Ah, the bed. A place of security, stability and relaxation where one can sleep your cares awa--

SNAP! The bed folds in half like a taco shell, trapping the occupant between the raised head and foot. If you're in a [[ComedyTropes comedy]], the only injury will be to your dignity, but if you're in a drama there are no guarantees...

A SubTrope of MurphysBed. See also BearTrap.

* Nordberg in ''Film/TheNakedGun'' movies, with his hospital bed.
** In another Leslie Nielsen movie, Dick Steele (Agent [=WD40=]) traps a would-be assassin in his fold-out bed. Then he goes to play some golf. Whether he did it deliberately is hard to tell, considering the character is either ObfuscatingStupidity, CrouchingMoronHiddenBadass, or a BunnyEarsLawyer.
* In JacquesTati's classic ''Film/MrHulotsHoliday'', this is done with a rowboat. Hulot's attempts to extricate himself lead to terrified beachgoers [[CoincidentalAccidentalDisguise mistaking said craft for a man-eating shark]].
* In the ''Film/JamesBond'' movies, Q occasionally tests one of these in his lab, often hurting some poor peon.
* In the film ''The Wrong Guys'', Richard Lewis attempts to set up a cot in a tent which keeps doing this to him. Eventually he ties this "cot from hell" in place, and is finally able to lie down on it. However, then another character actually causes the entire tent to collapse, and we can see the shape of the cot folding up again underneath it, while Richard screams in agony.
* In the Creator/StanleyKubrick adaptation of ''Literature/{{Lolita}}'', Humbert and Lolita arrive at a hotel and find ThereIsOnlyOneBed. This [[{{lolicon}} doesn't bother Humbert much]], but to keep up appearances he asks for a cot to be sent up. This leads to a short comic sequence where Humbert and a hotel porter have to unfold the cot without waking up Lolita. The cot does little to cooperate -- squeaking loudly, throwing Humbert onto the mattress and whacking the porter in the face. Finally they get it open without waking Lolita, only for her to wake up when Humbert tries to slip under the sheets with her. So Humbert has to use the cot, [[MurphysBed which promptly collapses on him]].

* One of [[Comicbook/GastonLagaffe Gaston]]'s invention is a switch-operated folding relaxing chair (conveniently next to many other switches that do something else). Before he tested it, he went home, but curiosity got the better of Fantasio and of course, he pressed the wrong switch...

[[folder: Live-Action TV ]]

* ''CrankYankers'' featured this in a segment.
* Granny from ''BeverlyHillBillies'' gets trapped in at least two beds in one episode.
* So did Marlo Thomas in ''ThatGirl''.
* In an episode of ''ILoveLucy'', Cousin Ernie is given a fold-up rollaway bed to sleep on and doesn't realize that he was supposed to un-fold it first. Lucy finds him sleeping ''through'' the bed, sideways.

[[folder: Western Animation ]]

* Often happens in cartoony hospitals, where someone in a full body cast will have the misfortune of having a bed that will painfully sandwich them. Showed up in ''WesternAnimation/TomAndJerry'', ''WesternAnimation/LooneyTunes'', ''{{Popeye}}'' and ''WesternAnimation/QuackPack'', among others.
* In one cartoon, DonaldDuck is eaten by a folding camp cot like this.
* In ''{{Rugrats}}'', ButtMonkey Chuckie gets trapped in one of these when he and Tommy descend into the Pickles' basement in search of a lost toy.
* In ''TheWuzzles'', Croc, seeking shelter from a tropical fruit storm (yes, as in a storm where it rains bizarre hybrids of tropical fruits, like coconut/bananas) by pretending to be injured on a "broken" step (which he himself broke) at Butterbear's, is tossed into bed by a Bumblelion who secretly witnessed his plan. The bed promptly folded up on him (Croc, not Bumblelion).
* Parodied in ''TheSimpsons'': Homer refuses to get out of bed, so Marge folds it up. We hear a crunch and see red fluid drip out. Terrified, Marge quickly unfolds it, and out tumbles Homer, perfectly fine, but crying over his crushed and dripping juicebox.
* ''PhineasAndFerb''. "Flop Starz" Doofenshmirtz falls from the top of a giant robot, only to land into the safety of a nearby bed, which then folds up on him. Talk about insult to injury.
* An early episode of ''TheJetsons'' showed George's bed folding up lengthwise to turn into a toaster, which then pops him out with all the vigor you expect of a six-foot-long toaster.
* In ''FairlyOddParents'', this is a feature of Mr. Sandman's magical Sleepmaster 9000 bed. This is only one of the bed's tricks, as it's designed to subdue people and fairies who are too cranky and violent to willingly accept sleep.

[[folder: Real Life ]]

* One spring-loaded canvas-on-a-metal-frame folding thing is generally used as a sun lounger. If you don't set it at the perfect angle, or if you sit down too hard or someone throws a well-aimed pebble, you are instantly trapped in a canvas sandwich that can't be opened from the inside. Thankfully, the frame only runs around the outside edge, leaving the victim only in danger of an uncomfortable squishing rather than a broken back.
* It's even worse when employed in combination with a hot water bottle.

[[folder: Film ]]

* In ''Film/FreddyVsJason'', [[Franchise/FridayThe13th Jason]] knifes up a kid in a rollaway bed, then folds it up -- with the kid inside being folded backward.
* Doesn't that giant plant that eats Poison Ivy in ''Film/BatmanAndRobin'' look like it might be her bed? That she's that overconfident of her plant-control powers and evil that she'd ''choose'' to sleep in a carnivorous plant?
** Except that at the end of the movie, she is shown alive in a cell in Arkham Asylum.

* On ''MyNameIsEarl'', one of the guys on Earl's list, Josh, dies via Bear Trap Bed.

* Not done with a bed but still an example. In ''VideoGame/BloodyGoodTime'', you can kill someone sleeping in a deck-chair by doing this to them.

* [[http://www.reuters.com/article/idUSL0919437820080709 A man in St. Petersburg]] was lounging on an unfolded sofabed after drinking. The next morning he and his wife got into an argument and she kicked the bed in a rage, then stormed out. Unbeknownst to her, the kick released its spring-loaded folding mechanism. It folded up with her husband in it and killed him instantly (strong springs + inertia + leverage + being extremely unlucky = broken spine). A few hours later she returned to continue and found him like this.
** Well, they say you shouldn't go to bed angry...
