I think the correct name is antimacassar. You can still get at shops like Damart (who also do a catalogue) They are called chair backs and chair rests about �9.99 for a set.
for info anti-macassars were used in edwardian times to protect furniture from hair-oils, particularly maccasar oil. This comes from the macassar area of celebes and is a mix of oil from the ylang-ylang tree, coconut oil and other ingredients. And we all thought ylang-ylang was a new ingredient in hair care!!
