Wool Futon Pad
I have the eggcrate pad (and a Thermorest, too).My solution is a wool 3" futon pad (queen size)to be placed on top of the Hunter pad. I tried this out at Soaring Heart Futon Mattress shop (SoaringHeart.com)in Seattle a couple weeks ago.The wool stays cool and does not absorb moisture like a cotton pad would( major no-no). They laid one of these out on top of a 2 inch foam pad (to mimic my Hunter pad) and I tried it out. It will be my boat "improvement" somtime this winter. Now if I can figure out an easier way to hoist myself out of that under cockpit cabin first thing in the morning, I will have it made.
