I am looking for the same thing. I am leaning towards one of those memory foam jobs that you can get at Sam's or Costco. the problem is storage vs. comfort. my V-berth on the P-27 is the table dropping down with a 4" pad on it and the settee. So i have to store it during the day. The Sam's has a 3" foam that is tough to roll up (i checked out the 24" x 24" sample they have laying out) Costco has a 2.5" faom + 1.5 in fiber pad for a total of 5" but it seams to roll better. When i make up my mind i will have it cut to fit.
