Death Bed: The Bed That Eats

"Who would have thought that a movie that admitedly is about a killer bed is actually some kind of exploitation art film?"

—The Cinema Snob reviewing the movie

In 1972, some guy named George Barry got a camera and some film.

What happened was Death Bed: The Bed That Eats.

An incredibly cheesy and bizarre mix of horror, sexploitation, and arthouse, Death Bed was shot in 1972 but a print wasn't struck until 1977. It then disappeared. before being rediscovered in 2003 and released on DVD, it gained a cult following when bootlegs made from a rare UK VHS/Betamax copy of the film began circulating. Director George Barry reportedly forgot about the film before he was reminded when a DVD release was in high demand.

Tropes used in Death Bed: The Bed That Eats include:

Attack of the Killer Whatever
B-Movie
Bizarre Alien Biology: There are plenty of scenes of the bed's digestive system, just for starters.
Colbert Bump: The movie would be even more obscure where it not for Patton Oswalt's routine on the film from Werewolves and Lollypops.
Dull Surprise: One of the guys loses the skin on his hands, and the remaining bones begin falling apart. He doesn't seem to mind though.
Everybody Has Lots of Sex: Well, it is about a bed... too bad most of them get eaten by the time they're done.
Major Injury Underreaction: Again, when the guy loses his hands.
Our Demons Are Different: They sleep only every ten years, their eyes are always full of blood and their tears can bestow sentience on inanimate objects.
Our Monsters Are Weird: Doesn't quite cover it...
Padding: There's a 5 minute scene of the black woman struggling to get up the stairs while the bed tries to drag her into its mouth. Her friend tries to save her, but fails.
Spiritual Sequel: Patton Oswalt's upcoming masterpiece Rape Stove.
Spooky Painting: Some guy is holed up behind a painting. We get to hear his discussions with the bed. The bed doesn't talk back.
Surreal Horror: Sort of. To be fair, it is about a demon-possessed bed eating people.
Stealth Parody: Some have suggested this, due to the absurd plot of the movie.
Tears of Blood: How baby Death Beds are born.
