Cool, it's not so much the sleeping space. More the space they take up in the room,
Yeah the space they take up in the room is quite small, just looking at mine I reckon the base would be similar to a bassinet or cradle (but then I've never had either of those so just a guess lol). I have mine in the lounge next to our couch because we only use it for day sleeps, and it fits perfectly right next to it.

The sleeping space is nice and long though, a toddler could easily fit in there.
