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 due to the effects of a damp environment. You will find two suggestions below of our most popular grades however they are not waterproof so we recommend a waterproof or water resistant fabric if being used externally. Alternatively you may wish to use a specialist Reticulated foam for outside usage that will not retain moisture or liquid, However these will require vented covers to allow moisture and liquid to escape.

4" (7.6 cm) and below I would recommend the firm blue foam V 38 for firm seats and mattresses
4" (10 cm )and over I would recommend the Reflex 40 H Medium firm for seats and mattresses
Both these grade are highlighted in red once you have entered your sizes in the home page "Instant quote" calculator
