Sorry not a helpful reply, but I'm curious what the new cushions end up costing?
We had the quarterberth cushions on our 303 recovered and just for a (nice quality, not outstanding) recovering was $321.... seemed on the high side to me, but was the same shop that had already done the settee and V berth cushions so at least they matched, and I didn't have to go out and find a shop that I trusted from scratch.
