Death Bed: The Bed That Eats (1977)

A man and woman kiss. He eventually removes her top, her breasts visible.

A woman undresses, her breasts visible.

A woman's dress is taken off of her, her breasts visible.

A woman is shown fully nude from behind, her butt visible. She kisses a man.

The film is about a bed that eats people. Some blood each time.

Damn.

Cigarette and cigar smoking.

Drinking.

The way the titular bed ate regular food prior to eating some victims in an early scene, while corny, highlights the way it kills people without actually showing it. Later on, the film drops all subtly and shows people getting eaten alive by the bed.
