Pair of Victorian reproduction chairs (and a set of 6 drop-in dining room chair seats (same fabric): not shown).
In typical fashion, a previous upholsterer covered over the old cover rather than remove it (as we always do). You can also see that the seat is very bumpy/lumpy.
The reason that the seat was so lumpy was because the foam had torn through the springs. There is usually a burlap or other covering/barrier over the springs to prevent this from happening. The chairs were taken down to the bare frames, and new foam, cotton/padding was installed along with the new top fabric.
