The money mattress: A Spanish invention stores cash in beds

For Spanish businessman Paco Santos, the safest place to keep money is still under a mattress—or rather, inside it.

Santos, according to NPR, who was laid off from Spain’s largest mattress manufacturer three years ago, is the inventor of the Caja de ahorros Micolchon, or “My Mattress Safe." It's a plush, padded mattress with a keypad-equipped, armored safe built into the side.

After being contacted by NPR, Santos said the mattress was no joke. "We’re completely serious,” he said. “And we’ve sold many, many of these mattresses.”

According to NPR, My Mattress Safe sells for more than $1,100. Santos said the investment was worth it: “We’ve got big economic problems in Spain, and people have really lost their confidence in banks."

In a 59-second video that Santos made with the help of a son who works in PR, the inventor explains that his company wants to “reinvent the traditional method of saving money.”
