More and more Koreans are opening their wallets, despite stagnant income growth and the tight job market, to purchase goods and services that help them get a good night’s sleep, reports The Korea Times.

“As consumers are more obsessed with wellness, they feel like they have to spend a lot of money in order to get a good night’s rest,” an official at Shinsegae Department Store said.

“The sleep industry has expanded to include products ranging from bed sheets and pillows to lighting equipment. Among them, bed sales have grown roughly five times compared to five years ago.”
