We found our couch yesterday. I had done some research and found I should be looking for the coiled, 8-way hand tied (like they do mattresses) construction. Found a gorgeous set which had that in the frame AND in each individual cushion, plus a 'pillow top' attached to the top of each cushion. I was so impressed I wouldn't let mom or hubby get up off their seats. It's a store which buys discontinued or overstock, so it was the only set. Great deal! I can't wait, it will be delivered Monday.
Thanks ALL for the great input.
