= Synagoge sigma129, Photius sigma356 Theodoridis; from commentary to Plato, Euthydemus 278B, where they are mentioned as pieces of furniture that jokesters would snatch away as people are trying to sit down, sending them tumbling onto their backs. The gloss 'foot-rests', i.e. stools, ought not to imply something that people actually (try to) sit on, however, and it may be misleading. An alternative and more convincing line of commentary calls them 'low seats': so e.g. Pausanias the Atticist, a scholion on the passage, and Timaeus' Platonic Lexicon (where they are identified as Thessalian).
