We're getting ready for season #2 on our '87 Oday 322, which we bought in very good condition, so the cushions have plenty of life left in them. But now we're making decisions about preferred sleeping berths and we'd like to make the salon area more comfortable (best view of the TV now custom mounted in the 'window' of the v-berth!) There is a center board insert that is used to make a full berth when the table is down, but the cushion that covers this is very thin and no one wants to roll over where it transitions (ouch). Our idea is to make a large cushion that covers the full area for our weekends on the bay. But I need to find a large piece of foam -- and have no idea where large foam is sold. We are DIY-er's and will cross the 'upholstery bridge' once we get to it. Thanks!
