I'm trying to find a movie. I've only ever seen it as a kid, so it must've been from the 80s, or late 70s?

The scene I remember (bear with me here...), there are some teenagers or young 20s kids huddled in a room, dramatic lighting and music playing. In the middle of the room there's this couch. It's like a killer couch, where it has teeth, gnashing, etc. I believe I recall the kids are doing something that gets rid of the couch, like some incantation or something that sucks the couch back into some dimension, or the like. Or, perhaps the couch eats people by sucking them into a dimension. I can't recall.

I know this is vague, but this is all I can remember. Ring a bell, anyone?
