If you get on the wrong side of a Cossack he will certainly split your difference!
Ottoman if I’m speaking English, “pouf” if I’m speaking French.
I like the way the Ant pronounces ‘ottoman’ in this Orkin commercial.
Southern Ontario here, of English descent.
I’d call it a footstool. I also call the wodden thing to stand on a footstool. I’ve heard the word ‘ottoman’ for them, but never used it. I was not familiar until this thread with ‘hassock’–I would have thought that was some kind of Catholic religious vestment.
And when I was a kid, we called the large multi-person seats ‘chesterfields’. This has slowly been replaced by ‘couch’ (not ‘sofa’), but there are still a number of furniture stores in the Toronto area with names like ‘The Chesterfield Shop’.
ETA: I just looked at Ikea’s Canadian pages. They call the thing in the OP a ‘footstool’ as well, but uses ‘sofa’ instead of ‘couch’. Interesting.
I call a giant beanbag a hassock.
I’m New York metro-area born and raised, and probably call it an ottoman or a footrest, with a 50/50 split for frequency.
