Falling out of bed is usually more embarrassing than LIFE-THREATENING. Assuming you're sleeping a couple feet off the floor and not on the EDGE OF A CLIFF.
A few weeks ago, someone set up a "cliff bed" in China, which allows thrill-seekers the chance to "sleep" on a bed that's perched 330 feet (or 100 meters) off the ground.
They're "only" charging $13.50 to do it, and you (probably) won't fall.
You have to wear a safety harness the whole time. And apparently it's even safe enough for kids. You can be as young as 14 to do it, though minors have to be accompanied by an adult.
You also don't stay in the bed overnight. There's a mattress and duvet . . . and you get a cup of morning "cliffside coffee" . . . but it's mostly just set up for a brief photo op.
