Sitting by the fire

I have some firepits setup in key places, and my heartlings are using them just fine. However, they seem to insist on sitting on the ground instead of the benches that I set by the firepit. Is this by design (that they would sit on the ground, no matter what), or is there a way to make them sit on those benches that I am not aware of?

it’s “by design”, as hearthlings only sit on chairs/benches when eating…

but i definitely think it would be a nice/needed detail to have them sit on benches, something like “if placed within 3 blocks from the fire, sit in chairs when resting by the fire”
