40 H
