Casper, which launched eight years ago as a mattress company, is hiring people who want to sleep as much as possible.
Those selected will sleep in the company's stores serving as internal mannequins and influencers.
"This is not a dream and not a workout," a Casper spokeswoman said in a TikTok video.
For nearly a decade, the retailer has sold mattresses online with free returns after 100 nights.
But Casper's founders quickly realized they had underestimated how much people valued the physical experience of buying mattresses.
