Sorry I didn't see this earlier. did not have to redo the dinette seat backs. Did have the dinette seat bottoms sent out, no new foam there just a recover. I bought new foam from a website: The Foam Factory or Foam by Mail, the same company, for the v-bunks and aft cabin. Also bought foam for the recovering of the V-bunk area as shown in the pics. Stapled it to the wood support structure. didn't want to use any adheisive as certain types can melt foam and besides the glue odor in the V-bunk area would be a problem I thought. I saved a ton buying foam from them over quotes I received in the Cleveland Ohio which were twice as much for the foam alone. I spent a total of about $1400 on foam, foam for the v-bunk & aft cabin matress's & the sunbrella heavy duty material & the local upholstery guy making the new matress covers & the dinette seats.
