'Grandma's Feather Bed' sparks memories

The other day I stumbled across a John Denver song on YouTube that I had never heard before, and then I started listening to other old favorites. Denver had a way of striking a chord on many different subjects. And ‘Grandma’s Feather Bed’ was one of them.
Part of it goes like this:
“But the best darn thing about grandma's house
Was the great big feather bed
It was nine feet high and six feet wide
And soft as a downy chick
It was made from the feathers of forty 'leven geese
Took a whole bolt of cloth for the tick
