Houston's Jim "Mattress Mack" McIngvale is out $10 million thanks to a bet he made with customers on the World Series.

McIngvale promised to refund customers of Gallery Furniture who spent $3,000 on mattresses if the Houston Astros won the World Series.

"It's the best thing we could ever possibly do. The Astros inspired the city. We're thrilled to give this money back to excited customers. We bleed orange out here," McIngvale told Chron.com Thursday morning.

BIG MONEY: Mattress Mack flies in 98 Astros fans for Game 6 of the World Series

McIngvale is no fool when it comes to making crazy bets. He reportedly took out an insurance premium between 10 and 20 percent of the total value of what he had to pay out to his customers and placed some bets on the Astros in Las Vegas that earned him at least $1 million, ESPN added.

"I had a pretty strong feeling that the Astros were going to win when we made the promotion in late June," McIngvale said in response to why he took out insurance.

On Tuesday, McIngvale flew 98 Astros fans to Los Angeles for Game 6 of the World Series. Of those people, 40 received free tickets to the game from McIngvale (the others already had their own tickets).
