Which word do you use?
Growing up, we used to say settee, but at some point, we switched to sofa. I'm a Londoner, but my mum was from the Midlands, so I think that was a regional thing we got from her.
First I ever heard the term loveseat was in Sims 2 and I thought it was just an in-game thing.
Is that actually a word used in the UK? I'm assuming you're North American from the .ca tld?
