Discount Mattress Outlet outside of Columbia, Missouri, has something of a secret identity.

“It’s a mattress store by day, dance studio by night,” Linda Vorce told KBIA Mid-Missouri Public Radio. She co-owns the store with her husband Steve.

During the day, mattresses occupy the central floor space. But every Tuesday and Thursday, mattresses are moved to reveal a dance floor. Between 15 and 25 people come each week for Swing ’n’ Country Dance.

The Vorces originally started dancing in 2000 and loved it so much they became instructors, according to the KBIA story. They first started teaching in bars, but it wasn’t a good fit. It turns out the solution was under their feet the whole time.
