Here's a product tester job you can literally sleep through. Some luxury bed companies conduct sleep surveys for feedback on how to get a good night's sleep. One company in England hired a cash-strapped student to sleep in its beds for a month and write about her experience [source: Telegraph].
She spent eight hours a day in bed under different conditions, experiencing variations in lighting and temperature. She also imbibed different amounts of alcohol or caffeine to experience other sleeping conditions. How do you get a job like this? In this particular instance, the student answered a call for applicants, and her writing skills gave her the edge over the hundreds of others who also wanted to sleep for cash.
