Sit toothy
I remember when I was little, I used to bite the arms of the sofa as they were made of wood. When we moved, my mom changed to the knobbly sort of design.
And I remember people did not throw out sofas in those days, but just changed the cushions. Virtually everyone had similar furniture in the house, just different color combos. Even the curtain clothes were 'standard'.
Those were the days :) People saved so much more then.
