Got foam from Sailrite to make saloon cushions and cut it to size. Going with extra firm, 4in thick for seats and 3in thick for backs. No material (or time, really) to sew the covers yet. Used basic blankets to cover the foam and test it out. Sooooo much more comfy than sitting on bare fiberglass! I think the backs may be too high as I cut them initially. Will take them down by an inch or so when making the actual cushions.
Tested out both 4in and 3in thick pieces as mattress in the v-birth. Determined that 3 inches is totally enough for a comfortable rest so will order that thickness for all the sleeping cushions.
